Pectis cylindrica (Sonoran cinchweed) is an annual plant and species of Pectis. Pectis cylindrica is native to the southwestern United States (Arizona, New Mexico and Texas) and in northwestern Mexico (Baja California Sur, Chihuahua, Coahuila, Durango, Nuevo León, Sinaloa, Sonora). Pectis cylindrica is similar to Pectis prostrata and the two occasionally grow together. Some herbaria contain mixed collections of the two although no evidence is available of hybrids between them.
