Notes. <i>Uvariopsis korupensis</i> is distinguished by its conical flower buds with basally fused petals, and flowers not completely covering the lower part of the trunk; it closely resembles <i>U. submontana</i> (see that species for differences). In the check list of Mt Cameroon (Cable and Cheek 1998), one collection is identified as <i>Uvariopsis</i> sp. (<i>Tchouto 675</i>) which has now been identified as <i>U. korupensis</i>.
