Annual herb, up to 400 mm high. Stems erect; viscid glandular-pubescent. Leaves 5-7-foliolate; leaflets linear-spathulate, 5-20 x 1.0-2.5 mm, usually folded along midrib; petioles ± 20 mm long. Flowers: stamens 6-9, filaments slender, pink; sepals pink, 2-3 mm long; petals 5-8 x 1.5-2.5 mm long, mauve-pink to rose; Jul.-Jun. Fruit glandular-pubescent, 25-90 x 2.02.5 mm long; seeds brown, broadly comma-shaped, 1.5-2.0 mm in diameter, transversely rugose.
Leaves 5–7 (9)-foliolate, with glandular-pubescent petioles about 2 cm. long but becoming shorter towards the inflorescences; leaflets 1–3 x 0.15–0.2 cm., linear, often channelled above, subacute or obtuse at the apex, glaucous, sparsely glandular-pubescent or glabrous, very shortly petiolulate.
Inflorescence of terminal, rather lax racemes; bracts similar to the leaves but sessile or subsessile and with progressively fewer leaflets up the stem; pedicels 0.5–1.0 cm. long, slender, glandular-pubescent.
Capsule c. 2–3.5 x 0.2–0.3 cm., on a glandular-pubescent gynophore 2–3 mm. long; valves glandular-pubescent, with about 9 longitudinal, anastomosing nerves; persistent style about 2 mm. long.
Erect annual herb, up to 400 mm tall. Stems viscid-glandular pubescent. Leaves 5-7-foliolate, petioles short. Petals without yellow, transverse bands, 5-8 mm long. Flowers mauve-pink to rose.
Ovary linear, minutely glandular-pubescent, on a glandular-pubescent gynophore c. 1 mm. long; style c. 1 mm. long, glabrous; stigma subcapitate.
Petals 5–8 x 2–.5 mm., from violet to rose-pink, oblong-lanceolate, blunt at the apex, with a basal claw up to 1/3 the length of the lamina.
Stamens 6–9; filaments about as long as the petals, slender, glabrous, purplish; anther-thecae c. 1.5 mm. long, linear.
Annual herb c. 0.3 m. tall, much branched as a rule, with densely glandular-pubescent stems.
Sepals 3–4 mm. long, linear-subulate with hyaline margins, sparsely glandular-puberulous.
Seeds c. 2 mm. in diam., dark brown, transversely rugose.
