Roscheria is an endangered, monotypic genus of flowering plant in the palm family. The genus is named for Albrecht Roscher, a 19th-century German explorer, and the epithet for its single species R. melanochaetes derives from Latin and Greek meaning 'black' and 'bristle', alluding to the spines covering the trunks.
