Notes.

Annickia affinis is distinguished by having overall glabrous branches and petioles and the lower side of the leaf blades which is sparsely pubescent with simple or bifid hairs pointing in the same direction. Annickia affinis is morphologically close to A. chlorantha from which it is distinguished by having a glabrous upper midrib surface (versus pilose in A. chlorantha ). In addition, A. chlorantha has few simple hairs pointing in different directions combined with smaller bifid or trifid hairs.

Annickia affinis is the most common species of Annickia and is generally found as a young plant in secondary forest, or as an adult in older secondary or primary forests. For a long time (and still now) Annickia affinis was confused with A. chlorantha (or even Enantia chlorantha ), but the latter name is attributed to a different and rarer species ( Versteegh and Sosef 2007). Thus, most literature refers to the old name A. ( Enantia ) Enantia chlorantha when referring to A. affinis (the common and widespread species). Previous reports of A. chlorantha outside Nigeria and Cameroon (e.g. Gabon) refer to A. affinis .
