Staminal tube ca. 4 × 3 mm, outside pulverulent pubescent, inside glabrous, apical margin 8-lobed; anthers 8, alternate with tube lobes, oblong.

This species is perhaps conspecific with Dysoxylum cyrtobotryum Miquel, a widespread species of Malesia to the Solomon Islands.

"Dysoxylum oliganthum" (C. Y. Wu, Fl. Yunnan. 1: 247. 1977) belongs here but was not validly published because two gatherings were indicated as types (Vienna Code, Art. 37.2).
