Lasiodiscus is a small plant genus in the family Rhamnaceae, endemic to Africa and its adjacent islands. The small trees have opposite, often asymmetric leaves. They regularly occur in the understorey of tropical forests, or alternatively in swamp forest. One species is limited to mountain forest understorey. Lasiodiscus is morphologically similar to Colubrina but preliminary molecular analysis failed to group them as nearest relatives.[1]
There are 9 species:
- Lasiodiscus chevalieri Hutch.
- Lasiodiscus fasciculiflorus Engl.
- Lasiodiscus holtzii Engl.
- Lasiodiscus mannii Hook. (central Africa)
- Lasiodiscus marmoratus C.H. Wright
- Lasiodiscus mildbraedii Engl. (African tropics, locally along African east coast from South Africa)
- Lasiodiscus pervillei Baill. (Africa, Madagascar, Mauritius, Réunion and Comores)
- L. p. pervillei (widespread in Madagascar)
- L. p. ferrugineus (Verdc.) (local in east Africa, Vulnerable)
- Lasiodiscus rozeirae A.W. Exell (São Tomé, Gulf of Guinea, Vulnerable)
- Lasiodiscus usambarensis Engl. (Usambara mountains, locally to Zimbabwe)
