Abstract

Eumachia brevipedunculata is a newly-identified species of the tribe Palicoureeae of Rubiaceae from Yunnan, China. It is morphologically similar to E. straminea, but differs by its smaller stipules, shorter petioles, smaller leaf blades, reduced inflorescences with shorter peduncles, axes and pedicels, longer calyx lobes, yellow-green flowers with shorter corolla tubes and shorter anthers. This species is widely found in southern Yunnan, but has long been misidentified as Psychotria. We clarify its taxonomic status and provide a description and illustration here.
