The three species occur only in the northeastern part of the Mojave Desert of North America, and are all uncommon.

The plants consist of one or a cluster of basal rosettes of leaves with a generally light blue or grey appearance.

Closer examination shows the leaves to be generally wedge-shaped, with the end of each divided into several teeth, and entirely covered with long hairs 5–15 mm in length.

The solitary terminal flowers are typical of poppies, with 2-3 sepals and 4-6 petals, either white or yellow, and starting out as nodding bud before become erect.

The fruit capsule has 4-6 valves, opens from the top as it dries, releasing a handful of small wrinkled black seeds.
