This small perennial plant is native to the White Mountains which straddle the California-Nevada state line and the Inyo Mountains nearby.

It lives on barren rocky scree above 3000 meters.

This alpine-adapted plant forms cushion-like mats amongst the rock litter on mountain peaks.

At flowering small bunches of tiny buds open to reveal bright yellow petals each a few millimeters wide.

The fruits are hairy, slightly inflated siliques less than a centimeter long.
