Abstract

A new species of Convolvulaceae, Jacquemontia revoluta Simão-Bianchini, is described and illustrated. This species is known only from the rocky slopes of Serra do Cipó (Minas Gerais, Brazil), where it is associated with ant nests. The taxon is distinct in the genus by the linear leaves with revolute margins and 5-stellate (almost scale-like) trichomes. In addition to the description and illustration, comments on its probable relationships, habitat, and distribution are presented. Jacquemontia revoluta is probably related to J. linoides (Choisy) Meissner; both species are rare.
