Schizocarp 0.8–0.9 cm diam, 4(–5) mericarps, 8–9 × 3–4 mm, spines < 1 mm long, constriction inconspicuous, glabrescent to puberulous, trichomes glandular; seeds 3, < 2 mm long, hilum puberolous, trichomes simple.
Distribucion y Habitat
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.

Nombre Vulgar y Usos
Tipo y Observaciones
Material Tipo: Basónimo: Sida hernandioides L'Hér.
Observaciones: Etymology—The epithet hernandioides is probably related to the similarity with the frequently peltate or subpeltate
leaves of the genus Hernandia (Hernandiaceae).
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.
