Abstract in another language

A taxonomic revision of Sabicea subgenus Anisophyllae (Rubiaceae), a group restricted to Central and East Africa, is presented here. This work, based on a study of herbarium specimens and field observations in Cameroon and Gabon,includes a survey of the morphological features of the group, a key to the species, descriptions of all the taxa, and IUCN conservation status assessments. Fifteen species are recognised, four of which are described as new (Sabicea mapiana , S. ndjoleensis , S. parmentierae , S. sciaphilantha ), three former varieties are raised to species rank (S. crystallina , S.jacfelicis , S. tersifolia ), and one species previously sunk into synonymy is restored (S. bequaertii ). Two new infraspecific taxa are also described, Sabicea crystallina subsp. engongensis and S. sciaphilantha subsp. hirsuta . The group has its center of diversity in Gabon, where 10 of the 15 species occur, three of them being endemic to the country.
