Kew Bulletin Aims and scope Submit manuscript

Summary

A revision of Octoknema Pierre is provided, based on morphological data gathered from a study of herbarium specimens and observations in the field. Fourteen species of Octoknema are recognised including six new species: O. bakossiensis Gosline & Malécot, O. belingensis Gosline & Malécot, O. chailluensis Malécot & Gosline, O. kivuensis Gosline & Malécot, O. mokoko Gosline & Malécot and O. ogoouensis Malécot & Gosline. Data are given for four additional poorly known taxa (Octoknema species A, B, C and D).
