Gyrostipula obtusa Emanuelsson & Razafimandimbison, a new species of Rubiaceae (Naucleeae) from Madagascar, is described and illustrated. The new species differs from its congeners, G. comorensis J.-F. Leroy and G. foveolata (Capuron) J.- F. Leroy, by its obtuse leaves with more densely spaced lateral (secondary) veins and shorter petioles.
