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 simulans occurs along the Coastal Plain from Cape Hatteras, North Carolina, southward and throughout Florida. It is self-compatible and autogamous (P. H. Raven and D. P. Gregory 1972[1973]). The species occasionally persists through mild winters in the southern part of its range, appearing biennial. Gaura fruticosa Jacquin 1786, not G. fruticosa Loefling 1758, is an illegitimate later homonym that pertains here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
