This handbook is a comprehensive and detailed guide to the identification, distribution and appreciation of Arizona’s botanical wonders, the cacti and succulents.

Home to at least four distinct desert regions and multiple biomes, Arizona is a hotbed of botanical diversity, rarity and endemism. The most charismatic and breathtakingly beautiful plants in the state are featured. Designed to be detailed enough for armchair reading, but portable enough for hands on field work, this guide draws on the contributions of more than six author/photographers, all of whom are experts in Arizona field research.

The authors have traveled and re-traveled hundreds of back road miles to establish not only species distributions and expand on current knowledge in populations, but also to capture that rare moment of peak flowering. The latest taxonomic, botanical and biogeographic information has been incorporated into this extensive regional treatment which the authors hope will be useful and entertaining for years to come.
