Annual herb c. 0.3 m. tall, much branched as a rule, with densely glandular-pubescent stems. 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. Sepals 3–4 mm. long, linear-subulate with hyaline margins, sparsely glandular-puberulous. 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. Ovary linear, minutely glandular-pubescent, on a glandular-pubescent gynophore c. 1 mm. long; style c. 1 mm. long, glabrous; stigma subcapitate. 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. Seeds c. 2 mm. in diam., dark brown, transversely rugose.
This species is related to C. hirta but is consistently smaller in all parts.
