Morphology General Habit
Subshrub with slender rampant stems 0.5–1 m long, mostly purplish-brown, pubescent bifariously or all round with tubercular-based hairs but scarcely scabrid.
Morphology Leaves
Leaves 2–4-foliolate; leaflets 15–35 × 8–18 mm, obovate-elliptic, obliquely emarginate at the apex, obliquely truncate at the base, glabrous, entire or obscurely ciliate; main nerve distinctly lateral with 3–4 other basal nerves; venation reticulate beneath; petiole 6–13 mm long, rhachis 5–10 mm long, both similarly hairy to the stem; stipules 6–18 × 2.5–9 mm, ovate or elliptic, rounded to acuminate at the apex, unequally biauriculate at the base, entire, glabrous or ciliate, denticulate, persistent, densely veined.
Morphology Reproductive morphology Inflorescences
Inflorescence often on leafless shoots, densely strobilate, 1.5–3 cm long; peduncle 1–15 mm long, pubescent; pedicels 3 mm long; bracts green or yellow, often turning reddish, 7–15 × 8–15 mm, rounded, divided into two lobes for one-quarter to half of their length, or outer ones for their entire length; lobes ovate, obtuse, glabrous, ciliate-denticulate; bracteoles 1.6–2.5 × 0.8–1 mm, lanceolate, sparsely ciliate.
Morphology Reproductive morphology Flowers Calyx
Calyx lobes glabrous, 7–8 × 3 mm, elliptic-oblong, the upper 2-fid, the lower 3-fid.
Morphology Reproductive morphology Flowers Corolla
Standard yellow or orange, 6–10 × 5–8.5 mm, panduriform.
Morphology Reproductive morphology Fruits
Fruit of 1 kettle-drum-shaped article, 5.5 mm long and wide, the upper margin straight, the lower margin very rounded.
Morphology Reproductive morphology Seeds
Seeds chestnut-brown, compressed, 3.2–3.5 mm long and wide, l.5 mm thick, almost round in outline; hilum small, eccentric.
