Description

Native tufted perennial, reaching 1-4 dm in height.

Leaves are grass-like, reddish to green, with long, fine hairs along leaf margin.

Inflorescence consists of 1 to 6 brownish glomerules (a condensed, headlike, cluster of flowers). The individual flowers consist of 6 membranous pallid, brownish tepals. Luzula comosa var. laxa generally has a more open, subumbellate inflorescence than Luzula comosa var. comosa, which has a tighter capitate inflorescence.

Juncaceae family members are differentiated from grasses in that they typically feature round stems, without nodes. [2][3]

Bloom Period

April to July[2]

Distribution

BC to California, along both sides of Cascades, east to Alberta, Montana, Utah, and New Mexico.[3]

Habitat

Openings, rocky slopes, forest, and shores, coastal to montane.[3]

Seed

Seed sample from: 2008

Average Measurement: 1.5 x 0.9 x 0.9

Measurement Range: L: 1.2 – 1.8, W: 0.8 – 1, D:0.8 – 1

Features

Shape: Seeds have prominent white caruncle. Seed mostly round except for a slightly pointed tapering at hilum and opposite apex.

Color: Seed coat is white over a dark reddish brown seed body.

Surface: On one side of seed there is a cloudy white line that crosses from hilum to opposite apex. Seed is lustrous and marked with many fine longitudinal lines.
