Notes
Bamps does not recognise subsp. congoensis (Tiegh.) Robson nor subsp. mechowiana (O. Hoffm.) Robson but sinks them without comment. There does seem to be a difference between theT 7 material and the rest and I have retained subsp. mechowiana. Since Robson records both subsp. afzelii and subsp. mechowiana from Mbala varietal rank might be more appropriate.
