Desert Senna flower, Water Ranch Riparian Preserve, Gilbert, Arizona.

Senna covesii (Desert Senna, Coues' Senna[1], Rattleweed, "rattlebox", "dais" or "Cove Senna") is a perennial subshrub in the family Fabaceae, native to the Mojave Desert and Sonoran Desert in southeastern California, southern Nevada, and Arizona in the United States, and northern Baja California in Mexico. It is found on desert plains and in sandy washes between 500-600 m altitude, and very common in Joshua Tree National Park. The specific epithet honors ornithologist Elliott Coues.

It grows to 30-60 cm tall, and is leafless most of the year. The leaves are pinnate, 3-7 cm long, with 2-3 pairs of leaflets (no terminal leaflet), the leaflets elliptical, 1-2.5 cm long. The flowers are yellow in color, with five rounded petals about 12 mm long.

This shrub is often planted by landscapers and as part of roadside wildflower programs, and is visited by caterpillars, carpenter bees, and bumblebees.
