Erigeron linearis is a species of flowering plant in the family Asteraceae known by the common name desert yellow fleabane or narrow leaved fleabane. It is native to western North America.[2]
Description
[edit]Erigeron linearis is a small clumping perennial herb reaching a maximum height of 20 centimeters (8 inches), with a woody taproot. Its leaves are long and narrow, mostly clustered around the base of the stem, and are 2 to 9 cm (3⁄4 to 3+1⁄2 in) long, pale green to green, and lightly covered with short white hairs. The erect lightly hairy flower stems are leafless or have a few reduced linear leaves and usually produce only one flower head (though occasionally 2 or 3) each about 1 cm (3⁄8 in) wide. The flower has a center of many golden yellow disc florets and a fringe of as many as 38 pale to bright yellow or cream-colored ray florets. The fruit is an achene attached to a fluffy pappus with 10 to 20 bristles.[3] Seeds are presumably wind dispersed.
Distribution and Habitat
[edit]Erigeron linearis is native to the mountains of western North America from British Columbia as far south as Wyoming, northern Nevada and Mono County in California.[2][4] The species grows in open rocky slopes associated with the shrubs sagebrush, bitterbrush or juniper.[5]
Uses
[edit]Some Plateau Indian tribes used desert yellow fleabane as a poultice for treating sores.[6]
