A passage from Medicinal Plants of the American Southwest:

From the southern half of Arizona, Acacia constricta is found east to southern New Mexico’s Gila River, continuing to the Rio Grande and Pecos River Drainages, finally to Trans–Pecos Texas. A. constricta is found from 2,000’–6,000’ in many areas where A. greggii is present. Look to drainages, slopes, and hillsides.
