GENUS INDEX

GENUS CODE: SMILA2
GENUS SCIENTIFIC: Smilax
GENUS AUTHORITY: L.
GENUS COMMON: Greenbrier
GENUS SUMMARY: A genus of about 220 species, woody vines and herbs, subcosmopolitan in temperate and tropical regions. Our deciduous species are a monophyletic group within Smilax, with a classic eastern North American/eastern Asian disjunction, and are treated as section Nemexia or subgenus Luiste (Wilbur 2004, Fu et al. 2005). Smilax berries and shoots provide important food sources for many wildlife species, including black bears (Ursus americanus).
GENUS IDENTIFICATION: Identification notes: The carrionflowers or deciduous smilaxes (lead 1a) are sometimes mistaken for Dioscorea because of a superficial similarity. They can be readily distinguished even in vegetative condition by Smilax section Nemexia having 3 (-5) main veins, the 3 central rejoining at the leaf apex (vs. Dioscorea with 7-13 main veins), and secondary veins in a complex reticulate pattern (vs. Dioscorea with secondary veins forming simpler and largely perpendicular cross-connections between the primary veins).
