Wild Potato Collecting In Mexico

This paper is a summary of a potato collecting expedition in 1947-48 to the highlands of south-central Mexico. It is concerned almost entirely with my field work in Mexico and includes my observations in relation to the occurrence and distribution of tuberous Solanums found in that country. At a later date a paper treating the identification and taxonomy of the collections made, as well as an evaluation of all other available herbarium specimens, will be published
