Duration: Perennial. Nativity: Native. Lifeform: Forb/Herb. General: Perennial herb 10-45 cm tall, from a long taproot with a subterranean crown or caudex; herbage often gray due to a covering of minute, fine short hairs. Leaves: Usually in a basal cluster, the blades 4-10 cm long, 2 or 3 times pinnately dissected with ca. 4 opposite pairs of lateral primary leaflets; leaflets crowded, the ultimate segments oblong, generally less than 3 mm long, ending abruptly in a small point. Flowers: White, in compact umbels at early anthesis, becoming more open; peduncles exceed leaves with an involucel of conspicuous, linear and distinct, or obovate and connate, scarious-margined bractlets, about equaling the flowers; rays 8-22, spreading, 1-2.5 cm long, unequal in length; pedicels 3-10 mm long; each cluster of umbels about 20 flowered, corolla white to cream. Fruits: Capsule splitting into 2 single seeded mericarps, ovate to oblong-obovate, 6-8 mm long, 4-6 mm broad, the marginal ribs winged, wings narrower than body. Ecology: Found on rocky slopes and mesas from 3,000-7,000 ft (914-2134 m); flowers March-May. Distribution: s CA, s NV, s UT, AZ, w NM, south to Sonora, MEX. Notes: This taxon is distinguished by its low, stemless (except for the flowering stalks) growth form, grayish pubescent herbage, 2 or 3 times dissected leaves and white flowers. Ethnobotany: The roots were eaten raw like radishes, or cooked in the sand and eaten, and the roots used for viral respiratory infections. Etymology: Lomatium is from the Greek loma for bordered, from the prominent marginal fruit wings; nevadense means of or from Nevada.
