Abstract

Matelea atrostellata Rintz (Apocynaceae, Asclepiadoideae), a new species from Trans-Pecos, Texas, U.S.A., is described and illustrated. This species is very similar vegetatively to M. producta (Torrey) Woodson and M. texensis Correll, but is readily distinguished floristically by its rotate corolla and its nearly black corona. Both M. producta and M. texensis have campanulate corollas and very pale green or white coronas. This is the fifth species of Matelea Aublet to be recorded from Brewster County, Texas.
