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.) |
Normally, the peduncle of Smilax rotundifolia is about the same length as the petiole of the subtending leaf. In exceptional cases, the peduncle may be considerably longer, thereby making this widely distributed species difficult to distinguish from S. bona-nox and S. tamnoides. It lacks the marginal cartilaginous band found on the leaves of the former species and the hispid prickles of the stem of the latter. Specimens of S. tamnoides lacking prickles may be distinguished by their more strongly ridged stems. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
