Annual or possibly biennial herb, often reddish; stems initially 0, later several, to c. 18 cm long, ± prostrate, not musk-scented, with dense retrorse stiff hairs. Petioles of basal and lower cauline lvs 2.5-5.5 cm long. Lamina 6-10 × 2.5-3 cm, oblong-ovate or triangular-ovate, cordate at base, pinnatisect; lateral lobes extending to > 3/4 way to hairy midrib, ± ovate, ciliate, otherwise almost glabrous, acutely lobed; terminal lobe usually larger. Upper cauline lvs somewhat smaller, subsessile or with short petiole; lamina with narrow-oblong, sharply acute lobes. Stipules membranous, triangular-ovate, densely ciliate, silvery, often tinged red, obtuse. Umbels 2-3-flowered; bracts similar to stipules but smaller. Peduncles and pedicels glandular-hairy, somewhat reddish, = to > calyx at anthesis. Sepals 5-7.5 cm long, ovate or elliptic-ovate, with simple and glandular hairs or glabrate; apical mucro dark. Petals 9-10 mm long; pinkish mauve with dark crimson vein in lower part; claw very short; limb obovate. Stamens 3.5-4.5 mm long, much widened in lower 1/2; anthers dark purple. Staminodes narrower and much < stamens. Fr. beak (7)-7.5-8.5-(9) cm long, with antrorse hairs.
