Scale bars: a, d, g, j = 5 mm; b, c, e, f, h, I, k, l = 2 mm. Etymology— The epithet hernandioides is probably related to the similarity with the frequently peltate or subpeltate leaves of the genus Hernandia ( Hernandiaceae ). Distribution— It occurs in the U. S. A. , Mexico , the West Indies, Venezuela , Colombia , Bolivia , Paraguay , Argentina , and Brazil . In Brazil , the species is found in all regions, but it is rare in the northeastern region. Note— Wissadula hernandioides is very similar to W. amplissima , but is distinguished by the absence of simple and long trichomes on branches and velutinous indumentum on the adaxial surface of the leaves this species Kuntze (1898) proposed Abutilon amplissimum var. subpeltatum based on the overlapping basal leaf lobes and considered Sida hernandioides a synonym. Chodat and Hassler (1885 –1902) examined two collections from Paraguay and proposed W. periplocifolia var. suborbiculata and var. cordata based on the same leaf characteristic described above. Fries (1908) , after analyzing both collections, accepted A. amplissimum var. subpeltatum and reported a characteristic that was not observed before for the taxon: the presence of short, erect and oblique bristles on the pedicel and calyx. Based on these characteristics, Fries (1908) established W. subpeltata , considering the varieties proposed by Chodat and Hassler (1885 –1902) as synonyms. Based on the type material of W. subpeltata (NY and US) and on materials from several localities, we noticed that the presence of lobes on the leaves is not consistent. That is, the same specimen ( Hoehne 2994 , Eugenio 234 ) may have leaves with imbricate lobes or not. On the original plate of W. amplissima , the basal leaves have lobes united to one another. In the protologue of Sida hernandioides , this characteristic was already mentioned as “ folia ..., imbricatocordata , ” together with a good illustration to show it. The presence of simple, long trichomes is a diagnostic character for W. amplissima , and it is also found in specimens with imbricate lobes at the base of the leaves ( Krapovickas 38608, 40195 ). We noticed that the presence of the bristles (= short, simple and thick trichomes) in the peduncle and calyx, as observed by Fries (1908) and confirmed by A. Krapovickas (pers. comm.), is not a consistent characteristic. We did find specimens with bristles in the region of the inflorescence, but many others did not have them. Moreover, the original description based on the type specimen only considered the leaf lobes to characterize A. amplissimum var. subpeltatum , as the presence of bristles may have raised doubts. Another important question is the geographic distribution of W. subpeltata , which overlaps the geographic distribution of W. amplissima . Based on all these considerations, we propose W. subpeltata as a synonym of W. hernandioides . In the protologue of W. hernandioides , the type specimen is originally from Hispaniola (currently Caribbean) and has the initials H. P., which could refer to ‘Hortus parisiensis’ (A. Krapovickas, pers. comm.). However, no material was found in the Paris (P) collection. After consulting Herbarium G, where the type collection was most likely to be, Fryxell (2007a) lectotypified this species, citing L´Héritier’s plate in the protologue (P. Fryxell, pers. comm.). Schumann (1891) considered Sida racemosa Vell. as a synonym of W. hernandioides . However, the Vellozo’s species is a nomen nudum , as it was not described. We accepted this as a synonym because the species illustration presented by Vellozo [1827(1831)] shows leaves with a cordate base and an absence of trichomes on branches.
