Potentilla tilingii

Potentilla tilingii, commonly known as threetooth horkelia, is a species of flowering plant in the rose family. It is native to all of the mountain ranges of northern California and southern Oregon, where it grows in coniferous forest.

Description
Potentilla tilingii is a perennial herb forming tufts of erect leaves and stems. The leaves are 3 to 12 centimeters long, each made up of hairy gray-green leaflets which are tipped with usually three teeth. Unlike many other horkelias, this species is generally not strongly scented. The green or reddish stems reach a maximum length of about 40 centimeters and hold clusters of flowers. Each flower has minute bractlets beneath small, hairy, pointed sepals and narrow white petals.
