Potentilla webberi, commonly known as wire mousetail and Webber's ivesia, is a species of flowering plant in the rose family.[1] It is native to the United States, where it occurs in the northernmost part of the Sierra Nevada and the adjacent Modoc Plateau in California, its range extending just into Nevada.[2]

Description

[edit]

Potentilla webberi is a small perennial herb forming a clump on the ground in the clay soil of the local sage scrub. Each leaf is up to 7 centimeters long and is made up of several hairy, lance-shaped green leaflets each 3 to 10 millimeters long. The red to reddish-green stems are generally not erect and are up to 15 centimeters long on the ground or drooping over it. A stem bears an inflorescence made up of a single cluster of several flowers. Each flower is about a centimeter wide with five triangular to lance-shaped greenish sepals and five bright yellow petals. In the center of the flower are five stamens and usually five pistils.
