History
The genus ''Scaphopetalum'' was first described by Masters (1867), based on material from Equatorial Guinee (Mt.John) collected by Gustav Mann. Three species were described by Maxwell T. Masters, '' S. longe-penduculatum'', '' S. blackii'' and '' S. mannii''. Later, É. De Wildeman and T. Durant (June, 1897) described '' S. thonneri'' based on material collected by F. Thonner from northern DRC. A few months later K. Schumann (October, 1897) described four new species, '' S. stipulosum'', '' S. macranthum'', '' S. zenkeri'' and '' S. monophysca''. The last species, ''S. monophysca'' closely resembles ''S. thonerii'' and its description is based on material from Cameroon and Gabon. The next six new species are a contribution of German taxonomists mainly based on material from Cameroon collected by Ledermann, Mildbraed and Zenker. In 1908 H.Winkler describes '' S. paxii''. collected by himself in Cameroon. Engler and Krause described two species in 1911, '' S. pallidinervis'' and '' S. riparia'' and three in 1913, '' S. discolor'', '' S. acuminatum'' and '' S. bruneo-purpureum''. '' S. discolor'' is a species from Congo and the other four from Cameroon. That same year Baker f. described two species based on material collected by Talbot from Nigeria, '' S. parvifolium'' and '' S. talbotii''. The first species for West Africa was described by A. Chevalier in 1917 and named '' S. amoenum''. For the Mayombe region (Gabon) two species were described by Pellegrine in 1921, '' S. letestui'' and '' S. ngounyense''. The first species was made synonym by Halle in 1961 as a variety within S. blackii, '' S. blackii var. letestui''. In the same publication N. Halle splits off another variety '' S. thonneri var. klainei''. Both varieties were described without a prologue in Latin and subsequently invalid. In the same year R. Germain describes a new species '' S. vanderijstii'' and a new variety '' S. dewevrei var. suborophila'' both for DRC. The most recent species is described from Equatorial Guinea, '' S. obiangianum'' by M.E. LealLeal, M.E. (2007) A new endemic Scaphopetalum (Malvaceae) from Mount Mitra, Equatorial Guinea, ''Blumea'' 52 : 137-138. in 2007.Species
