Description:  "Annual, at first stemless, later usually with several stems, extremely variable in size according to habitat, from prostrate to c. 60 cm high and c. 1 m across, densely glandular and ± musk-scented. Leaves to c. 30 cm long, pinnate, with petiole sometimes = leaf rachis. Leaflets sessile, pinnately lobed; lobes ± ovate, serrate. Stipules broad-ovate or suborbicular, membranous, silvery, obtuse. Umbels c. 12-flowered; bracts broad, membranous, obtuse; peduncles and pedicels densely glandular, < to slightly > calyx at anthesis. Sepals 4.5-6 mm long, lanceolate-oblong, densely glandular, mucronate. Petals 4.5-8 mm long, pink or mauve-pink; claw very short; limb ± elliptic-oblong, sometimes almost obovate. Stamens 3-4 mm long; filaments widened at base, white or pink, usually with a small membranous tooth on 1 or both sides, rarely without teeth; anthers dark purple. Staminodes lanceolate. Fruit beak 3-3.5 cm long, puberulent. Mericarps densely hirsute with hairs of differing length; apical pits prominently glandular, with 1 broad, glabrous furrow beneath"  (Webb et al., 1988; p. 725).

Habitat/ecology:  In New Zealand, "roadsides, railways, waste places, building sites, quarries, riverbeds, lawns and pastures, and cultivated ground; lowlands throughout, common"  (Webb et al., 1988; p. 725).  "In Chile this species grows in the following environmental conditions:  Low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m. Humid areas, with almost constant rainfall, short dry periods are possible (generally not longer than 1 month); somewhat dry areas where the drought may last 3-5 months, precipitations of 400-800 mm. are concentrated in winter. Fully exposed to the sun, level areas or slopes facing north"  (Chileflora).

Propagation:  Seed

Native range:  Canary and Madeira Islands, northern Africa, Europe, western Asia; widely naturalized elsewhere (GRIN).
