A taxonomic revision of Mallotus section Polyadenii (Euphorbiaceae)

Mallotus sect. Polyadenii comprises eight species. It includes the former genus Coccoceras. Mallotus leucodermis var. puberulus, endemic to the Solomon Islands, is recognised on the species level as M. puber. Mallotus anisopodus, from Indochina, is synonymised with M. plicatus from Myanmar. The identification of species is difficult, especially of M. leucodermis and M. muticus. The two species are partly sympatric and only pistillate flowers or fruits provide reliable characters; specimens with staminate flowers are very difficult to identify.
