Oenothera fruiticosa L.
Given the provisional nature of Weakley's treatment (2012 Draft Flora of the Southern and Mid-Atlantic States), with "further revisions likely" in this section of the genus, we have elected to stay with Straley's treatment (1977, Ann. Missouri Bot. Gar. 64) of this taxon and O. tetragona as subspecies of O. fruticosa.

Treated as a species, O. fruticosa s.s. has three varieties in Virginia, according to Weakley, with four vars. being recognized under O. tetragona, two of them perhaps more closely related to O. fruticosa (see Comments under O. fruticosa ssp. glauca). Given the frequent difficulties of distinguishing just two taxa in the O. fruticosa / tetragona complex, we will resist further splitting until additional field and herbarium studies can be done.
Mesic to dry forests and woodlands, barrens, outcrops, clearings, peaty swales, ditches, fields, and roadsides. Frequent to common throughout, but apparently absent from far sw. Virginia.
