Revision of the African genus Rhabdophyllum Tiegh. (Ochnaceae) with notes on its distribution within Cameroon and Gabon.

A revision of the African genus Rhabdophyllum Tiegh. is presented, including a key to the species and their distribution within Cameroon and Gabon. The position of the genus within the family Ochnaceae as well as its distinction with other genera of the subtribe Ouratinae is discussed. The view that the subtribe holds four genera, Ouratea Aubl., Campylospermum Tiegh., Idertia Farron and Rhabdophyllum Tiegh. is supported. A new species, R. crassipedicellatum Sosef, is described. The formerly accepted species R. refractum (De Wild. & T.Durand) Tiegh. is seen as being conspecific with R. affine (Hook.f.) Tiegh. Lectotypes are designated wherever necessary and one neotype is proposed.
