    Shoots
    Year-old shoots with leaves well spaced, almost erect (up to 40 cm tall) or with prostrate presumably subterraneous lower part up to 10–15 cm long which later becomes a part of the rhizome.
    Stem
    Stems c. 1 mm in diameter, with epidermis cream-coloured to reddish when dry, with ± dense indumentum of spreading curled hairs in the upper and younger part to subglabrous in the lower and older part but then usually with a tuft of hairs in the leaf axils where buds occur.
    Leaves
    Lower leaves (1 to several on erect shoots; up to 11 on ascending ones) small, c. 1.5 mm long, scale-like, with margins in lower part glandular and with apex 3-lobed; the rest of the leaves sessile, 3-foliolate; rhachis up to 1 mm long or almost absent, sparsely hairy, persisting after the leaflets fall; basal leaflets 8–13 × 4.5–21 mm, usually 1.7–2 times longer than wide, asymmetrically ovate-oblong with a basal angle often more than 100º, subacute to obtuse at the apex; apical leaflet 12–22 × 6–12 mm, obovate, symmetrical, rounded or cuneate at the base, acute to obtuse at the apex; all leaflets glabrous on the upper surface, glabrous beneath or with a few hairs only on the midrib and sometimes basally near the margin, subcoriaceous, densely red-dotted above and beneath; stipular glands blackish, minute, usually persistent after leaflets fall.
    Inflorescences
    Umbels 2–5-flowered; peduncle (30)50–100 mm long, with indumentum of spreading curled hairs; foliage leaf on the peduncle usually 1-foliolate, small, with 2 blackish small glands (stipules) at the base; pedicels 1–2.5 mm long, densely spreading hairy; glands (bracts) at the base of the pedicels small, inconspicuous or lacking.
    Calyx
    Calyx reddish, with sparse weak hairs up to 1.3 mm long; hypanthium c. 1 mm long, calyx tube 2–2.5 mm long above the insertion of the stamens; calyx teeth 3–3.5 mm long, triangular-acuminate, the 2 upper ones wider than the others.
    Corolla
    Corolla pink, the standard crimson on the back, and the keel with deep purple tip; standard 12–13 × 7–8 mm, slightly violin-shaped, wedge-shaped at the base, retuse, the margins thickened and infolded over c. 3.5 mm from the base; wings 12–13 mm long including the 2.5–3 mm long claw, the blade 9.5–10 × 5.5–6 mm, oblong, strongly auriculate; keel 10.5–11.5 mm long, slightly curved, pointed, the claws c. 2.5 mm long.
    Filaments
    Filament sheath 6–7 mm long, papillose near the base; free parts of the shorter filaments 2–2.5 mm long, those of the longer filaments 3–4.5 mm long.
