Discussion
Variety latifolium is generally more southern than var. lanceolatum. It is present in the southern Atlantic and Gulf coastal plain states where the latter is absent. In the southern states it is present inland and not on the coastal plains. The report of this variety for southern Quebec remains to be confirmed.
Selected References
None.
