Henderson'S Horkelia (Horkelia hendersonii)
Description
Horkelia hendersonii is a rare species of flowering plant in the rose family known by the common name Henderson's horkelia. It is known from four populations in southern Oregon, including Mount Ashland, and one population south of the border in Siskiyou County, California. It is a resident of dry forest habitat in the granite soils of the Klamath Mountains. This is 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.
