Leaves in basal rosette and cauline, basal 3-lobed, cauline (1-2), 3-lobed, reduced, more finely dissected than basal; stipules small, not decurrent on petiole, (margins raggedly fimbriate); petiole 4-8 cm; blade dark green or reddish green, orbiculate, (base rounded), surfaces moderately hairy. Inflorescences 1-3, (lax), erect, 2-11-flowered racemes, sometimes branched, (10-25 cm). Pedicels shorter than hypanthium, (flowers ± sessile). Flowers persistent, fragrant, pendulous; hypanthium broadly campanulate, elongating slightly in fruit, throat not constricted, (length 2 times diam.); sepals erect in bud, widely spreading after anthesis, triangular; petals (partly included), spreading, white, ovate-elliptic, lamina tonguelike, narrowly clawed, palmately lobed, 3-7 mm, ultimate margins lacerate; ovary superior; styles well exserted in fruit; stigma papillae apical. Seeds 0.6 mm, tuberculate (tubercles in 3-19 distinct rows, blunt). Flowering Apr-Jul. Well-drained, moist, semishaded slopes with northern exposure, oak-coniferous woodlands; 100-2200 m; Calif., Oreg.
