Discussion
From molecular evidence, S. C. Meyers and A. Liston (2008) suggested that Plantago ovata was introduced to North America during the Pleistocene. They recognized four varieties; North American specimens can be treated as two varieties based on bract and corolla color: the inland var. fastigiata (E. Morris) S. C. Meyers & Liston (midribs of mature flower bracts green, corolla lobes without reddish brown midribs) and the coastal var. insularis (Eastwood) S. C. Meyers & Liston (midribs of mature flower bracts brown, corolla lobe midribs prominent, reddish brown). Unfortunately, these features are not easily seen on many herbarium specimens, and these taxa are not recognized here.
