Book excerpt: The Mojave Desert eco-region extends from eastern California to northwestern Arizona, southern Nevada, and southwestern Utah, and boasts plant communities as diverse as alkali sinks, dune systems, Joshua tree woodland, pinyon juniper woodland, mixed mojave scrub, and even riparian woodland. This fully updated and revised edition will be appreciated not only by amateur wildflower enthusiasts, but experts will also find the detailed photographs and charts useful in distinguishing among similar species in difficult groups. Species are arranged by color and plant family for easy identification. This guide features 300 of the common species, full-color photographs (many brand new to this edition), detailed descriptions, information on bloom season, and interesting facts about each plant.
