Liana large, climbing. Stems cylindric, dark brown, densely scattered with white to brown lenticels, pithy inside; young shoots yellow tomentose, glabrescent when mature. Stipules ovate-triangular, ca. 3.5 × 3.0 mm. Leaves imparipinnate, 13–17-foliolate (usually 13), juvenile at anthesis, reddish when young; rachis 21.8–38.8 cm long, including petiole 8.6– 14.0 cm long; leaflet blades oblanceolate to oblong, 5.8–20.3 × 2.3–6.1 cm (ratio usually 2–4), papery to subleathery, glabrous above, appressed pubescent to densely hairy beneath, acute to acuminate at apex, cuneate to rounded at base; lateral veins 10–16 on each side of midvein, obvious, looped near margin; petiolules ca. 5 mm long; stipels absent. Pseudoracemes 10.9–39.8 cm long, usually inserted in the leafless axil of leaf on the lower part of branchlets of current year; rachis appressed hairy; brachyblasts distinct, wart-like or knob-like, up to 7–11 mm long on the lower part, with 3–5 flowers on the top of each brachyblast; bracts inserted at base of brachyblasts and pedicels; bracteoles 2, inserted at the base of calyx. Flowers pink, pale purplish white to white, ca. 2.1–2.6 cm long; pedicels 0.7–1.2 cm long, appressed tawny hairy; calyx campanulate, dark red, 5-lobed, pubescent outside, with short calyx lobes, the lower lobe longest, ca. 2 mm long, 4 mm wide, the tube ca. 6 mm long; standard blade glabrous, suborbicular, ca. 2.3 × 2.1 cm, reflexed, emarginate at the apex, with a yellow-green patch and a 3.5–4.5 mm long claw; wing blade pubescent on the outer surface at apex, oblong, ca. 1.8 × 0.7 cm, with a 7 mm long claw; keel blade pocketed at side, pubescent on the outer surface at apex, oblong, 1.6 × 0.7 cm, with a 7 mm long claw; stamen 10, monadelphous, 2.2 cm long, with two small openings (fenestrae) at base; floral disk indistinct; ovary appressed hairy, 2.2 cm long, with 6–8 ovules; style inflexed, glabrous; stigma minutely capitate.

Seeds 1–5, large, dark brown, reniform, 2.1–3.3 × 1.8–2.4 cm.

Phenology and habitat: —Flowering from March to June, and fruiting from April to next March. The flowers and leaves develop together. It grows in evergreen forests at elevations of 0–2500 m.

Distribution: — Bhutan, China, India, Laos, Myanmar, Nepal, Thailand and Vietnam ( Fig. 5 ).

Notes: —Transfer of Millettia pachycarpa Bentham (1852) to Derris Lour. would lead to a later homonym because of the existence of Derris pachycarpa Merrill (1922: 312) . Pongamia taiwaniana Hayata (1913) is the next earliest legitimate name for this species. Therefore, according to Art. 11.4 of the ICN ( Turland et al. 2018), we made the new combination Derris taiwaniana (Hayata) Z.Q. Song based on Pongamia taiwaniana Hayata. This new combination is not threatened by the nomen nudum “ Derris taiwaniana Matsum. ”, which is merely cited as a synonym of Pongamia taiwaniana , and thus, an invalid name (Art. 36.1, Turland et al. 2018).
