Lycianthes pringlei was first described (in the genus Solanum) in 1895. Since that initial publication, a description of the species has been included in just one taxonomic work, Georg Bitter's 1919 monograph on the genus. In both works, the species is described as a perennial herb, a misconception that is repeated on the labels of some of those who have collected the species. Lycianthes pringlei is a shrub, often present in low population densities, with calyces and seeds that are uncommon in the genus. This article provides a new description for the species, illustrations of species characteristics, and seed photos.
