Discussion | Smilax hugeri is distinguished from S. ecirrhata and S. biltmoreana mainly by leaf morphology. Specimens from Tennessee are not sharply distinct from S. ecirrhata. J. K. Mangaly (1968) cited this as possible evidence of divergence from that species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Smilax glauca is easily recognized by its glaucous to whitened abaxial leaf surfaces, which, however, may be altered by heat in drying. It is reportedly the most weedy species of the genus. The plants tend to be evergreen in the more southern part of the distribution. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
