9E1387AAFF97247BC6492E66FAD0F924.taxon	distribution	DISTRIBUTION. — Known only from Paraguay and known only from its type-material. O’Donell (1950 a) mentioned that there was a paratypus in SI and LIL herbaria, but he failed to cite the material and it has not been located so far. Among the species studied here, this is the only one that has not been recorded from Brazil.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

9E1387AAFF97247BC6492E66FAD0F924.taxon	discussion	REMARKS Distinguished by its herbaceous habit with scandent stems, narrowly elliptical leaves with simple trichomes that are thickened at base mixed with forked trichomes, and monochasial inflorescences, J. anomala is difficult to distinguish from J. guaranitica, differing only in the type of indumentum and bracteole size. The fact that J. anomala is known through a single collection makes it difficult to ascertain whether it represents a variant of J. guaranitica with longer bracteoles and without stellate trichomes on its stems.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

9E1387AAFF97247EC43C2EA7FA9BFD66.taxon	distribution	DISTRIBUTION. — Jacquemontia evolvuloides has widespread distribution ranging from USA (Arizona) to South America (Robertson 1971; Austin & Cavalcante 1982). In Brazil, it occurs mainly in Cerrado, Caatinga, and anthropic areas. It is uncommon in the Amazon and in Atlantic Rainforest.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.) Meisn. and related species (Convolvulaceae). Adansonia 39 (2): 149-166, DOI: 10.5252/a2017n2a6, URL: http://www.bioone.org/doi/10.5252/a2017n2a6
9E1387AAFF97247EC43C2EA7FA9BFD66.taxon	discussion	REMARKS Jacquemontia evolvuloides varies widely in the habit, leaf shape and density of the indumentum. Regarding the habit, mature plants with secondary growth only at the base of stems grow into subshrubs with voluble distal stems, but sometimes the plant can flower when very young, with almost erect habit. We observed a similar trend in other Convolvulaceae species, such as J. nodiflora (Desr.) G. Don, J. tamnifolia (L.) Griseb., Ipomoea nil (L.) Roth., and I. quamoclit L. Density of the indumentum varies between individuals from dense to sparse. Stem trichomes may be only stellate, 3 - radiate, with equal to subequal rays; intermixed 3 - radiate trichomes with unequal rays (central ray longer than the lateral rays), or a combination between forked and rarely simple, basally thickened trichomes (Fig. 2). Regardless of the fact that glandular trichomes are typical of J. evolvuloides, even these are lacking in some specimens as also observed by Robertson (1971). Leaf trichomes are stellate, 3 - radiate, with equal or subequal rays, sometimes with glandular margin, and the density is very variable. Leaf size varies between 1 to 5.5 cm long and the shape is generally ovate with cordate base, however they can also be truncate or obtuse at base. This morphological variation follows the wide distribution of this species in America. Brandegee (1903) observed that more robust plants grow in environments with abundant rainfall and in the shade (as those formerly recognized as J. agrestis). The material G 00222066 was used to prepare the figure that appears in the original description (Moricand 1838) and was chosen as the lectotype of Ipomoea evolvuloides. Jacquemontia agrestis was recognized by Meisner (1869), who distinguished it from J. evolvuloides by its herbaceous stems, denser indumentum and larger leaves (2 - 4 cm long) with deeply cordate base. Austin (1982) and O’Donell (1953) already mentioned the overlapping characters between J. agrestis and J. evolvuloides. Meisner (1869) recognized three varieties of J. evolvuloides: a) Jacquemontia evolvuloides var. longepedunculata, an illegitimate name based on the same type of Ipomoea evolvuloides, McDonald (1993) had previously synonymyzed this variety under J. agrestis; b) Jacquemontia evolvuloides var. brevipedunculata is synonymous with J. sphaerostigma, as annotated by O’Donell in 1952 on the holotype (BR), but not published; c) Jacquemontia evolvuloides var. tweediei is synonymous with J. heterotricha, as recognized by O’Donell (1950 b). Chodat & Hassler (1905) and Hassler (1911) described varieties and forms such as J. evolvuloides var. grandiflora f. albiflora, J. evolvuloides var. grandiflora f. tomentosula and J. evolvuloides var. grandiflora f. hirsutula, causing great confusion pertaining the status of these taxa. The analysis of the type materials brought us to the conclusion that these are all synonyms of J. evolvuloides. Meisner (1869) also recognized Jacquemontia racemosa, and distinguished it from J. evolvuloides by cordate-ovate leaves with ondulate margins and racemose inflorescence. Study of the type material revealed a monochasial inflorescence (the racemes on the sheet actually belonging to a Lamiaceae stem around which Jacquemontia is entwined). We do not consider the characters proposed to separate J. racemosa and J. agrestis distinct enough to grant them recognition at specific level and propose their synonymization under J. evolvuloides. Moreover J. racemosa is an illegitimate name, as Meisner (1869) failed to combine C. breviacuminatus into Jacquemontia breviacuminata and created a new epithet instead (Staples et al. 2015). The name Jacquemontia decumbens is also considered a synonym of J. evolvuloides. O’Donell (1950 c) used its prostrate habit, shorter and very sparse glandular trichomes, leaves not deeply cordate, and larger corollas as distinctive features, but even then, he was not totally convinced that this taxon was a good species, commenting that it might be a variety or a form. Anyway, these characters have proven to be too variable and insufficient to deserve taxonomic recognition.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

9E1387AAFF922474C4EF2B60FDA7FBE7.taxon	discussion	REMARKS Jacquemontia fruticulosa is morphologically similar to J. heterotricha, as both have sub-shrubby habit with either erect or scandent stems, stellate trichomes (3 - radiate, with subequal rays mixed with 3 - radiate with unequal rays), wide to narrowly ovate leaves, and monochasial, few flowered inflorescence. On the other hand, Jacquemontia fruticulosa can be distinguished by the tomentose indumentum, longer bracteoles (5 - 8 mm long), and shorter peduncles (up to 6 mm long) while J. heterotricha has sparse indumentum, shorter bracteoles (1.5 - 2.5 mm long), and longer peduncles (1 - 2 cm long). Hassler (1911) created several varieties and forms distinguished by the density of their glandular hairs and leaf size, however, upon examining abundant material, we consider that these characters are highly variable amongst and within populations, and we opt to synonymize them.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

9E1387AAFF982474C64D2CE1FCD7F862.taxon	discussion	REMARKS According to Hassler (1911), J. guaranitica differs from J. evolvuloides by its seeds measuring up to 3.5 mm long, while J. evolvuloides seeds are up to 2.2 mm long. We also found that venation on leaves, ciliate margins and glandular trichomes are good characters to separate the species. Jacquemontia guaranitica is also very close to J. anomala and J. warmingii, all of them with herbaceous habit and scandent stems up to 50 cm long, turning reddish in sicco, sparsely hirsute stems and leaves, lamina elliptic and with 2 - 3 pairs of eucamptodromous veins.

9E1387AAFF9A2476C7982A83FB14F885.taxon	discussion	REMARKS Jacquemontia sphaerostigma has herbaceous habit and climbing stems, dense inflorescences and four distinct types of trichomes: stellate 3 - radiate with subequal rays; stellate 3 - radiate with unequal rays; forked (rarely simple); and glandular trichomes (Fig. 2). With the similar indumentum to J. evolvuloides, J. sphaerostigma is distinguished with basis on its umbelliform to corymbiform dichasium, while J. evolvuloides has lax monochasial. Choisy (1838) observed that Convolvulus sphaerostigma Cav. should be transferred to Jacquemontia but he renamed it as J. hirsuta, creating an illegitimate name. Rusby (1899) subsequently made the correct combination. We considered Jacquemontia laxiflora as synonym of J. sphaerostigma because slightly lax inflorescence, non-glandular trichomes, and corolla 12 - 15 mm long are characters also found in some specimens of J. sphaerostigma.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

9E1387AAFF9A2469C4EA2F07FD1EFC26.taxon	discussion	REMARKS Jacquemontia warmingii is allied to J. anomala and J. guaranitica, and the distinguishing characters are presented in Table 1. Hassler (1911) had already suggested that Ipomoea prostrata Meisn. probably belonged to the genus Jacquemontia, but he did not propose a new combination. When transferring Ipomoea prostrata (1869) to Jacquemontia, O’Donell (1950 c) correctly proposed the replacement name J. warmingii (1950), according to article 11.4 (Mcneill et al. 2012). The name Jacquemontia was previously occupied by J. prostrata Choisy (1845).	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

However, this species is not part of the species group studied here, as its protologue clearly states that its calyx has outer oblong sepals smaller than the inner ones, and that the inner sepals are obovate, with abrupt acuminate apex.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)

However, J. hispida is unlikely to belong to the informal group studied here, because its sepals are described as cordate at base.	en	Pastore, Mayara, Moreira, André Luiz da Costa, Cavalcanti, Taciana Barbosa, Simão-Bianchini, Rosângela (2017): A taxonomic study of Jacquemontia evolvuloides (Moric.)
