ANNUAL: Ephemeral herb of the Sonoran Desert spring. Generally small, rarely surpassing 30 cm tall. Usually erect.

LEAVES: Palmate leaves dense with silky hairs.

RANGE: Occurs on sandy to gravel soils in the Sonoran Desert in Arizona. Ranges east to Texas and west to California.

FRUIT: Bean capsules split open explosively as each valve twists in opposite directions - about four bean-seeds are thus ejected a meter or more away from the parent plant.

UNARMED. Without thorns.
