1 Known only from the type, now destroyed. Keyed out by Markgraf with crux-melitensis, both having clavate flowers. He mentions in the key that the perianth (not the androecium) is largely hollow, and in a note that the species is peculiar amongst the New Guinea Horsfieldias because of its large male flowers, which in other species are smaller and almost always broader than long, and that it is without close relatives. 2 The species is possibly related to or may be identical with H. ampliformis.
