Description

Highly variable, tap-rooted annual. Glandular, at least on upper part of plant. From simple to branched.

Leaves linear to lanceolate, or the lower obovate. Lower leaves opposite, upper leaves alternate.

Flowers usually terminal and paired, usually one subsessile, the other evidently with a pedicel.

Corolla tube whitish to yellowish, lobes 1-3 mm., pink to lavender, more or less notched.

Fruit is a dehiscent capsule, with one seed per locule. Seeds become mucilaginous when moistened.[1][2]

Bloom Period

March-June[3]

Distribution

Widespread in north America, and on both sides of Cascades, and in temperate south America[1]

Habitat

Lowlands and mountain foothills in open places, dry to moderately moist.[1]

Uses

A good browsing forb for Sage-Grouse chicks.[4]

Seed

Seed Sample from: 2011

Average Measurement: 2.7 x 1.5 x 0.9

Measurement Range: L: 2.3 – 3, W: 1.2 – 1.75, D: 0.6 – 1

Features

Shape: Seeds tapered at hilum and opposite apex. One seed face is mostly flat, while opposite seed face is more rounded.

Color: Seed is tan

Surface: Hilum visible through slightly transparent seed coat as small protrusion. One face of seed has longitudinal sulcus running from hilum to opposite apex. Some seeds covered in flakey coating. Seeds slightly wrinkled, bumpy, and matte. When wet, seed coat forms stringy, mucilaginous substance.
