Potentilla hendersonii, commonly known as Henderson's horkelia, is a rare species of flowering plant in the rose family.[1] It is known from four populations in southern Oregon, including Mount Ashland, and one population south of the border in Siskiyou County, California.[2] It is a resident of dry forest habitat in the granite soils of the Klamath Mountains.
Description
[edit]Potentilla hendersonii grows as a perennial herb producing a low mat of hairy, glandular gray-green foliage about a woody base. The leaves are cylindrical and sometimes tapering to a point, growing erect in a patch around the caudex. Each leaf is 3 to 8 centimeters long and is made up of densely spaced pairs of minutely toothed leaflets. The leaflets are coated in silky hairs. The inflorescence is a dense array flowers atop an erect stalk, each flower made up of five hairy, pointed sepals and five smaller, more delicate white petals.
Threats
[edit]Although few populations of the plant are known to exist, they are not in imminent danger of destruction and a federal listing as an endangered or threatened species was declined in 2003.[2] The Mount Ashland populations of this plant are sometimes threatened by recreational activities at that site, including skiing and maintenance of ski facilities, and off-road vehicle use.[2]
