Characteristics

Annual or biennial, hairy, taprooted herb, with sprawling to suberect branched stems to c. 30 cm long, and characteristic scent. Stem base sometimes short and thick with a rosette of lvs. Petioles to c. 10 cm long, reddish where exposed to strong light, usually hairy along 1 side. Lamina very deeply palmately divided, 1.5-5-(7) × 2-6-(8) cm, ± broad-ovate, with hairs scattered above, nearly glabrous below, often turning red with age; lobes 5, pinnatisect or less commonly pinnatifid; ultimate segments mucronate. Infl. very diffuse; fls paired; peduncles and pedicels variable, with simple and glandular hairs, often with a line of hairs along 1 side. Sepals (at anthesis) 5-8 mm long including apical awn, ovate, with mostly glandular hairs, ± reddish. Petals 6-9 mm long, ± oblanceolate, pink to rose; claw a little > limb; apex rounded. Filaments pinkish; anthers yellow. Mericarps 2.5-3 mm long, with short hairs; upper ⅔ with many, close, transverse ridges. Seed smooth.

More

Annual herb, stems up to 6 long, erect or ascending, pilose with spreading gland-tipped hairs. Stipules ovate, acute. Radical leaves several, petioles up to ±100 mm long, hairy as the stems; blade up to 80 mm in diam., divided to the base into 3-5 lobes, each lobe ovate in outline, base cuneate tapering to a petiole-like part (the leaf looks compound), bipinnatisect, with a few long coarse hairs above and below, or almost glabrous; cauline leaves similar but petioles rapidly shorter. Peduncles opposite the leaves and terminal, forming compound cymes, mostly 2-flowered, pilose with spreading glandular hairs and shorter, curled eglandular ones. Pedicels similar to peduncles. Sepals ±5-6 x 2.5 mm, ovate, glandular-pilose. Petals ±9 x 2.5 mm, elliptic-oblong, entire, narrowed to a claw, purplish-pink. Rostrum glabrous. Carpels transversely ridged, glabrous.
