Etymology— The epithet setifera derives from the Latin word seta, referring to the simple, long and thickened trichomes found on the branches, petiole and calyx.
Distribution— It occurs in Bolivia, Paraguay, Argentina and Brazil. This is the first record of W. setifera for Brazil where it occurs only in the State of Mato Grosso do Sul. The species was previously known only in Bolivia, Paraguay, and northeastern Argentina.
Note— It is characterized by the delicate appearance of its habit and, mainly, by the abundance of simple trichomes, these are very long on the branches, petioles and calyx. It is closely related to W. decora , but the latter does not have simple, long trichomes on the branches, petioles and calyx. However, based on its trichomes, W. setifera resembles W. wissadifolia , but differs in the absence of clasping lobes at the base of leaves and the presence of a few simple long trichomes on the adaxial surface of the leaves.
