352387B7467FFFE1FF381089FED1FC37.taxon	discussion	Discussion: — Anthurium filamatamaense is probably closest to A. churchilleorum Croat (in Croat et al. 2013: 36) which shares a similar blade shape with a long-acuminate apex, but the latter species differs by having leaf blades with a narrowly parabolic sinus (vs. sinus hippocrepiform for A. filamatamense), drying dark green to slightly lighter green (vs. dark brown), the upper surface densely and conspicular granular and more densely short pale-lineate, a more conspicuously glandular-punctate lower surface, basal veins with posterior rib 1.0 cm long (vs. 5 cm long) as well as by its maroon spadix (vs. lavender spadix). Anthurium filamatamaense is also similar to A. formosum which differs in being a much more robust plant, having many persistent intact cataphylls (vs. with persisting semi-intact cataphylls for A. filamatamaense), blades prominently granular on both surfaces as well as by having usually 2 – 3 pairs of basal veins free to the base (vs. 1 pairs of basal veins free to the base). Another species in the region of the type in adjacent Panama that is similar is Anthurium kareniae Croat (in Croat et al. 2013: 47), which differs by having light brown-drying leaves (vs. dark brown) with closed sinus, 2 pairs of free basal veins (vs. 1 pairs of basal veins free to the base) and collective veins arising from the 1 st pair of basal veins (vs. collective veins arising from the 3 rd pair basal veins). In the Lucid Anthurium Key (Haigh et al. 2009) A. filamatamense tracks to A. huixtlense which ranges from Mexico to Nicaragua which differs by having shortly acuminate blades (vs. abruptly caudate acuminate blades for A. filamatamense) with the collective vein arising from one of the lowermost primary lateral veins or from the first basal vein (vs. collective veins arising from the 3 rd pair basal veins); A. kamemotoanum Croat (1986: 120) which differs by having blades with the collective veins arising from the 1 st pair of basal veins (vs. collective veins arising from the 3 rd pair basal veins), inflorescences with prominently naviculare spathe (vs. oblanceolate spathe) and red-violet spadix at anthesis (vs. lavander spadix) and A. obtusilobum which differs by having a pale green to white spreading to reflexed oblong-elliptic spathe (vs. a white to weakly lavender erect oblanceolate spathe) and cream-colored spadix at anthesis (vs. lavender spadix).	en	Ortiz, Orlando O., Croat, Thomas B.

352387B74679FFE2FF381283FEB1FC37.taxon	distribution	Distribution: — This species is endemic to Panama, known only from the type locality in Veraguas province, Santa Fe, Panama. Habitat and Ecology: — Anthurium lasabanetaense grows at 1100 m in a Montane rain forest life zone according to the classification of Holdridge et al. (1971). According to Cáceres-González & Ibáñez (2014), the vegetation of La Sabaneta resembles a highland savanna, dominated by Colpothrinax aphanopetala Evans (2001: 189) and abundant trees of the families Clusiaceae, Myrsinaceae, Ericaceae and Araliaceae. Phenology: — Two specimens examined flowered in February and October, but two other specimens were fruiting in July and September. This species maybe flowers and fruits throughout the year, but further investigations are required to determine exact flowering and fruiting times. Conservation status: — This species is notable for its reduced geographical range. Cáceres-González & Ibáñez (2014) mention that compared to other sites throughout the country, the La Sabaneta region in Santa Fe National Park is a place with special and unusual ecological characteristics. We suggest this species be considered in the CR B 2 ab (iii) category according to the IUCN Red List Criteria (IUCN 2001).	en	Ortiz, Orlando O., Croat, Thomas B.

352387B74679FFE2FF381283FEB1FC37.taxon	discussion	Discussion: — In Panama Anthurium lasabanetaense could be confused only with A. obtusilobum Schott, A. sanctifidense Croat (1981: 334), A. sapense Croat (1986: 178) and A. globosum Croat (1986: 105), all of which have similar blade shapes and whitish spathes. Anthurium obtusilobum also differs by blades with collective veins arising from one of the lowermost basal veins (vs. collective veins from first pair of basal veins), basal veins ca. 8 pairs (vs. 4 – 5 pairs of basal veins) and inflorescences with reflexed, oblong-elliptic spathes at anthesis (vs. erect, ovate-subcordate and naviculiform spathes); A. sanctifidense differs by broadly ovate blades with lower surfaces moderately paler and glaucous when fresh (vs. ovate-sagittate blades, not glaucous on lower surface for A. lasabantense), ovate to lanceolate spathes at anthesis (vs. ovate-subcordate, naviculiform spathes) and infructescences with purplish spadices and violet purple or orange berries (vs. infructescences with reddish spadices with red berries); A. sapense differs by ovate-triangular blades (vs. ovate-sagittate blades), entirely white spathes without red veins at anthesis (vs. white spathes with many red veins), purplish berries (vs. red berries) and A. globosum differs by inflorescences at anthesis with green spathes (vs. white spathes) and globose spadices (vs. cylindroid spadices). In the Lucid Anthurium key (Haigh et al. 2009) A. lasabanetaense tracks to Anthurium roseospadix Croat (1986: 170) which differs by inflorescences with shorter, 7.5 – 18.0 cm long peduncles (versus peduncles 44.0 – 53.5 cm long), violet-purple spadices at anthesis (vs. creamy-white spadices) and whitish berries (vs. red berries).

Eponymy: — The species epithet suffusum is from the Latin “ suffusus ” meaning “ tinged ” referring to the second color tinged along the margins of the inside of the spathe.	en	Ortiz, Orlando O., Croat, Thomas B.

352387B74671FFEAFF38105AFA37FF3B.taxon	distribution	Distribution: — Anthurium suffusum is endemic to Panama, known only from Cerro Jefe in Panamá Province. Habitat and Ecology: — This species grows at 700 m in a Premontane rain forest life zone according to Holdridge et al. (1971). Phenology: — Found in flower in May. Further investigations are required to determine the exact phenology. Conservation status: — Anthurium suffusum should be listed as Data Deficient (DD) according IUCN Red List criteria (IUCN 2001).	en	Ortiz, Orlando O., Croat, Thomas B.

352387B74671FFEAFF38105AFA37FF3B.taxon	discussion	Discussion: — Anthurium suffusum could be confused with A. formosum and A. sanctifidense, all of which have similar leaf blades and spadix shape. Anthurium formosum also differs by petioles subterete, sulcate adaxially (vs. petioles totally terete, lacking sulcus), white or violet spathes (vs. spathes creamy white with the inner surface tinged with lavender along the margins) and violet-purple spadix at anthesis (vs. spadix cream-colored); A. sanctifidense differs by having blades drying dark brown with short pale-lines in the upper surfaces (vs. blades drying brownish green and lacking short pale-lines in the upper surfaces), longer (7.0 – 36.0 cm long) peduncles (versus peduncles shorter 4.0 cm long) and totally pale green to greenish white or white spathes (vs. spathes creamy white tinged with lavender). In the Lucid Anthurium key (Haigh et al. 2009) A. suffusum tracks to A. buganum Engler (1898: 425), which differs by having all the basal veins free to the base (vs. not all basal veins free to the base, only first or second pairs of basal veins free) and the sinus much narrower; to A. fusiforme Croat (1986: 102), differing by its fusiform spadix (vs. spadix cylindroid-fusiforme) and collective veins arising from the primary lateral veins (vs. collective veins arising from the first pair of basal veins); to A. hoffmannii, differing by having a pinkish or greenish yellow spadix (vs. spadix cream-colored) and with the upper surface densely paler short-lineate (vs. upper surface lacking pale short-lines) and to A. obtusilobum, differing by having blades which are conspicuously short-pale lineate on the upper surface and have the collective veins arising from the lower basal veins (vs. collective veins arising from the first pair of basal veins).	en	Ortiz, Orlando O., Croat, Thomas B.
