Oenothera species 1 [australis] . Phenology: Mar-Sep. Habitat: Dunes, other dry sandy areas near the coast. Distribution: Along the TX coast, south to TAM.
Origin/Endemic status: Native
Taxonomy Comments: Requiring additional study, and perhaps intergrading with C. serrulatus in e. TX. From Towner (1970): “The two species seem to come into contact only in inland eastern Texas. In Brazos and Madison counties, the populations are australis-like, and in neighboring counties to the north the plants combine the pubescence of C. australis and the large leaves of eastern C. serrulatus. These intermediate populations seem to be isolated slightly from the main distributions of the two species. They may be occupying an area of former hybridization or they may be further autogamous derivatives of C. drummondianus [= O. capillifolia].”
