is nearly circular in outline with sometimes five paler radiations. Five
stamens. Flowering late spring into autumn, depending on rainfall.
LEAVES: Leaves are elyptic to lance-shaped and dark green and
considerably hirsute.
RANGE: In the Sonoran Desert in Arizona this plant occurs along the
upper elevations along the eastern tier and is distributed eastward into the
Chihuahuan Desert. Common near Tucson.
