Résumé : | A revision of Bertiera Aublet is undertaken, based mainly on a study of Cameroonian herbarium specimens at BR, BRLU, K, P, SCA, WAG and YA. The morphological features (habit, leaves, stipules, domatia, colleters, flower, fruit and seed characters) of the genus are reviewed and documented. The distribution maps of the species show the characteristic distribution pattern of a strict rain forest genus. The taxonomic part gives keys and complete treatments of species (synonymies, descriptions, distributional data, critical notes). The detailed examination of the specimens resulted in some changes. It is proved that Bertiera globiceps K.Schum. var. bityensis (Wernham) N.Hallé and Bertiera racemosa (G.Don) K.Schum. var. dewevrei (De Wild. & Th.Dur.) N.Hallé are not worth varietal distiction. On the other hand, Bertiera subsessilis Hiern var. congolana N.Hallé needs to be returned to its specific status (Bertiera congolana De Wild. & Th.Dur). Two species are new records for the Cameroon flora: Bertiera congolana De Wild. & Th.Dur. and Bertiera arctistipula N.Hallé. |
