Summary

A revision of the genus Talbotiella Baker f. (Caesalpinioideae: Leguminosae) is presented. Four species from Cameroon are described as new and a species of Hymenostegia, also from Cameroon, is transferred to Talbotiella bringing the number of species in Talbotiella to eight: T. bakossiensis Cheek, T. batesii Baker f., T. breteleri (Aubrév.) Mackinder & Wieringa, T. ebo Mackinder & Wieringa, T. eketensis Baker f., T. gentii Hutch. & Greenway, T. korupensis Mackinder & Wieringa and T. velutina Burgt & Wieringa. The centre of diversity is Cameroon where six of the eight species occur, five of which are country endemics. Vegetative characters that can be used to distinguish the species are provided in tabular form. Species distributions are mapped and all species are assessed for conservation status.
