Robinia neomexicana, the New Mexican, New Mexico, Southwest, desert, pink, or rose locust, is a shrub or small tree in the subfamily Faboideae of the family Fabaceae.

[4] In California, it is uncommon below 1500 m (5000 ft) in canyons in the Mojave Desert and its sky island pinyon-juniper habitats (Pinus monophylla and Juniperus californica).

[5] Farther east, it is typically found between 1200 and 2600 meters (4000 and 8500 feet) along streams, in the bottoms of valleys, and on the sides of canyons.

The leaves are 10–15 cm long, pinnate with 7–15 leaflets; they have a pair of sharp, reddish-brown thorns at the base.

[7] Blooms are produced in spring or early summer in dense racemes 5–10 cm long that hang from the branches near the ends.
