Subspecies 2 (1 in the flora). Oenothera stricta is a PTH species and forms a ring of 14 chromosomes in meiosis, and is self-compatible and autogamous (W. Dietrich 1977). Subspecies stricta is naturalized in many areas around the world and may be so in California. Subspecies altissima W. Dietrich occurs only in Argentina.

Oenothera neomexicana is known from central to western New Mexico west of the Rio Grande Valley, except for the Organ Mountains, and eastern and central Arizona from the White Mountains south to Mount Graham and northwestward across the Mogollon Rim in Coconino and Yavapai counties. Oenothera neomexicana had been assumed to be self-incompatible (W. L. Wagner et al. 2007), but K. E. Theiss et al. (2010) determined one population sampled to be consistently self-compatible.
