The Catclaw Acacia is native to South and Central Texas. It also is present natively in Utah, Nevada, New Mexico and parts of California and southeast Arizona. In Mexico, the plant ranges into the state of Sonora in the northern area of the country. At Brackenridge Field Lab, this shrub appears in the Experimental Garden and old quarry next to it. There is also a plant on the UT main campus, on the south side of the old Botany Greenhouse.

Other common names, some humorous, include: paradise flower, catclaw mesquite, wait-a-minute bush, or wait-a-bit tree. The last three names are because the tree has numerous hooked thorns that look a lot like a cat’s claw. A person walking by might get “hooked” by the plant, and thus have to stop to carefully remove themselves from its grasp.

The scientific name is in honor of botanist, Charles Wright (1811-1885). Born in Connecticut, Wright later moved to Texas to become a land surveyor and teacher. Here he collected plants for Asa Gray, considered one of the most important 19th century American botanists. Wright was one of three botanists associated with the expedition that surveyed the border between the U.S. and Mexico. Prior to this, he accompanied an earlier army expedition that prepared for this much larger survey. Wright would collect not only in Texas, but places all over the world including Cuba, South Africa, the Bering Strait, Australia, and Japan. No small feat considering methods of travel for Wright included long ship journeys and miles of walking.
