About Carex concinnoides Mack.
Carex concinnoides Mack. is a species of sedge with the common name northwestern sedge. It is native to western North America, ranging from British Columbia to California. This plant grows in both moist and dry habitats, most commonly in woodland areas and on forested slopes, growing in silty and clay soils. This sedge grows in loose clumps, producing stems that reach a maximum height of around 35 centimeters from long rhizomes. Its leaves are thick but narrow, sickle-shaped, and pale green. Inflorescences develop at the tips of stems, and some additional pistillate inflorescences grow from nodes along the stem. The plant's spikelets bear purplish bracts. A key identifying feature of this species is that each pistil of its pistillate flowers has four stigmas. Its fruit is enclosed in a hair-covered sac called a perigynium, which ranges from white to light brown in color and has a purple tip.
