CAMPOS-RIOS, Ma. Goreti  y  CHIANG-CABRERA, Fernando. The Varronia P. Browne (Cordiaceae, Boraginales) genus in Mexico. Polibotánica [online]. 2012, n.33, pp.01-32. ISSN 1405-2768.

Mexico has been considered a diversity center of the Cordia genus, which is restore the genre Varronia P. Browne (Boraginaceae), involving a large shrubby species group of our flora. This motivated us to update the nomenclature and disseminate the changes proposed by Miller (2007). This review is based on MEXU herbarium collection, because it has a wide national representation. It establishes the distribution of 16 Varronia species, most endemic and highly restricted distribution. For each of the species become established the nomenclatural types and synonymies. Comments are made about the distribution and habitat, and include a key for easy identification.
