Grewia L. subg. Vincentia (Benth.) Capuron, stat. nov., as proposed by CAPURON (1963), is revised for Madagascar and the Comoro Islands, according to the manuscripts and other notes of the late R. CAPURON. Ten species are recognised and half of these are new: G. lapiazicola Capuron, G. luteiflora Capuron, G. meridionalis Capuron (comprising var. antandroy Capuron and var. meridonalis), G. sambiranensis Capuron and G. suarenzensis Capuron. Grewia bojeri Mabb. is a new name for G. lancifolia (Bojer) Baron non Roxb. As amendments to CAPURON (1963), Christiana africana DC. is typified and a new combination, Pseudocorchorus rostratus (Danguy) Mabb., proposed.
