Characteristics

Robust creeper or climber 2–8 m. long, the main stems attaining 8 mm. in diameter.. Stems covered with dense short ferruginous hairs, later glabrescent.. Leaflets 3, often pale beneath, the terminal one elliptic, circular, ovate or rhomboid, 4·8–18(–20) cm. long, 3·8–14(–17·5) cm. wide, the laterals obliquely ovate, 4–13 cm. long, 2·5–9 cm. wide, all acuminate, rounded to slightly subcordate at the base, sparsely pubescent to glabrescent above, pubescent to thickly grey, more rarely rusty, velvety beneath with the veins accentuated with ferruginous hairs; petiole 7–10(–14) cm. long; rhachis 2–4cm. long; petiolules 3–6mm. long; stipules elliptic-lanceolate, 1·2–1·4cm. long.. Inflorescences sometimes branched; rhachis 7–35 cm. long; peduncles 2–9 cm. long, ferruginous pubescent to velvety hairy; pedicels 0·7–1·8 cm. long; bracts broadly elliptic or rarely lanceolate, (1–) 1·2–1·8 cm. long, (0·6–) 1–1·6 cm. wide, acuminate, velvety ferruginous pubescent.. Calyx adpressed greyish pubescent with some ferruginous hairs at the base or entirely rusty-hairy; tube 5–6 mm. long; lobes usually unequal, oblong-elliptic, the lowest 1·4–2·3 cm. long, the laterals 0·9–1·7 cm. long, the upper pair joined almost to the apex to form a prominently bifid lip.. Corolla persistent, mostly shorter than the calyx, greenish-cream to orange or pink with red or purple veining and flush, later brick-red; standard almost circular save for claw, 1·8–2·2 cm. long, 1·25–1·8 cm. wide, slightly emarginate, glabrous.. Pods twisted, narrowly oblong, 1·5–3 cm. long, 3·5–7 mm. wide, velvety pubescent.. Seeds blue when fresh, later black, remaining attached to the pod, depressed-globular, longest dimension 5–6·5 mm., shorter dimensions 3·5–4·5 mm.. Fig. 109/1, p. 716.

A robust creeper. It grows 5 m high. The main stems can be 8 mm across. The stems have dense rusty hairs. The leaves have 3 leaflets. These are often pale underneath. The end leaflet is 5-18 cm long by 4-14 cm wide. The side leaflets are 4-13 cm long by 3-9 cm wide. They taper to the tips. The flowering stalks can be branched and they have velvety rusty hairs. The flowers are yellow. The fruit are twisted pods 2-3 cm long by 4-7 mm wide. They are narrowly oblong. They have velvety hairs. The seeds are blue.
