Discussion
Varieties vernonioides and menziesii appear to be completely intergrading. Glabrous or glabrate plants with entire leaves are identified as var. menziesii; those with leaves prominently toothed, as well as plants prominently villous but with more weakly toothed leaves, are identified as var. vernonioides.
Selected References
None.
Lower Taxa
None.
