Shrubs, scandent, to 3 m. Stems dark brown, pithy, ridged, appressed puberulent when young, glabrescent when mature, with dense brown lenticels. Leaves 3-foliolate; stipels acicular; leaflet blades obovate to broadly elliptic, 5-9 × 3-6 cm, both surfaces appressed puberulent but abaxially especially dense on veins, adaxially sometimes glabrescent, base broadly cuneate to rounded and asymmetric on lateral ones, apex obtuse and cuspi­date. Pseudoracemes usually congested near apex of branchlets, 15-25 cm; flowering branchlet nodes with 3-5 fascicled flow­ers. Pedicels, calyces, and bracteoles yellow sericeous. Corolla red, 0.9-1.1 cm, glabrous. Legume linear, 6-9 × ca. 1.2 cm, flat, papery, brown tomentose, base rounded, apex acute and shortly beaked; abaxial suture narrowly winged, continuous within. Seeds 3-5(-7) per legume, reniform, lenticular. Fl. Jun-Sep, fr. Sep-Oct.

Sparse woodlands in moist soil, along trails; 600-2000 m. NW Guangxi, SW Guizhou, S Sichuan, Yunnan [Laos, Myanmar, Thailand].

The record of Millettia unijuga as treated in FRPS (40: 160. 1994) is based on a single specimen (P. I. Mao 6915, 24 Oct 1955, KUN) from S Yunnan, which was used for the illustration in FRPS (t. 47, f. 1-2). This specimen may possibly represent an as yet undescribed species.
