Suffrutescent perennial/subshrub in arroyo gravels and among boulders at base of exposed cliff faces in a 1/2 mile long, narrow, steep walled, dry, slot canyon cut in flat lying pale, blocky, limestone strata by a intermittent arroyo tributary of Fresnal Creek, and sheltering a richly diverse flora of the remote, poorly accessible region known as Hell's Half-acre.
