Morphology Stem
Stems pubescent with tubercular-based hairs or, in some areas, glabrescent.
Morphology Leaves
Leaves sensitive, 10–40-foliolate; leaflets 6–15 × 1–4 mm, linear-oblong, rounded but mucronulate at the apex, obliquely rounded at the base, entire, glabrous; venation obscure; petiole and rhachis together 1–6 cm long, with tubercular-based hairs; petiolules 0.5 mm long; stipules 6–16 × 1–2.5 mm, oblong-lanceolate, straight, spurred, soon falling.
Morphology Reproductive morphology Inflorescences
Inflorescences leaf-opposed, 3–7-flowered; peduncle 1–15 mm long; rhachis 1.5–8 cm long; pedicels 2–5 mm long; bracts 4–5 × 1–1.5 mm, deciduous; bracteoles 2.5–3.5 × 1.5 mm, ovate-elliptic, ciliate.
Morphology Reproductive morphology Flowers Calyx
Calyx glabrous or ciliate, 2-lipped; lips 3.5–4 × 2.5–3 mm, broadly oblong, one emarginate, the other 3-toothed at the apex.
