Description

[edit]

Potentilla muirii is a small perennial herb growing in tufts of erect leaves and stems. The leaf is 2 to 5 centimeters long and is made up of many densely hairy overlapping leaflets such that the leaf is a cylindrical, pointed, whitish to silvery body. The mostly naked stem is up to 15 centimeters long and holds an inflorescence of clustered flowers. Each flower is about half a centimeter wide, with triangular sepals covered in long, white hairs. Between the sepals are narrow, pointed petals of bright yellow. In the center of the flower are a few stamens and pistils. The fruit is an achene about two millimeters long which is gray with reddish spots.
