As part of the integrative systematic studies on the tribe Maleae, a synopsis of the expanded is presented, recognizing 45 species. Three new forms were validated: R. bengalensis f. contracta B.B.Liu & J.Wen, R. bengalensis f. intermedia B.B.Liu & J.Wen, and R. bengalensis f. multinervata B.B.Liu & J.Wen, and four new combinations are made here: R. bengalensis f. angustifolia (Cardot) B.B.Liu & J.Wen, R. bengalensis f. gigantea (J.E.Vidal) B.B.Liu & J.Wen, (W.B.Liao, Q.Fan & S.F.Chen) B.B.Liu & J.Wen, and (Hook.f.)
