Etymology— Grisebach (1879) most likely used the epithet wissadifolia as a reference to the similarity between the leaves or fruits and those of the species of Wissadula when it was described in the genus Abutilon . Distribution— The species is found in Bolivia , Argentina , and Brazil . It is recorded for the first time in Brazil where it is restricted to the State of Mato Grosso do Sul . In Bolivia and Argentina , it occurs in a region known as chaco. Note— Wissadula wissadifolia is characterized by leaf blades with a lobate-imbricate or cordate base, crenate to serrate margin, adaxial surface with simple, glandular, fasciculate and multiradiate trichomes, and branches, petioles and inflorescences with simple and very long trichomes. It is very similar to W. setifera , but the latter has smaller leaf blades and a different type of indumentum.
