Abstract

Euploca decorticans, is here described and illustrated as a new species from a heretofore poorly collected mountain area in Goiás state, Brazil. It is most morphologically similar to E. salicoides, one of the most widely distributed taxa of the genus in Brazil but differs from that species in several features related to habit (height and growth aspect), leaves (shape, trichome types, and venation pattern), flowers (size, corolla shape, length, color), inflorescence (length), fruits (diameter and trichome types) and nutlets (shapes), among other features. We include a distribution map besides photos and drawings of the new species, and we also discuss its conservation status.
