Lasiodiscus, commonly known as red-hair bushes, is a small plant genus in the family Rhamnaceae. It is endemic to Africa and its adjacent islands.

Contents

Description

The small trees have opposite, often asymmetric leaves. As with Colubrina, the flower ovaries are surrounded by a nectariferous disc that fills the receptacle.

Habitat

They regularly occur in the understorey of tropical forests, or alternatively in swamp forest. One species, L. rozeirae, is limited to mountain forest understorey.

Relationships

Lasiodiscus is morphologically similar to Colubrina, which occurs in the Neotropics, Asia and Afrotropics, but preliminary molecular analysis failed to group them as nearest relatives.

There are 9 accepted species:

  • Lasiodiscus chevalieri Hutch. –
  • Lasiodiscus fasciculiflorus Engl. – Sierra Leone to Nigeria, w Cameroon and D.R.C.
