Discussion | Varieties 5 (4 in the flora). Vitis cinerea var. tomentosa (Planchon) Comeaux is endemic to northeastern Mexico (B. L. Comeaux and J. Lu 2000). Vitis cinerea is sometimes confused with V. aestivalis; see the discussion under that species. Vitis cinerea as defined here is highly variable and is in need of field studies and phylogeographic analysis, along with its tropical relatives V. biforma Rose and V. tiliifolia. Wan Y. et al. (2013) concluded that V. cinerea is not monophyletic. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
