Smilax is a genus of about 300-350 species, found in the tropics and subtropics worldwide. In China for example about 80 are found (39 of which are endemic), while there are 20 in North America north of Mexico[1]. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and warm temperate regions of the world. Common names include catbriers, greenbriers, prickly-ivys and smilaxes. "Sarsaparilla" (also zarzaparrilla, sarsparilla) is a name used specifically for the Jamaican S. regelii as well as a catch-all term in particular for American species. Occasionally, the non-woody species such as the Smooth Herbaceous Greenbrier (S. herbacea) are separated as genus Nemexia; they are commonly known by the rather ambiguous name "carrion flowers"
