| Species name: Barnadesia spinosa L.f.|
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.

We generated the Sanger ESTs described above, which are being used to determine the distribution of whole genome duplications in the Compositae.
