Manuel A. Luján Anzola, a doctoral student at the Rancho Santa Ana Botanic Garden and Claremont Graduate University, visited the U.S. National Herbarium for two weeks in November on a 2015 Cuatrecasas Travel Fellowship Award. The award is intended to support work in the spirit of the research of José Cuatrecasas and it is open to all who would benefit from studying tropical plants in the collection.
Hosted by Pedro Acevedo, Luján studied plant specimens of the genus Clusia. He took photographs of 4,282 specimens representing about 250 different taxa of Clusia. He carefully examined a number of specimens that might represent the conspecific complement of taxa that have been described only from staminate or pistillate material, and took tissue samples of them for further analysis. He annotated 21 specimens to reflect modern taxonomic changes and identified a number of types in the general collection that will be filed in the Type Collection.
Luján also had the opportunity to work with Laurence Dorr on a study of Clusia collections from the Flora of Guaramacal National Park project. He worked with Vicki Funk and Carol Kelloff to establish a future collaboration for the study of Clusia specimens from the Biological Diversity of the Guiana Shield Program. Additionally, he studied with Kenneth Wurdack to learn about the genetic basis of the resin production system in Malpighiales. Some species of Clusia produce resin as a reward for pollinators.
