      Species name: Barnadesia spinosa L.f.
      Overview
    Barnadesia spinosa represents the Barnesiodeae, which is the basal subfamily in the Compositae (http://en.wikipedia.org/wiki/Asteraceae). Evolutionary genomic analyses of Barnadesia are useful for elucidating genetic and genomic changes associated with the origin and early diversification of the Compositae. Barnadesia spinosa is a small shrub native to the northern Andes: Peru, Equador, and Columbia). Its chromosome number and genome size are unknown.
