Resumen:
Escallonia (Escalloniaceae) is a New World genus of c. 39 species distributed mainly in the South American highlands. Plastid DNA sequence data from the intergenic spacers trns-trnG and 3´trnV-ndhC, and from the ndhF gene for 32 species were used to examine the relationships among species and related genera, and analyse the relationship between phylogeny and the geographical distribution of the species. Maximum parsimony and Bayesian inference were employed to analyse the data. The sister relationship of Escallonia to Forgesia and Valdivia was corroborated. We recovered five highly supported clades that are geographically structured, suggesting that the evolutionary history of the genus may be linked to historical processes like the uplift of mountainous systems in South America.
