For the Lomatium genus, mature fruit shape, aspect ratio, and pedicel length are diagnostic.
Native perennial taprooted herb, up to 6 dm tall.
Flowers arranged in compact compound umbels, corolla yellow, pedicels 2-5 m. Involucre lacking, at base of compound umbel, but involucel, at base of each umbellet, present, slightly to strongly toothed.
West Cascades, southern BC southward to southern California.
Low elevations, in open, rocky meadows and slopes, often growing with grasses.
Atseguwi use of leaves as food.
Kawaiisu use of leaves and flowers, fried in fat, as food, and a decoction as a wash for broken limbs.
Salish use of roots, chewed or soaked in water, for headache or stomach issues.
Seeds are most easily sown as soon as they are ripe in a cold frame as stored, as seed can be rather slow to germinate.
When sown in the spring it usually takes at least 12 months to germinate, although this time most might be reduced by cold stratification.
Fresh seed can be sown immediately in site. Division may be possible in spring or autumn.
Seed sample from: 2011

Measurement Range: L: 5.25 – 6.5, W: 2.5 – 4, D: 0.25 – 0.6
Shape: Seeds schizoid, very flat and winged. Hilum and opposite apex are narrower than middle of seed.
Color: Inner seed face is dark reddish brown, with off-white wings. Hilum is tan.
