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. [1][2]
Bloom Period
April to July[1]
Distribution
BC to California, along both sides of Cascades, east to Alberta, Montana, Utah, and New Mexico.[2]
Habitat
Openings, rocky slopes, forest, and shores, coastal to montane.[2]
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.
