Abstract: Stilbanthus Hook. f is a rare monotypic genus of the family Amaranthaceae. The taxonomic description and the drawing of this genus and species was first reported in Yunnan in this paper according to the specimens from Wuliang Mountain and Luxi County of Yunnan. Till now, the existence of this genus in Yunnan has not been known for certain. Furthermore, this pa- per indicated that there was a mistake in the description and the drawing of the staminodes of this species in Hook. Ic. Pl., 67, pl,1286 in 1879. In fact, the staminodes of this species are not "penicillatis" but lacerate. And the distribution pattern of this genus was discussed.

Key words: Stilbanthus
