Agdestis

Agdestis is a genus of flowering plants containing a single species Agdestis clematidea, a vine native to Mexico & Central America, and introduced to Cuba, Puerto Rico, Florida, and Texas. Its common name rockroot refers to the large boulder-like root.

Taxonomy

Agdestis is usually placed in the Phytolaccaceae family. Its classification is uncertain, however, as several studies of molecular phylogenetics have found it to be possibly the sister taxon of Sarcobatus, also of uncertain classification and often placed in its own family, Sarcobataceae.
