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.

摘要： 巨苋藤（Stilbanthus scandens Hook．f.）是亚洲苋科植物中最大的种类，并且是一个十分罕见的单种属，云南文献中至今未见到该属种的可靠分布记载和图文资料。本文依据采自景东县无量山及潞西县勐戛乡的标本，确证该属种在云南的分布，并给予图文报道，而且指出W．J．Hooker在1879年发表本种时将其退化雄蕊描述并画为“画笔状”的图文错误，实际应为“流苏状”。同时根据目前已有的资料对其分布式样进行讨论。
