Abstract:

Revision of the African genus Sherbournia (Rubiaceae, Gardenieae). A revision of Sherbournia G.Don is given, based mainly on a study of the herbarium specimens at BATA, BM, BR, BRLU, K, LBV, MO, P, SCA, WAG and YA. The general part gives a survey of the history of the genus; the morphological features (habit, leaves, stipules, domatia, flower, fruit characters) of the genus are reviewed and documented. The distribution maps of the species show the characteristic distribution pattern of a strict Guineo-Congolian genus. The taxonomic part gives keys and complete species treatments (synonymies, descriptions, distributional data, critical notes). The detailed examination of the specimens resulted in one novelty: Sherbournia batesii subsp. kivuensis Pauwels & Sonké. Some taxonomic changes are made: Sherbournia streptocaulon (K.Schum.) Hepper var. situtunga N.Hallé is proved to be synonymous with Sherbournia streptocaulon (K.Schum.) Hepper; Sherbournia bignoniiflora (Welw.) Hua var. brazzaei N.Hallé, Amaralia palustris Wernh., Amaralia ekotokicola Wernh. are synonymous with Sherbournia bignoniiflora (Welw.) Hua. The subdivison of S. hapalophylla is reconsidered and two subspecies are proposed: S. hapalophylla subsp. hapalophylla and S. hapalophylla subsp. wernhamiana. According to those changes, S. hapalophylla (Wernham) Hepper var. henrihuana N.Hallé and S. hapalophylla (Wernham) Hepper var. hapalophylla are put into synonymy with S. hapalophylla subsp. hapalophylla.
