A New Name and a New Species in Matelea (Apocynaceae, Aselepiadoideae) from Brazil

摘要

The new name Matelea endressiae Goes & Fontella is proposed to replace Conolobus cordatus Malme from Brazil. A new species. M. demuneri Goes & Fontella, from Fspirito Santo State, Brazil, is described and illustrated. Matelea demuneri is similar to M. endressiae and M. marilima (Jacquin) Woodson subsp. cearensis (Malme) Fontella, but it is distinguished from the (irst by its shorter pedicel and corolla tube, pubescent corona, and lollicles with short projections, and from the second by its mixed indumentum, inflorescence with peduncle, green-purple corolla, rounded 5-lobed corona, shorter pollinia, and lollicles with short prickles.
