Smilax

Smilax is a genus of about 300–350 species, found in the tropics and subtropics worldwide. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and subtropical regions of the world. Common names include catbriers, greenbriers, prickly-ivys and smilaxes. Sarsaparilla (also zarzaparrilla, sarsparilla) is a name used specifically for the Neotropical S. ornata 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.

Greenbriers get their scientific name from the Greek myth of Crocus and the nymph Smilax. Though this myth has numerous forms, it always centers around the unfulfilled and tragic love of a mortal man who is turned into a flower, and a woodland nymph who is transformed into a brambly vine.
