1995 was an incredible flowering year in southern Arizona; during the flowering season, groups of botanists from the Herbarium and the Department of Ecology & Evolutionary Biology made several trips to the Roskruge Mountains (Pima county), west of the Tucson mountains. This list based on those trips & is by no means complete.
