Description
General: Annual, the stem simple or branched, erect, 0.5-5 dm. tall, minutely pubescent. Leaves: Lower leaves opposite, petiolate, often toothed when well developed; upper leaves opposite or whorled, entire, usually glabrous, becoming sessile upward, narrowly elliptic or oblong to nearly linear. Flowers: Flowers 1-few on short pedicels in the axils of reduced upper leaves; calyx 5-8 mm. long, 5-lobed; corolla bi-labiate, blue with white or pinkish upper lip, 9-17 mm. long, the tube abruptly bent at a right angle to the calyx, shortly pouched at the bend; stamens 4. Fruit: Capsule opening along 4 lines.

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
