Reasons for compiling this checklist are: 1) to provide a list of accepted plant names for graduate students and staff at the Rocky Mountain Herbarium (RM) involved in floristic studies in Colorado, 2) to provide relevant synonymies, based on names accepted in the Synthesis, PLANTS, Harrington, and Weber & Wittmann, etc., for cross referencing, and 3) to provide a standard list of accepted names for the Rocky Mountain Herbarium database.
