About
Strombocarpa pubescens (formerly Prosopis pubescens), commonly known as screwbean mesquite, is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States (Texas, Arizona, New Mexico, California, southern Nevada and Utah) and northern Mexico (Baja California, Chihuahua, Coahuila, Sonora).
Where it grows
It is found along streams and valleys in deserts, particularly in damp or saline soil. It grows alongside common plants of this habitat type, such as arrowweed (Pluchea sericea) and tamarisks. It can be found on playas and other areas of alkaline substrates. This and other mesquite species are dominant plants in the Mesquite Bosque-mesquite woodlands, a common habitat type in the desert southwest region.
