Revision of the Malvaceae-Grewioideae ("Tiliacées" p. p.) of Madagascar and the Comoro Islands. IV. Grewia subg. Burretia (Hochr.) Capuron.

Grewia L. subg. Burretia (Hochr.) Capuron is revised for Madagascar and the Comoro lslands. Fourteen species are recognised and five of these are new: G. erythroxyloides Capuron, G. monantha Capuron ex Mabb., G. ribesioides Capuron & Mabb., G. sahafariensis Capuron & Mabb., and G. tsiandrensis Capuron. There is one new combination, G. microcyclea (Burret) Capuron & Mabb., and new infraspecific taxa are G. microcyclea f. albida Capuron and G. flavicans Boivin ex Baill. var. boinensis Capuron. Attention is drawn to the remarkable floral variation in G. brideliifolia Baill.
