A new species of Oreocarya (Boraginaceae), O. worthingtonii Sivinski, is described from the Brokeoff Mountains branch of the Guadalupe Mountain range in Eddy and Otero counties, New Mexico. It is similar to Oreocarya oblata (M.E. Jones) J.F. Macbr. in pubescence, homostyly and globular, roughened fruits, but differs in its slender stems with linear leaves, subcapitate inflorescence and finely tuberculate nutlets. Specimen photos and a key to Oreocarya species with globular fruits and roughened nutlets from the northern Chihuahuan Desert are also presented.
