Annual herb, branched, rather weak but erect, up to 5 dm.. Stem with few or more rarely many eglandular hairs or stalked glands on the upper part.. Leaves petiolate, 3-foliolate; leaflets elliptic, obovate-elliptic or practically rhombic, 1–6 cm. long, 0.4–1.8 cm. wide, glabrous or sparsely setulose-pubescent; petiole up to 7 cm. long.. Inflorescence lax and not clearly demarcated, very short or up to 20 cm. long; bracts usually similar in size to the leaves.. Sepals linear to linear-lanceolate, (2–)3–4.5 mm. long, glandular-puberulent.. Petals pink or magenta, ± 1 cm. long.. Stamens 6.. Gynophore 5–8(–13) mm. long.. Capsules 3–6 cm. long, glabrous or subglabrous.. Seeds ±1.8 mm. in diameter, orange to brown, with fine longitudinal striations and low irregular transverse ridges.. Fig. 2/18.
Spreading, widely branching, annual herb to 1 m high, sparsely covered in small, coarse bristles, not strongly foetid. Leaves 3-foliate; leaflets to 3 cm long and 2 cm wide, with coarse bristles especially on margins. Sepals with short bristles. Petals 9–12 mm long, violet-blue turning pink, the 2 central petals with a yellow band; claw short, 2–3 mm long; all 4 petals strongly swept upwards. Stamens 6, free. Ovary on a short gynophore, which lengthens greatly after anthesis, forming a 4–8 mm long stalk separating capsule from corolla scar. Capsule glabrous; valves deciduous. Seeds ribbed, with a white elaiosome.
An annual herb. It grows 50 cm tall. It branches from the base. The stems have fine hairs. The leaves are alternate and have 3 leaflets. The leaf stalks is 7 cm long. The leaflets are 1-6 cm long by 1-2.5 cm wide.
