Oenothera curtiflora is self-compatible and autogamous (P. H. Raven and D. P. Gregory 1972[1973]). Sometimes it is apparently a biennial. The species is native to grassland regions and open areas across much of interior North America. The full extent of its indigenous range is not clear and collections from the eastern half of the United States (Alabama, Florida, Georgia, Indiana, Massachusetts, and Tennessee) and California may be more recent introductions. Gaura mollis Nuttall ex Torrey 1827 is an isonym of G. mollis E. James 1822, a suppressed name. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
