Description

Carex filifolia produces clumps of stems which are rounded or triangular, wiry, and angled or curved, reaching up to about 35 centimeters long. The root network is extensive, forming sod. [2] The leaves are narrow and rolled tightly, appearing quill-like.

The inflorescence is up to 3 centimeters long and has flowers coated with reddish scales. The fruit is covered in a sac called a perigynium which is somewhat hairy. The plant produces some seeds, but mainly reproduces vegetatively.

Distribution and habitat

This sedge is native to much of western North America, from Alaska to California and Manitoba to New Mexico, where it grows in moist and dry habitat.

Carex comosa is a species of sedge known as longhair sedge and bristly sedge. It is native to North America, where it grows in western and eastern regions of Canada and the United States, and parts of Mexico. It grows in wet places, including meadows and many types of wetlands. Tolerates deeper water than most common species and is good for retention basins. This sedge produces clumps of triangular stems up to 100 or 120 centimeters tall from short rhizomes. The inflorescence is up to 35 centimeters long and has a long bract which is longer than the spikes. It is a cluster of several cylindrical spikes. The scales over the fruits taper into long, thin awns.

<i>Carex concinnoides</i> Species of sedge

Carex concinnoides is a species of sedge known by the common name northwestern sedge. It is native to western North America from British Columbia to California, where it can be found in moist or dry habitat, often in woodland and forested slopes, on silty and clay soils. This sedge produces loose clumps of stems up to about 35 centimeters in maximum height from long rhizomes. The leaves are thick but narrow, sickle-shaped, and pale green in color. Inflorescences occur at the stem tips, and some pistillate inflorescences grow from nodes along the stem. The spikelets have purplish bracts. The pistillate flowers have four stigmas on each pistil, an identifying characteristic. The fruit is coated in a sac called a perigynium, which is white to light brown in color, purple-tipped, and covered in hairs.
