Notes
Although the Peters type from Mozambique has been destroyed at B, P. dodonaeifolia Steetz is most likely a synonym as well. The description in F.T.A. (Oliver and Hiern saw the type) is almost identical to that of P. punctulata; the key uses leaf characters only, distinguishing dodonaeifolia by its oval-oblong (not lanceolate) leaves with obtuse, mucronate apex (not acuminate or cuspidate). Faulkner 3211 from coral rag bush on Zanzibar and several other collections from the same area show this type of leaf, but Luke & Robertson 2675 from coral rag in Shimoni, Kenya, has both this type of leaf and normal punctulata leaf on the same branch!Greenway states (on a label) that punctulata occurs on Pemba as well, and therefore I have included P in the distribution list.
