Description:  "Perennial herbs from stout scaly rhizomes usually 1-4 cm long, also producing long stolons. Leaves somewhat coriaceous, leaflets 2.1-5 (-6) cm long, 1.2-3.5 cm wide, upper surface with conspicuously impressed veins, glabrous or with a few scattered long hairs, lower surface densely silky long-strigose, margins coarsely serrate, sometimes only in upper 2/3, lateral petiolules 0.2-1 (-2.5) cm long, petioles (3-) 12-16 (-21) cm long, densely long-strigose, stipules brownish, 1-1.6 cm long.  Flowers 1 to several, scapes usually ca. 1/2 as long as petioles at anthesis, apparently elongating after anthesis to nearly as long as petioles, pedicels usually 20-50 mm long; epicalyx lobes narrowly lanceolate, (3-) 5-6 mm long, densely silky long-strigose; sepals lanceolate, ca. 7-8 mm long, enlarging to 9-10 mm long in fruit, densely silky long-strigose; petals white, broadly obovate, 8-11 mm long.  Fruit red, broadly conical, ca. 1-1.5 cm long, hirsutulous, achenes ca. 1.5 mm long, slightly embedded in shallow pits of the receptacle"  (Wagner et al., 1999; p. 1103).

Habitat/ecology:  In Hawai‘i (native), "occurring in dry, disturbed areas, wet forest, and subalpine shrubland, 1,160-3,070 m"  (Wagner et al., 1999; p. 1103).  "In Chile this species grows in the following environmental conditions:  Medium altitude up to the timber line; 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). Some shadow. some protection against direct sunlight, some shadow from vegetation, filtering about 20-40% of light; in shadow, steep slopes facing south or a vegetation cover which filters 40-80% of light"  (Chileflora).

Propagation:  Rhizomes, stolons, seed (spread by frugivorous birds).

Native range:  "Pacific coast of North America from Alaska to California, disjunct in South America from Chile to Argentina and the Juan Fernández and Hawaiian islands"  (Wagner et al., 1999; p. 1103).
