            <p>Trees to 8 m tall, mostly epipetric. Older (woody) stems subquadrate to terete, irregularly fissured, sometimes ± scurfy, often lenticellate, lacking trichomes; younger (herbaceous) stems terete (when fresh), becoming flattened on drying, sparsely lenticellate, irregularly fissured, lacking trichomes. Leaves seasonally deciduous, clustered at shoot apex, petiolate, petioles to 90 mm long, sometimes tinged with pink or red, blades subsucculent, narrowly ovate to ovate to elliptic, 85–157 mm long, 31–76 mm wide, 1.8–2.7 × longer than wide, acute to acuminate at apex, acute to attenuate at base, surfaces glabrous (or rarely with very few scattered flexuose eglandular trichomes mostly on veins on abaxial surface, the trichomes especially evident on immature leaves), midvein sometimes pinkish to reddish purple (especially adaxially), margin entire. Inflorescence a terminal sessile or pedunculate thyrse to 38 cm long (including peduncle, if present, and excluding corollas), peduncle (if present) pubescent with erect to flexuose glandular trichomes 0.05– 0.7 mm long (glandular pubescent), rachis glandular pubescent and often with scattered erect to flexuose eglandular trichomes to 0.7 mm long as well; dichasia opposite or alternate, pedunculate, 1–many-flowered, to 120 mm long (excluding corollas), dichasial peduncles 15–60 mm long, pubescent like rachises. Bracts caducous (rarely present), lanceolate to lance-ovate, 6.5–7. 5 mm long, 2.5– 2.8 mm wide, abaxially pubescent like rachis (except sometimes with more eglandular trichomes). Bracteoles and secondary bracteoles caducous, lance-subulate to linear to ovate-elliptic, 2–7 mm long, 0.9– 2 mm wide, abaxially pubescent like rachis or with more eglandular trichomes. Flowers pedicellate, pedicels 25–50 mm long, glandular pubescent. Calyx 10–16 mm long, lobes fused at base for 1.5– 3 mm, subhomomorphic to subheteromorphic, membranaceous, lanceolate to ovate, 7. 5–12 mm long, 3–7 mm wide, subequal or with posterior lobe either slightly larger or smaller than lateral lobes, acute at apex, abaxially pubescent with erect to flexuose glandular and eglandular trichomes 0.05– 0.3 mm long, posterior lobe subplanar to subconduplicate. Corollas greenish, 35–65 mm long, externally pubescent with erect to flexuose glandular and eglandular trichomes 0.05– 0.3 mm long, tube 25–30 mm long, narrow proximal portion 7–12 mm long, 7–11 mm in diameter near midpoint, throat 15–25 mm long, 26–30 mm in diameter at mouth, lobes spreading to recoiled, ovate to subcircular, 15–24 mm long, 16–24 mm wide, rounded and emarginate at apex. Stamens 4, 65–80 mm long, filaments distally glabrous, pubescent with eglandular trichomes near base, thecae 8–11 mm long; staminode 0. Style 75–77 mm long, glabrous distally, pubescent near base with eglandular trichomes, stigma subequally 2-lobed and ± funnelform, lobes elliptic to subspheric, 2–3 mm long, 1.5– 3 mm wide. Capsules 32–42 mm long, 6–9. 5 mm in diameter, pubescent with erect to flexuose eglandular and subsessile to stipitate glandular trichomes less than 0.05– 0.4 mm long, stipe 2–5. 2 mm long. Seeds 16–24 per capsule, 5. 5–7 mm long, 4. 5–6 mm wide, surfaces smooth.</p>
            <p>PHENOLOGY.— Flowering: March; fruiting: March. Field observations on Daniel &amp; Steinmann 11913 reveal that no flowers were open between 16:00–17:30 on the first day of observations, but several very large floral buds were present. On the following day, all of the large buds were found to be fully open at 08:30, and no visitors were noted over the course of an hour.</p>
            <p>DISTRIBUTION AND HABITAT.— West-central Mexico (Michoacán; Fig. 8); plants occur on exposed limestone, often on steep slopes of arroyos, in tropical subdeciduous forests at elevations from 200 to 590 meters.</p>
            <p>ILLUSTRATIONS.— Figure 2A–E; Richardson (1972:66, fig. 2).</p>
            <p> CONSERVATION.— Except for  L. rzedowskianum , which is known from a single site,  L. brevicalyx has the smallest known EOO (0.27 km 2) among its congeners. At the site of Daniel &amp; Steinmann 11913, about 100 plants were seen growing, mostly epipetrically, in an area of ca. 5000 m 2 on exposed limestone slopes in forest. No protected land appears to be within the species EOO. Evident threats to this species appear to be large-scale mining in the vicinity of Daniel &amp; Steinmann 11913 (ca. 1.5 km distant) and deforestation for agriculture (including cattle) that is evident within the small EOO and in adjacent regions. Given the size of the EOO and apparent major threat (i.e., deforestation for agriculture), a single location is evident. A preliminary conservation assessment of Critically Endangered (CR; B1, a, b; IUCN 2017) is proposed for  L. brevicalyx . </p>
            <p>DISCUSSION.— Leaves are absent on the field specimens examined. Information on young stems and leaves provided above is from cultivated plants (Daniel &amp; Steinmann 11913cv). Leaves of these plants may not have attained the maximum size encountered in natural settings. The inflorescence, which appears before the leaves, arises from the apex of the previous season’s woody growth and bears a stalked (pedunculate) thyrse or a sessile rachis subtended by axillary dichasia (sessile thyrse). A stem forms with the flush of new clustered leaves later in the season.</p>
            <p>Most calyces have the three lobes that are characteristic of the genus. Five lobes with three prominent lobes and two reduced lobes are evident on Hinton et al. 15843; the reduced lobes are 3 to 6 mm long and 0.8 to 2 mm wide. Five-lobed calyces in inflorescences are likely teratological and suggest suppression rather than fusion of lobes for typical plants with three-lobed calyces.</p>

Stamens 4, 55–77 mm long, distally glabrous, pubescent near base with eglandular trichomes, thecae yellowish green, 6.5–9. 5 mm long; staminode 1, ± triangular, 0.1– 1.5 mm long. Style 60–67 mm long, glabrous, stigma unequally 2-lobed and ± obliquely funnelform, 1.5– 2 mm long, lobes ± elliptic, 1– 1.5 mm long, 0.6– 1 mm wide. Capsule (20–) 23–26 mm long, 4–6 mm in diameter, glabrous, stipe 1.5– 2 mm long. Seeds up to 16 per capsule, 4– 4.5 mm long, 3–4 mm wide, surfaces with subconic to low rounded protrusions or becoming smooth.</p>
            <p>PHENOLOGY.— Flowering: January–March; fruiting: February–March, June. In the two populations of this species observed for ca. one hour each, floral buds were present on the plants at both sites during daylight hours (morning for Daniel 8294 and afternoon for Daniel &amp; Butterwick 5905), and mature fallen flowers were present on the ground at one site (Daniel 8294). Likewise, Brewer et al. 7176 notes that the corollas fall in the morning.</p>
            <p> DISTRIBUTION AND HABITAT.—   East-central Belize (Belize, Cayo; Fig. 10); plants occur on steep limestone slopes in evergreen seasonal forests (tropical evergreen seasonal broadleaf lowland forest fide Meerman and  Sabido 2001) at elevations from 10 to 120 m. </p>
            <p>ILLUSTRATIONS.— Figure 12; Leonard (1936:197, fig. 1).</p>
            <p> CONSERVATION.— Daniel (1997) noted that the population at the type locality had been destroyed by quarrying activities, but that other populations had been located on several of the small, isolated, and steep limestone hills in the southern portion of the coastal plain in Belize District.  Louteridium chartaceum has since (i.e., in 2005) been located in Cayo District, as well. Plants occur in at least three protected areas, and the species’ EOO (189 km 2) includes a portion of another one. Ecologist and botanist Steven Brewer (in litt., 14 May 2018) indicates that the species “is common though not abundant on ridge-tops and exposed limestone along the north side of the Maya Mountains in Cayo and Belize districts.” Brewer (in litt., 22 May 2018) also notes that in this region, potential threats to all of the limestone forests include land conversion via agriculture (both in and around protected areas), encroachment or settlement in protected areas, and fire (either natural or “escaping” flames from regular burning used to clear nearby agricultural fields or bush). In the same communication, Brewer also observed that, “  L. chartaceum (though I doubt the same is true for  L. donnell-smithii ) is surprisingly resilient from the effects of even very hot fires. Natural light fires are occasional on those limestone hills and so it seems that most species there are tolerant or resilient in the face of light fires.” Scant change in vegetation cover within the EOO is evident from the historical imagery (1969 to 2016) seen via Google Earth Pro (2018). If the three protected areas in which the species occurs are treated either as a single or multiple locations, and the unprotected areas are treated as another location under threat (i.e., conversion of nearby, and partly within the EOO, land to agriculture as an inferred or projected threat), a preliminary conservation assessment of Endangered (EN; B1, a, b) can be proposed for  L. chartaceum . </p>
            <p> DISCUSSION.— Plants grown in San Francisco from cuttings of  Louteridium chartaceum from the type locality (Daniel &amp; Butterwick 5905cv) produced floral buds that attained 35 mm in length but abscised prior to opening. Both thyrses and racemose thyrses are present on Brewer et al. 7176. Bracteoles of a pair are sometimes fused basally for about 1 mm, at least along one side. </p>

            <p> DISTRIBUTION AND HABITAT.—  Costa Rica (Cartago, Guanacaste, Heredia, Limón, Puntarenas, and San José) and  Panama (Bocas del Torro, Chiriquí, Colón, and Guna Yala), primarily (or exclusively?) on the  Caribbean versant (Fig. 9); plants occur in and along streams in lowland to montane wet forests and cloud forests at elevations from 15 to 1700 m  . </p>
            <p>ILLUSTRATIONS.— Figure 4A, B; Durkee (1978:232, fig. 20); Durkee (1985:14, fig. 12).</p>
            <p> CONSERVATION.—  Louteridium costaricense has the largest EOO (61,058 km 2) among congeners. Its EOO includes at least 23 protected areas (16 in Costa Rica and seven in Panama), and the species has been collected in five of them. Although there are undoubtedly threats to the species in various portions of its extensive geographic range, considering its overall distribution and relative abundance, the species is here assessed as Least Concern (LC; IUCN 2017). </p>
            <p> DISCUSSION.— Corollas of  Louteridium costaricense are more tubular and generally less open than in congeners. No significant differences were encountered between plants from Costa Rica and those from Panama. Considerable variation is evident in the shape and width of corolla lobes from oblong-lanceolate to lance-ovate and 7 to 12 mm wide (e.g., Tonduz 8123) to ovate-cordate and 21 to 32 mm wide (e.g., Herrera &amp; Gamboa 8581). </p>
            <p>

Seeds up to 16 per capsule, 5. 2–7 mm long, 5–6. 4 mm wide, surfaces smooth.</p>
            <p>PHENOLOGY.— Flowering: February–March; fruiting: March–April. Based on field observations and cultivated plants (Daniel et al. 11894cv), flowering occurs on leafless (or nearly leafless) plants during the dry season. Near the end of the dry season (e.g., late March–April) when flowering is waning and fruits are mature, a new flush of vegetative growth appears from axils of clustered leaf scars at the base of the inflorescence, which eventually falls away. New internodal stem elongation (e.g., the young stems of the description above) takes place from the axil of a leaf scar on the old growth and terminates in a cluster of new leaves and/or between at least one of the pairs of leaves in the cluster and the remaining cluster.</p>
            <p> Field observations of Daniel et al. 11894 over three days (24–26 February 2012) revealed: day 1 between 08:00–09:00 (light) — corollas mostly fallen, only a few from previous night still attached to tree; day 2 between 19:00–20:00 (dark) — all corollas open, ca. 100 seen, bats active around plants but none seen visiting flowers, no floral odor detected and no nectar visible in saccate tube of undissected corollas, stigma extended ca. 1 cm beyond anthers on fresh flowers, stigma of 7 flowers examined for pollen (all pollinated); day 3 between 17:30–18:30 (light) — many corollas open and many others still in bud, corollas open fully (including recurving of corolla lobes) in 15 to 20 seconds, open flowers actively visited by Cinnamon Hummingbird (  Amazilia rutila , species det. by Jeff Chemnick), birds probe for nectar once or twice at same flower before moving on, nectar is located behind a barrier (seen in dissected flowers) at the base of the tube, nectar not visible in the saccate throat, birds appear to contact anthers with head or back and presumably contact the stigma on some visits as well, birds visit between 5–10 flowers on a single plant or on multiple plants before moving away from an area or resting on a branch, 2 flowers were observed to open and when subsequently visited by a hummingbird (one flower visited once, other flower visited twice) they were checked for pollination (no pollen observed on stigma of either), small bees or flies also observed visiting flowers but they only contact anthers, buds continue opening until full darkness (at 18:30); day 3 between 18:30–20:30 (dark) — hummingbirds no longer active, bats very active around plants but none observed visiting flowers. </p>
            <p>On a single flower of Daniel et al. 11894cv grown in San Francisco, corolla lobes began to separate at 15:50 and the corolla was fully open (lobes spreading 90° with respect to the throat or reflexed) with the stamens and style fully exserted by 16:15. By 18:00, all corolla lobes were at least partially recoiled. At 23:00, 6.5 μl of nectar was encountered in the nectar chamber, and the stigma was dusted with pollen from the anthers. At 07:15 the next day, 72.1 μl of nectar was recovered from the nectar chamber. The corolla abscised and fell from the persisting flower at 07:45. Thus, the corolla of the pollinated flower persisted for ca. 16 hours.</p>
            <p> DISTRIBUTION AND HABITAT.—   Southern Mexico (Oaxaca; Fig. 8) in the Sierra Madre del Sur and the  Isthmus of Tehuantepec ; plants occur on limestone (often karstic) slopes of streams in tropical deciduous forests and tropical subdeciduous forests at elevations from 600 to 750 m. </p>
            <p>ILLUSTRATIONS.— Figure 2F–L; Daniel (2017:143, fig. 8).</p>
            <p>CONSERVATION.— A discussion and preliminary conservation assessment of Endangered (En) was proposed for this species (B1, a, b; IUCN 2017) by Daniel (2017).</p>
            <p> DISCUSSION.—  Louteridium dendropilosum is unique among congeners by its dendritic trichomes, which are present on both vegetative and reproductive organs. Trichomes of other species may consist of one or more cells and be either glandular or eglandular, but they are not branched. Bracts and bracteoles are caducous prior to maturation of the flowers associated with them; thus, they are rarely encountered and are not present on any of the wild-collected specimens. The data on their shape, size, and pubescence noted above were taken just prior to their dehiscence from the young inflorescence of a cultivated plant (Daniel et al. 11894cv). </p>

Seeds 12–16 per capsule, 4.5– 5.5 mm long, 4–5 mm wide, surfaces minutely papillose in longitudinal rows.</p>
            <p> PHENOLOGY.— Flowering: November–June; fruiting: December–June. Brewer et al. 5748 notes corollas opening at night, just after dark. Davidse &amp; Brant 32089 and Gregory 612 note corollas opening at dusk or in the evening and withering by sunrise. Daniel (2010) noted floral color forms with different flowering times (see below). Fredy Archila (in litt. January 2012) observed both bats and moths visiting flowers of  L. donnell-smithii in and around Cobán, Guatemala over a period of years. </p>
            <p>DISTRIBUTION AND HABITAT.— Southern Mexico (Chiapas), Belize, Guatemala, Honduras (Fig. 10); plants occur, usually on limestone (often karstic), on slopes and along streams in lowland moist to wet forests, mesophytic montane forests, montane rain forests, and cloud forests at elevations from 1 to 1600 (to 2100) meters.</p>
            <p>ILLUSTRATIONS.— Figures 13, 4C, D; Lindau (1895:294, fig. 118); Gibson (1974:407, fig. 90).</p>
            <p>LOCAL NAMES.— “Carreton” (Lentz et al. 2428), “matacucuyuchi” (Miranda 7163); “oxox če” (Williams &amp; Wilson 40437 and Wilson 40943, Quecchí name); “palpalte” (Ochoa 80); “tabaco silvestre” (Contreras 5510); “vejiga” (Standley 91236); “ulul k’uum” (Ventur 177).</p>
            <p>USES.— Williams &amp; Wilson 40437 notes that the young growth is eaten; Ochoa 80 indicates that “esta planta es comida por el jabali.”</p>
            <p> CONSERVATION.—  Louteridium donnell-smithii  is the most commonly collected species of the genus, and it is also infrequently cultivated in botanical gardens.  Its EOO (32,499 km 2)   encompasses all or parts of at least 40 protected areas (10 in Belize, 19 in Guatemala, 9 in Honduras, two in Mexico).  Collections of the species have been made in 13 of these areas. The species has been abundantly collected in most portions of its EOO  ,   and in some regions it was sometimes noted on collection labels or observed (TFD) to be common.  Fredy Archila of Cobán , Guatemala indicates (in litt. Jan 2012) that in the vicinity of Cobán there were hundreds of trees of  L. donnell-smithii in the 1980s. Although most of these are no longer extant, some still remain as street trees in that city. Based on these data, this species is accorded a preliminary conservation assessment of Least Concern (LC)  . </p>
            <p> DISCUSSION.— In the protologue, Watson (1888) provided the collection information cited above. The holotype has been cited by various authors (e.g., Richardson 1972; Daniel 1995) as being at US. Indeed, a specimen there (accession: 1320518 with image number: 00136468) was annotated by D. Gibson and T. Daniel as the holotype. This somewhat fragmentary specimen, originally in H. Rusby’s herbarium, bears von Türckheim’s number 856 (as indicated in the protologue), but notes a collection date of February 1886. The date of collection of the specimen from Pansamalá indicated in the protologue is May 1887. The specimen at GH, where Watson conduct- ed his studies, bears the date noted in the protologue and an annotation written by Watson stating, “  Louteridium Donnell-Smithii , Watson-n. gen.” Therefore the specimen at GH indicated above conforms to the information in the protologue. The earlier annotations by Gibson and Daniel of the specimen at US are considered to be erroneous, and the specimen at GH noted above is treated as the holotype. This flowering and fruiting specimen lacks leaves, which are described in the protologue. However, drawings of the leaves are on another sheet at GH bearing the same barcode number. If the drawings are original material, the holotype would be considered as mounted on two sheets, and if they were made subsequently, the sheet with an inflorescence, flowers, and fruits would be considered as the holotype. Other collections that bear von Türckheim’s number 856, but with a date of February 1886, are located at the following herbaria: K, NY, P, PH, US (although one of three specimens at US has both “1887” and February 1886 on it). Whether these represent isotypes with an incorrect date (i.e., actually collected in May 1887) or the same collection number was used for gatherings of this species during different visits to Pansamalá on various dates remains unknown. </p>
            <p> Daniel (2010) noted variation in the timing of anthesis, color of corollas, and diurnal visitation to dark-colored flowers by hummingbirds in this species. There is a possible correlation with cream to green-yellow corollas at lower elevations and chestnut to maroon corollas at higher elevations. Based on specimens of  L. donnell-smithii at F, which are mostly from Guatemala, plants with cream to green-yellow corollas occur from 75 to 630 m, whereas those with chestnut to maroon corollas occur at 1000 to 2100 m. Figures 4C and D show these extremes of corolla coloration in Guatemala. Other flowers show various degrees of maroon coloration on cream-yellowish corollas. Based on a larger sample of herbarium specimens that include data on corolla color and elevation, it would appear that both the cream to green-yellow and chestnut to maroon color forms occur in Chiapas, Belize, and Guatemala, but that there is no clear difference in elevational ranges of these forms in Chiapas and Belize. However, it is somewhat difficult to correlate corolla color and elevation from herbarium specimens because of variation in the terminology of colors used by collectors. Additional studies that address the different (or at least partially so) flowering times of the different color forms and their primary pollinators, as well as any correlation of floral color with elevation, are desirable. </p>
            <p> The inflorescence of  L. donnell-smithii is commonly a somewhat contracted thyrse at the proximal nodes (with dichasial peduncles usually to 5 mm long) and a raceme (with sessile dichasia) distally. Several collections (e.g., Armour &amp; Chable 6047, Hawkins 981, Vargas et al. 1183) have exceptionally elongate peduncles (to 90 mm long) with expanded dichasia (e.g., secondary peduncles to 55 mm long). These latter dichasia are usually only at the proximal 1 to 3 nodes. </p>

Inflorescence of axillary and/or terminal subsessile to pedunculate thyrses (main axis with lateral pedunculate dichasia appearing as branches) to 250 mm long, peduncle to 50 mm long, pubescent with erect to flexuose eglandular trichomes 0.05–0.2 (–1) mm long, rachis pubescent with erect to flexuose eglandular trichomes 0.1–0.4 (–1) mm long; dichasia opposite, pedunculate, 1–3 (or more)-flowered, to 63 mm long (excluding corollas), dichasial peduncles 3–20 mm long, pubescent like rachis. Bracts caducous, lance-elliptic to elliptic, 12–17 mm long, 3.5– 5 mm wide, abaxially pubescent with erect to flexuose eglandular trichomes 0.05– 0.2 mm long. Bracteoles and secondary bracteoles usually present on young inflorescences but becoming deciduous as inflorescence matures, lance-elliptic to elliptic, 7–14 mm long, 2–3. 5 mm wide, abaxially pubescent like bracts. Flowers pedicellate, pedicels 10–50 mm long, pubescent like rachis. Calyx 17–28 mm long, lobes subheteromorphic, membranaceous, abaxially pubescent with erect (to ± antrorse) eglandular trichomes 1–2 (–2.3) mm long, posterior lobe planar to ± conduplicate, ovate-elliptic, 17–25 mm long, 11–15 mm wide, usually slightly larger than lateral lobes, acuminate at apex, lateral lobes ovate-elliptic to elliptic to obovate, 15. 5–22 mm long, 9–15 mm wide, rounded to acute at apex, veins of lobes prominent (ca. 9 major veins). Corolla “pale green” to greenish yellow, 50–55 mm long, externally glabrous, tube 29–33 mm long, narrow proximal portion 9–13 mm long, 9–16 mm in diameter near midpoint, throat 15–20 mm long, 30–35 mm in diameter at mouth, lobes spreading to recurved, “narrowly ovate to subcircular” (fide Miranda and McVaugh 1962), 18–24 mm long, 17–27 mm wide, round- ed to acute at apex. Stamens 4, 72–90 mm long, filaments glabrous distally, pubescent proximally with eglandular trichomes, thecae 10–12 mm long; staminode (if present) not seen. Style 50–55 mm long, glabrous, stigma lobes 1.5 mm long, shape and width not determined. Capsule 25–30 mm long, 7–10 mm in diameter, pubescent throughout with erect to flexuose to antrorse eglandular trichomes 0.05– 0.2 mm long, stipe 1.5– 2 mm long. Seeds up to 16 per capsule, 7–8 mm long, 5–6 mm wide, surfaces minutely papillose.</p>
            <p>PHENOLOGY.— Flowering: December–February; fruiting: February.</p>
            <p> DISTRIBUTION AND HABITAT.— West-central Mexico (Jalisco, Michoacán; Fig. 8); plants occur on limestone slopes in “high forest dominated by  Brosimum ” in regions of tropical subdeciduous and deciduous forests at elevations from 500 to 1400 meters. </p>
            <p>ILLUSTRATIONS.— Figure 14; Miranda and McVaugh (1962:183, fig. 2).</p>
            <p> CONSERVATION.—  Louteridium koelzii  is currently known from a very limited region of western Mexico (EOO = 5.3 km 2; AOO = 12 km 2). The species is not known to occur in a protected area, and it has not been recollected since 1975 (i.e., McVaugh 26180; although see discussion below about an undetermined plant from a nearby region of Jalisco).  Based on current knowledge, there appear to be two subpopulations about 80 km apart, one in Jalisco and one in Michoacán.  Comparing historic landsat images (2006 to 2017) via Google Earth Pro (2018) in the region of the known collections from Jalisco, it is evident that deforestation for agriculture has reduced the natural vegetation there substantially (ca. ≥ 30%), thus creating a threat to this species, at least in that region.  No specific threat has been identified for the subpopulation in Michoacán.  Thus , there are two locations for the species, and a threat is evident for one of them.  Based on these observations, a preliminary conservation assessment of  Endangered (EN; B1, a, b) is proposed for  L. koelzii . </p>
            <p> DISCUSSION.— An undetermined specimen of  Louteridium from western Mexico (Jalisco: Mpio. Jilotlán de los Dolores, Cerro de San Antonio, 15 km N de Tazumbos, matorral subtropical en suelos con pedregocidad de toba volcánica, 900 m, 6 Feb 1982, F. Santana Michel 1081, IBUG) does not seem to pertain to either species known from nearby regions (i.e.,  L. brevicalyx or  L. koelzii ) or other species of the genus. The plant, which lacks mature flowers, is geographically closest and morphologically most similar to  L. koelzii . Like that species, it occurs in an apparently dry habitat and has seasonally deciduous foliage. Both of these characteristics suggest that the undetermined plant has four stamens. Other characteristics in common with  L. koelzii include erect to flexuose eglandular trichomes on the rachis, peduncles, and pedicels; ovate-elliptic calyx lobes, and externally glabrous corollas. It differs from specimens of  L. koelzii studied herein by having pubescent young stems, shorter calyces (14–15 mm long, although the flowers are not fully mature), and longer (35–40 mm) capsules that are pubescent only at the apex. Disposition of this plant awaits further studies and/or collections. </p>

            <p>PHENOLOGY.— Flowering: September–May; fruiting January–May. Based on greenhouse observations of Breedlove &amp; Daniel 70879gh, corollas open after 17:00 and all fall by 11:00 the next morning.</p>
            <p> DISTRIBUTION AND HABITAT.— Southern Mexico (Chiapas, Oaxaca, Puebla, Tabasco, Veracruz) and Guatemala (Alta Verapaz, Petén) (Fig. 11); plants occur on slopes and along watercourses on limestone (often karstic) in primary or secondary lowland rain forests (selva alta perennifolia), montane rain forests, cloud forests, and evergreen seasonal forests (including selva mediana subperennifolia) at elevations from 50 to 1200 m. The distribution of this species appears to be entirely on the versants of the Gulf of Mexico and the Caribbean Sea. Daniel et al. (2012) report- ed this species from Guatemala. Plants from Guatemala previously attributed to  L. mexicanum pertain to  L. purpusii (see discussion in Daniel 1995). </p>
            <p>LOCAL NAMES.— “K’o’och batz’” (Paniagua 539); “oj-oj” (Kunkel 161); “palo aguañoso” (Ramos &amp; Martínez S. 620); “sabal tzununte” (Palacios E. 9631); “Uc’o’och chuba’atsir wis” (Levy T. &amp; Durán F. 398).</p>
            <p>USES.— Leaves applied against the body for fever (Wendt et al. 3614); a drink made from the boiled leaves is used for “dolor orinar” (Paniagua 539).</p>
            <p>ILLUSTRATIONS.— Figures 4E, 15.</p>
            <p> CONSERVATION.—  Louteridium mexicanum is the most commonly collected species in Mexico, and has an EOO of 35,531 km 2. At least nine protected areas are located entirely or partially within its EOO, and the species has been collected in two of them. Frequency data from herbarium collection labels varies from scarce to infrequent to common to abundant. Although unidentified threats are undoubtedly present in portions of its geographic distribution, a preliminary conservation assessment of Least Concern (LC) is proposed for this species. </p>
            <p> DISCUSSION.— Daniel (1995) discussed the probable state from which the type was collected; this would appear to be Veracruz rather than Chiapas. Linden collected in both states (Ossenbach 2009), but no “Zacualpan” has been located in Chiapas (D. Breedlove, personal communication in 1994). Zacualpan (or Zacuapan or Zacuapam [ca. 19°12’46.44”N, 096°51’8.73”W], see Sousa S. 1969; not the town of Zacualpan at 20°26’1.71”N, 098°20’57.69”W in northwestern Veracruz), Carl Sartorius’ large hacienda located between Jalapa and Córdoba in west-central Veracruz, with its headquarters at El Mirador, is known to have been visited by several early Mexican collectors, including Linden (Ossenbach 2009). Because it is ca. 42 km north of the currently known distributional range of  L. mexicanum (Fig. 11), and because of the ambiguity of the locality based on Linden’s indication of Chiapas on the collection labels, Zacuapam (shown in Fig. 11 with a question mark) is not included in the calculation of the EOO for the species. </p>
            <p>Based on living flowers of Breedlove &amp; Daniel 70879cv, the coloration of corollas of this species can be more fully described as follows: the narrow proximal portion of the tube (covered by the calyx) is green; the throat is green with maroon veins and tinged with maroon between the major veins; the lips (with recoiled lobes) are mostly maroon.</p>
            <p> Daniel (1995) noted considerable variation in pubescence, leaf shape, bract persistence, and bract shape among specimens from Chiapas, Mexico. One of the two collections (Breedlove 24803, Palacios E. 385) that he indicated showed some intermediacy with  L. donnell-smithii in pubescence was sampled in the phylogenetic analysis. Palacios E. 385 was strongly supported as nested within the clade of other sampled plants of  L. mexicanum (Fig. 1). Thus, both plants are here included within  L. mexicanum . </p>
            <p> Somewhat atypical plants from the vicinity of San Felipe Usila, Oaxaca (e.g.,  Ibarra M. et al. 3758, 3765; Calzada et al. 16579) are distinctive by their long calyces (30–39 mm) with the posterior lobe conspicuously attenuate-falcate apically, corollas pale rose to white with purplish lobes and pubescent with glandular and eglandular trichomes to 0.2 mm long, and rachis (i.e., Calzada et al. 16579) often somewhat scurfy to minutely puberulent with sessile to subsessile glandular trichomes less than 0.05 mm long. In Calzada et al. 16579, the calyx and pedicels are like more typical specimens of  L. mexicanum , and the rachis often has longer eglandular trichomes to 0.1 mm as well. Although similar calyces and trichomes on corollas are sometimes seen elsewhere among specimens of  L. mexicanum , the corolla color of these collections appears to be unusual compared to other Mexican representatives of the species. However, corollas of Foerther et al. 10940 from Guatemala are described as brownish violet. In pubescence of the rachis, these plants somewhat resemble  L. purpusii . On the whole, they appear more like  L. mexicanum , in which species they are treated here. </p>

            </p>
            <p>Shrubs or trees to 3 m tall, epiphytic or epipetric. Older (woody) stems subquadrate to subterete, lenticellate, lacking trichomes; younger (herbaceous) stems quadrate-sulcate, glabrous. Leaves not all seasonally deciduous, evenly distributed along stems, petiolate, petioles to 20 mm long, blades coriaceous-subsucculent, oblanceolate to obovate, 50–200 mm long, 15–63 mm wide, 3.3–5 × longer than wide, acute-apiculate (to caudate) at apex, attenuate to long-attenuate at base, adaxial surface glabrous, abaxial surface with scattered flexuose to antrorse eglandular trichomes to 1 mm long (or sometimes nearly glabrous), margin entire. Inflorescence a terminal pedunculate thyrse to 27 cm long (including peduncle and excluding corollas), peduncle 3. 5–15 cm long, glabrous, rachis glabrous; dichasia modified by sympodial expansion and appearing like dichotomous branches with zig-zag nodes, alternate, pedunculate, 1–many-flowered, to 100 mm long (excluding corollas), dichasial peduncles to 55 mm long, glabrous. Bracts caducous, lance-ovate to elliptic, 7–15 mm long, 4–8 mm wide, abaxially glabrous. Bracteoles and secondary bracteoles persistent, ovate to ovate-elliptic to broadly elliptic, 6–11 mm long, 5–7. 5 mm wide, abaxially glabrous (or inconspicuously glandular-punctate), those of a pair connate along one side for up to 1/2 their length and proximally subsaccate, sometimes conspicuously imbricate. Flowers pedicellate, pedicels to 30 mm long, glabrous. Calyx 24–39 (– 48 in fruit) mm long, lobes heteromorphic, apparently subsucculent, abaxially glabrous, posterior lobe conduplicate, oblong to subelliptic to oblanceolate, 22–45 mm long, longer than lateral lobes, 7. 5–14 mm wide, saccate or with a flap-like appendage to 2.5 mm long at base, rounded to acute at apex, lateral lobes lance-ovate to lance-linear to linear-oblong, 19–44 mm long, 5–8. 8 mm wide, acute at apex. Corolla pale greenish, 45– 72 mm long, externally glabrous, tube 25–35 mm long, narrow proximal portion of tube 0.5– 3 mm long, 6–8. 5 mm in diameter near midpoint, throat 24–33 mm long, 28–40 mm in diameter at mouth, lobes spreading to recurved, subtriangular to broadly ovate, 8–21 mm long, 10–17 mm wide, rounded and emarginate at apex. Stamens 2, 70–90 mm long, filaments glabrous distally, densely pubescent at base with eglandular trichomes, thecae 13–17 mm long; staminodes (if present) not seen. Style 74–90 mm long, glabrous, stigma unequally 2-lobed, lobes ovate to linear-elliptic to linear-oblanceolate, 2. 5–6 mm long, 1.1–2. 8 mm wide. Capsule 27–40 mm long, 5.5–7. 2 mm in diameter, glabrous, stipe 5–13 mm long. Seeds up to 18 per capsule, 4.5– 5 mm long, 4.3–4. 5 mm wide, surfaces smooth or with irregular ridges.</p>
            <p>PHENOLOGY.— Flowering: April–December; fruiting: June–December. Flowers of Daniel &amp; Wendt 5804 were observed to be fully open after dark.</p>
            <p>DISTRIBUTION AND HABITAT.— Southern Mexico (Chiapas, Veracruz; Fig. 8); plants occur on slopes on limestone (often karstic) in lowland rain forests, lower montane rain forests, and montane rain forests at elevations from 100 to 1500 meters.</p>
            <p>ILLUSTRATIONS.— Figures 4G, H, 16; Miranda (1954:141).</p>
            <p> CONSERVATION.—  Louteridium parayi has an EOO of 2,210 km 2. Plants occur in at least one large protected area in Chiapas, and the EOO includes another small one in Verazcruz. Frequency information on collections varies from locally infrequent to locally frequent. Known occurrences reveal two subpopulations separated by ca. 110 km. Historical landsat imagery (1984 to 2017) via Google Earth Pro (2018) reveals that the habitat of the western subpopulation in the Uxpanapa region of Veracruz has undergone extensive conversion from forested land to local agriculture and pasturage. The same imagery does not clearly show a similar large-scale conversion of forest in the region of the eastern subpopulation in Chiapas. Thus, there are two locations, in one of which a threat is evident. Based on these data, a preliminary conservation assessment of Endangered (EN; B1, a, b; IUCN 2017) is proposed. </p>
            <p> DISCUSSION.—  Although a single specimen was cited in the protologue, and Miranda (1954:125) indicated that the types of plants described in his publication were deposited at MEXU, there are two specimens of Paray &amp; Miranda 7834 in that herbarium. On one of them, “tipo” is written in the same handwriting as the rest of the label (i.e., by Miranda), and in his 1955 note on this specimen Miranda indicated that flowers and part of the inflorescence were lost from the specimen. In his note, he also refers to the isotype, which contains flowers and an inflorescence. Therefore, it seems clear that the sheet bearing “tipo” is the holotype, as indicated above . </p>
            <p> Louteridium parayi is perhaps the most morphologically distinctive species in the genus. It possesses several unusual or unique characteristics: posterior lobe of the calyx subsaccate or with a basal appendage to 2.5 mm, a highly modified inflorescence, fused and basally subsaccate bracteoles, narrow proximal portion of the corolla tube very short to nearly nonexistent, and leathery oblanceolate to obovate leaves. The modified inflorescence of this species appears to be a thyrse, but because the lateral and modified dichasia are alternate (i.e., only one per node of the rachis), the thyrse appears dichotomously branched. The major branches in the inflorescence are interpret- ed as dichasial lateral branches that expand through non-symmetrical sympodial growth into often elongate and somewhat zig-zag “dichasial shoots.” The inflorescence terminates in a dichasium. </p>
            <p>Although no staminodes were seen in several dissections of corollas, it is possible that one or more small appendagelike staminodes could not be discerned among the dense trichomes at the base of the filaments. Indeed, an aberrant bud with extra corolla lobes possessed three fully formed stamens.</p>

            <p>PHENOLOGY.— Flowering and fruiting: August–March.</p>
            <p>DISTRIBUTION AND HABITAT.— Southern Mexico (Chiapas), Guatemala (Fig. 10); plants occur in wooded ravines in montane rain forests on the Pacific versant at elevations from 600 to 2000 m.</p>
            <p>ILLUSTRATION.— Figure 4F.</p>
            <p> LOCAL NAME.— “palo de agua,” (Quarles  van Ufford 137). </p>
            <p> CONSERVATION.—  Louteridium purpusii has an EOO of 944 km 2. Two prominent threats are evident throughout most or all of its known distribution, coffee agriculture and volcanic eruptions. Numerous active volcanos lie within and adjacent to the entire EOO of this species. Most of the occurrences of the species are within the prime growing elevations (i.e., 900 to 1800 m) for  Coffea arabica L., and within two important coffee-growing regions (the Soconusco region of Chiapas, Mexico and the departments of San Marcos and Quetzaltenango in Guatemala). Mexico and Guatemala are two of the top 10 coffee-producing countries in the world (Anonymous 2003, 2018). Increasing demand for coffee worldwide (e.g., Lorenzetti 2016) has or could result in increased conversion of natural vegetation in the EOO of this species to agriculture. Thus, coffee production would appear to be the more immediate threat to  L. purpusii . However, based on either threat, there would appear to be a single location for the species. A preliminary conservation assessment of Endangered (EN; B1, a, b; IUCN 2017) is proposed for this species. </p>
            <p> DISCUSSION.— This species resembles some plants of  L. mexicanum (see discussion under that species), but differs by its more obovate leaves and pubescence. Additional morphological tendencies that distinguish these species include the more racemose (vs. thyrsoid) inflorescences of  L. purpusii (with dichasial peduncle lengths of 0 to 2 (vs. 1 to 22) mm; the caducous bracteoles (vs. usually persistent in  L. mexicanum ); and the generally longer styles (85 to 92 vs. 72 to 85 mm long), capsules (22 to 30 vs. 16 to 24 mm long), and capsular stipes (3 to 3.5 vs. 1 to 2 mm long). The distributional ranges of these two species are not known to overlap and are restricted to different versants of Mexico and Guatemala. </p>

            <p> PHENOLOGY.— Flowering: March–June, September, December; fruiting: March–April, September. Dressler (s.n.) notes that flowers are nocturnal. Richardson (1972) observed flowers of  L. tamaulipense over 14 hours (from 18:00 to 08:00) in September of 1969. He noted: 1) that corollas began opening at sunset and falling in the early morning; 2) the lack of a floral scent; 3) that no nectar was found in the gibbous throat of corollas; 4) the nectary had an intensely sweet taste; and 5) hummingbirds visited flowers at dusk and in the early morning. </p>
            <p>DISTRIBUTION AND HABITAT.— Northeastern Mexico (Tamaulipas; Fig. 8); plants occur on rocky limestone slopes in “tropical semi-evergreen and evergreen forest” (Richardson 1972) at elevations from 340 to 560 (to 1400) meters. The vegetation at collection sites has been characterized on specimen labels as wet forest, cloud forest, and “selva mediana subperennifolia.”</p>
            <p> CONSERVATION.—  Louteridium tamaulipense is a local endemic that is known in the vicinity of the Sierra de Guatemala (= Sierra de Cucharas) in the northern Sierra Madre Oriental of Tamaulipas, where its known distribution (EOO = 43 km 2) is confined to the Reserva de la Biosfera El Cielo. Valiente B. et al. 285 noted that the species was locally very abundant. Several threats have been noted for the biosphere reserve, including: unplanned agricultural and forestry exploitation still being undertaken, overgrazing by livestock, increases in population density in surrounding buffer zones, poorly regulated eco-tourism, and poaching (Anonymous 2007). Most (or all?) of the collections have been made in the buffer zones outside of the two core areas (in which most human travel and exploitation are prohibited) of the reserve. The buffer zones, including the EOO, include roads, villages, and tourist facilities. However, historical landsat images (2005 to 2016) via Google Earth Pro (2018) reveal relatively little change in vegetation cover in the EOO. Thus, based on current knowledge of the species, it is not known to qualify for a threatened category in spite of its very small EOO. Based on the information summarized above, the species is provisionally assessed as Near Threatened (NT). </p>
            <p> DISCUSSION.— Richardson’s (1972) observations on floral phenology and visitation are very similar to those noted above for  L. dendropilosum in Oaxaca.  Louteridium tamaulipense shows some similarities to  L. costaricense , and can be distinguished from that species of southern Central America by characters in the following couplet: </p>
            <p> 1a. Corolla externally pubescent with glandular trichomes 0.1– 0.5 mm long and eglandular trichomes 0.1– 1 mm long, lower lip 13–22 mm long; capsule 27–35 mm long, glabrous, stipe 7–12 mm long; inflorescence peduncles, rachis, peduncles of dichasia, and abaxial surface of bracts and bracteoles glabrous (or the bracts and bracteoles sometimes glandular-punctate but lacking elongate trichomes); bracts and bracteoles persistent................  L. costaricense</p>
            <p> 1b. Corolla externally puberulent with glands to 0.1 mm long, lower lip 27–31 mm long; capsule 22–25 mm long, pubescent with glandular trichomes 0.05– 0.2 mm long, stipe 1–4 mm long; inflorescence peduncles, rachis, peduncles of dichasia, and abaxial surface of bracts and bracteoles pubescent with glandular trichomes 0.1– 0.3 mm long; bracts and bracteoles caducous..................................................................
