Croton tranomarensis var. minor Leandri, Ann. Mus. Colon. Marseille, ser. 5, 7(1): 61. 1939

Type.

Madagascar. Prov. Toliara: Anosy Region, Ambovombe, Behara , 9 Jan 1931, R. Decary 8370 (holotype: P [P00133390]!; isotypes: K [K001040391]!, TAN [TAN000545]) .

Notes.

The leaves of the type of this variety are too small to conform to Croton meridionalis (for which C. tranomarensis is a synonym). Radcliffe-Smith (2016) expressed doubt that it belonged here, but he did not know where else to place it other than to suggest that it may be close to C. salviformis (presumably because of the small leaves and venose pistillate sepals). However, the holotype appears to have entirely pistillate inflorescences, suggesting that the plants may be dioecious. If so, it may correspond to an apparently undescribed species that we have also found south of Ranopiso at Mt. Vohitsiandriana in Toliara Province.
