Discussion | Varieties 2 (2 in the flora). The varieties of Clematis hirsutissima, although highly dissimilar in their extreme forms, intergrade extensively in Wyoming, Colorado, and Utah. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Clematis viticella has also been reported from Quebec, New York, and Tennessee, but the reports have not been verified. It probably should be expected elsewhere. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
