Discussion | Oenothera podocarpa occurs in Arizona from eastern Mohave County south through the mountains of central Arizona to eastern Pima County and the southwestern quarter of New Mexico, and in Mexico southward in the Sierra Madre Occidental to eastern Sonora and throughout the western halves of Chihuahua and Durango. P. H. Raven and D. P. Gregory (1972[1973]) determined O. podocarpa to be self-compatible and primarily autogamous. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
