Abstract

The genus Rupestrea is described to include two species previously described in Miconia. Rupestrea carvalhoana and R. johnwurdackiana are restricted to Campos Rupestres at the northern portion of the Chapada Diamantina in Bahia, Brazil. The genus can be recognized by the dry and indehiscent fruits that may be hydrochorous, and by the orthocampylotropous, monoembryonic seeds, each incompletely divided into two cavities by a septum. The genus is sister to a large clade that includes the capsular-fruited tribes Melastomeae, Microlicieae, and Rhexieae.
