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.

P. H. Raven and D. P. Gregory (1972[1973]) determined Oenothera sinuosa to be self-incompatible. Oenothera sinuosa is endemic to Oklahoma and Texas and is escaped or naturalized in Alabama, Arkansas, California (where found to 1300 m), Florida, Georgia, Missouri, and New York. Oenothera sinuosa is potentially a noxious weed due to the aggressive rhizomatous habit, but is somewhat limited by its self-incompatibility. Molecular data (G. D. Hoggard et al. 2004) are consistent with the hypothesis that the allotetraploid (2n = 28) O. sinuosa arose by interspecific hybridization of two species within subsect. Stipogaura as suggested by P. H. Raven and D. P. Gregory (1972[1973]). The molecular data indicate that the pistillate parent came from O. calcicola or a close relative, while the staminate parent originated from the lineage that gave rise to O. cinerea and O. filipes.
