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.

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 View FIG ). 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 G00222066 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 byMeisner (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 (1950b).

Chodat & Hassler(1905) andHassler (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 (1950c) 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.
