Abstract
An updated catalogue of the collection of primary nomenclatural types preserved in the herbarium IEB is presented. Information is provided regarding the nomenclature of 600 taxa of vascular plants (566 species, 13 subspecies, 20 varieties and 1 form) supported by 730 specimens (219 holotypes, 500 isotypes, 3 neotypes and 8 isoneotypes). Nearly 27% of the types and 33% of the taxa correspond to the Flora del Bajío y de Regiones Adyacentes.
