Spikes usually nodding, 5-13 cm, sessile. Flowers yellow, ca. 6 mm, subsessile; bract triangular, ca. 2 mm; bracteoles broadly ovate, apex acute. Sepals broadly ovate, ca. 3 mm, apex obtuse. Petals obovate, ca. 5 × 3.5 mm. Ovary ovoid-oblong, hairy; style ca. 1.5 mm. Fruit subglobose, 7-8 cm in diam., ± glabrous. Fl. Mar-Apr, fr. May-Aug.

Some plants from NW, SW, and S Yunnan, which had been pre viously referred to Stachyurus brachystachyus , S. himalaicus var. dasyrachis, and S. himalaicus var. microphyllus, respectively, actually belong to S. yunnanensis. As the type gatherings of these names belong to S. himalaicus, they are reduced here to synonymy under that species.

Broad-leaved forests, thickets; 400-3000 m. Xizang, Yunnan [Bhutan, N India, N Myanmar, Nepal].
