Carex filifolia is a species of sedge known by the common name threadleaf sedge. It is native to western North America and grows on slopes, eroded areas, gravel, and dry habitats.[1]
Description
[edit]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
[edit]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.
