Abstract

Rhysotoechia welzeniana (Sapindaceae) is described from the April River in Papua New Guinea, one of the classical localities on the Kaiserin-Augusta-Fluss itinerary of 1912–13. The new species is the first dioecious member of its genus and the only one with foliage consisting entirely of simple leaves.
