Taxonomic Comments
This record represents Senegalia (Acacia) gregii in the narrow sense of FNA (vol. 11, 2023). FNA (vol. 11, 2023) elevates Acacia greggii var. greggii to full species as Senegalia greggii and Acacia greggii var. wrightii to full species as Senegalia wrightii. In contrast, Kartesz (1994), recognized Acacia (Senegalia) gregii in a broad sense with two varieties distinguished: Acacia greggii var. greggii and Acacia greggii var. wrightii.

Known from the southwestern U.S. and adjacent Mexico (Isely 1998; Kartesz 1999). Reported from 33 counties in the southwestern U.S. (Kartesz 2003 draft). Occurs on desert slopes, road cuts, rocky, sandy clay soil with mesquite and cactus, rocky limestone slopes, bottom flood plains with mesquite and grass, roadsides, and washes (Isely 1998). It is occasional to co-dominant (Isely 1998). In California, it is uncommon and occurs in flats and washes in the Mojave and Sonoran Desert (Hickman 1993). It is sometimes cultivated (Isely 1998).
