- Comments
- First discovered in 2006 in Norfolk; collected at the same location in 2007 growing on Medicago lupulina at a car wash and reported to USDA. Eradication was planned for spring, 2008. Found near a farm field in Virginia Beach in 2012 (R. Bray, pers. comm.) and in a lawn in Newport News in 2023. Additional reports for Virginia Beach have been forthcoming.
According to the online FNA beta treatment of Orobanchaceae, it is likely that the traditional genus Orobanche will be divided into three or more genera once the phylogeny of segregates is clarified by further molecular studies. Several subspecific segregates have also been recognized within Orobanche ramosa, but continuous variation in the diagnostic characters has made their recognition controversial. Until these taxonomic issues get better sorted out, we are maintaining the traditional, broad, species circumscription for Virginia material. - Habitat
- Ruderal habitats. Rare in the Coastal Plain.
