Evaluating the phylogenetic relationship of Berberis species in Ecuador.

The genus Berberis has two main areas of concentration, temperate SE Asia and along the Andes in South America. The discussion of Berberis species have increased recently because of the latest wheat rust disease outbreaks in East Africa, likely resulting from the sexual recombination of the rust on its Berberis alternate host.  Only Berberis sensu stricto (simple leaves, i.e., not Mahonia) occurs in South America. More than 30 Berberis species have been reported in Ecuador, half of them endemic. However most of the herbarium collections are types that have only been found one time and /or date back 20 years or more. Therefore, the current state of the systematics and taxonomy of Berberis in Ecuador is largely unknown. Our goal is to better understand the diversity of Berberis in Ecuador. Preliminary data shows that the Ecuadorian Berberis are phylogenetically distinct from those of Argentina and Brazil. B. hallii and B. grandiflora form well supported monophyletic groups. To fully understand Berberis diversity in Ecuador, we plan to increase our collecting sampling.
