Eremogone ursina is a petite perennial herb forming small tufts no more than 18 centimeters tall. Its small, waxy leaves are needlelike and up to a centimeter long. The inflorescence is an open cyme of white flowers with five petals each under half a centimeter long and protruding purple-anthered stamens. The fruit is a toothed capsule containing 1 or 2 minute purple seeds.
Threats

The biggest threat to the survival of this species is off-roading.[3] Other threats include destruction of its habitat for development, mining activity, and disturbance of the landscape during fire suppression efforts.
