Rupertia hallii

Rupertia hallii is a species of flowering plant in the legume family known by the common name Hall's California tea, or Hall's rupertia. It is endemic to California, where it is known only from a small section of the northern Sierra Nevada foothills on the border between Butte and Tehama Counties. It is a perennial herb approaching a meter in height with slender, leafy branches. The leaves are each made up of three lance-shaped or oval, pointed leaflets measuring up to 9 centimeters long. The inflorescence is a clustered raceme of several whitish or yellowish pealike flowers. Each flower has a tubular calyx of sepals and a corolla spreading to about a centimeter in width. The fruit is a hairy, gland-speckled legume around a centimeter long.
