Distribution

Africa: present Asia: present
A palaeotropical genus of 10 species, 8 in Africa (subg. Microdesmis), 2 in Asia (subg. Ganitrocarpus).

Taxonomy

The genus is divided into two subgenera, subg. Microdesmis has 5 stamens and non-apiculate connectives; subg. Ganitrocarpus has 10 stamens. The second character for this subgenus, the apiculate connective, is redundant, because M. magallanensis lacks this extension of the connective.
