Looking straight down on plant

Low, much-branched annual, can be mat-forming. Foliage sticky with glandular hairs. Leaves opposite, succulent, linear, round in profile, leaf measured at 25 mm long by 2 mm wide. Flowers violet, measured at 5 mm diameter. Sepals > petals. Sepal measured at 3 mm long.

Height is listed in Budd's Flora to 20 cm, we measured plants from only 4 to 7 cm tall. 

Habitat is the margins of saline sloughs

Listed as "a rather rare plant" in Budd's Flora; in contrast to this its listed as "Common/Fairly Common?" in Checklist of the Vascular Plants of Saskatchewan.

Because of it's small size, and the white (saline) soil as a background, I found this to be a difficult plant to photograph.
