Discussion | Lathyrus latifolius is widely naturalized in North America and forms large thickets along roadsides, especially in the Pacific Coast states. M. J. W. Godt and J. L. Hamrick (1991) explored genetic variation within the species as it occurs in North America. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
