Notes. – This species is found in Nigeria ( VERDCOURT, 1977). The type collection of Psychotria obanensis has two duplicates, both of them deposited in institutions where Wernham apparently worked. The specimen at BM, where Wernham’s types are assumed to be deposited (Stafleu & Cowan, 1988) has a typewritten or printed label that identifies it as Talbot 244 from “Oban, S. Nigeria, 1911”, and another typewritten label that identifies this as the type of P. obanensis with the place of publication of this name. The specimen at K has a label in Wernham’s handwriting with the locality and collector data and the name P. obanensis . The specimen of Talbot 244 at BM is in much better condition than the one at K. VERDCOURT (1977: 798) formally cited the BM specimen as the holotype and the K specimen as an isotype, and is followed here.
