Subspecies stricta has been collected in several counties near the coast in California (Monterey, Santa Barbara, and Santa Cruz counties) a few times, but the most recent collections are from 1953 and 1995, and it may no longer be naturalized in California. It is naturalized widely in temperate, semiarid areas. (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.
