Arizona Rare Plant Field Guide
Published in 2000 by the U.S. Government Printing Office, this book was produced by the Arizona Rare Plant Committee, a collaboration of agencies and organizations, including AZNPS.
The guide lists more than 125 species of plants that are rare in Arizona. For each species there is a description, including phenology, management responsibility, habitat, range, and notes. Beautiful drawings and color photos illustrate each species, along with a very general map. In addition, the species are listed not only by botanical name, but also by management responsibility (e.g., Coconino National Forest), and by county.
