P. nickrentianum is a dioecious plant, with pinnately veined leaf-blades (14 cm by 4.5 cm) on a petiole which is about 1 cm long. The male inflorescence (on a 2 cm peduncle) is up to 4.5 cm long with up to 9 fertile internodes. No pistillate plants were seen by Kuijt. It is very like
Phoradendron undulatum, but differs significantly in being dioecious. ==Taxonomy==
