| Résumé : | Background - The genus Multidentia Gilli (Rubiaceae-Vanguerieae) includes nine species from tropical Africa. A tenth species, M. saxicola O.Lachenaud & Séné, is here described and illustrated. Methods - Classical methods of herbarium taxonomy have been applied. Key results - Multidentia saxicola occurs in Cameroon and in D.R.Congo; it is only known from two localities about 1,500 km apart. It most closely resembles M. sclerocarpa (K.Schum.) Bridson from Tanzania but differs in the nearly unlobed calyx and lenticellate fruits. It differs from M. dichrophylla (Mildbr.) Bridson in having much larger calyces and fruits and in being a taller tree (12-20 m). Multidentia saxicola is evaluated to be Critically endangered (CR B2ab(iii)) according to IUCN criteria. A key to the central African species of Multidentia is presented. © 2012 National Botanic Garden of Belgium and Royal Botanical Society of Belgium. |
