Description
Perennial growing from sometimes clustered and ovoid bulbs. Stem somewhat cylindrical, 15-50 cm tall. 2-4 slender leaves growing from the scape that wither early. Almost spherical multi-flowered white or pink umbels. Tepals 6; pedicals slender 1-2 times length of tepals. Stamens 6 and as long as the tepals. Tepals become papery and converge over fruit with maturity, the fruit 3-celled and 6-seeded.[1] [2]
Bloom Period
May-July [1]
Distribution
California, Oregon, Washington, and British Columbia.
Habitat
Open or wooded areas with clay soils [2]
Uses
The bulbs were occasionally eaten by some northwest coast indigenous peoples.

Seed
Seed sample from: 2011
Average Measurement: 2.1 x 1.7 x 1.7
Measurement Range: L: 1.8 - 2.5, W: 1.5 - 1.8, D: 1.3 - 1.75
Features
Shape: Seeds narrow at hilum end, broadening at opposite apex.
Color: Seeds black. Hilum beige to white.
Surface: Seed’s most distinct feature is extreme puckering or wrinkling. Some seeds have concave pitting, ridging, or some net veined patterns. Seeds roughly textured and matte.
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: elliptical 
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
