Description
Annual herb growing from taproot with terminal clusters of salmon to white-colored flowers, up to 1 m tall.[2] Stems simple or with axillary branching,[2] white haired.[3] Leaves alternate, entire, lanceolate, to 8 cm long.[2] Inflorescences capitate.[4] Flowers radially symmetrical, 5-merous; calyx 5-lobed, tubular; corolla tubular-funnelform, 5 lobed; stamens 5, epipetalous;[3] pistil 3-carpellate with trifid stigma, superior ovary becoming a loculicidal capsule.[5]
Bloom Period
May-August[2]
Distribution
Widely distributed across Washington; British Columbia to California, east to Rocky Mountains.[2]
Habitat
Open, moist to rather dry areas, low to moderate elevations.[2]
Uses
Infusion of roots or of leaves and stalks taken by Okanogan-Colville as a laxative; Infusion of roots taken by Okanogan-Colville for high fevers; Use of leaves by Paiute and others as a protective covering for filled berry containers.[6]

Seed
Abbreviation: COGRX
Seed sample from: 2011
Average measurement: 3 x 1.5 x 1.1
Measurement range: L: 2.75 - 3.1 W: 1.2 x 1.7 D: 0.9 x 1.3
Features
Shape: One end of seed is slightly more rounded than other. This is the hilium end. One side of seed has longitudinal sulcus that does not reach the hilium or opposite apex.
Color: Hilium indistinct. Entire seed surface mostly uniform in color. Seed is brown with some white spots that are flakey looking.
Surface:Entire seed is very bumpy, sometimes slightly ridged. When wet, seed coat forms many clear, mucilaginous threads.
Could be confused with: Gilia capitata
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.
