Psorothamnus spinosus, known as the Smokethorn, Smoketree, Smoke tree, Indigobush, Smokethorn dalea, and Corona de Cristo, is a perennial legume tree common to the desert washes of the southern part of California, Arizona, and most of Baja California, including islands[1] in the northern Sea of Cortez-(Gulf of California). The Smokethorn is also common to Joshua Tree National Park, where it is called the Smoketree.

The twigs of the Smokethorn are slender and densely covered with fine whitish hairs. The flowers are lateral clusters of purple in June, with small seeded pea pods as its fruit.

Distribution

The range of Psorothamnus spinosus is centered north-south along the Lower Colorado River Valley ranging west into mostly all of the Colorado Desert-(subsection of Sonoran Desert), and east of the Colorado River in southwestern Arizona's Sonoran Desert.[2]

To the west in Baja California it borders the western Sea of Cortez; it occurs on the islands there including Isla Ángel de la Guarda, but not Tiburon Island.[3] To the east in Sonora, the species ranges into the northwest of the great Gran Desierto de Altar, on the northern shore of the Sea of Cortez.

In Arizona, the RangeMap also shows that the ranges center on the river courses of southwest Arizona, specifically, the Bill Williams River in the north, then the Gila River[4] in the south. The range also extends into extreme southern Nevada, mostly adjacent the Colorado River.[5]
