Often growing far above the ground, "air plants" (or epiphytes) defy many of our common perceptions about plants. The majority use their roots only for attachment in the crowns of larger, usually woody plants-or to objects such as rocks and buildings-and derive moisture and nutrients from the atmosphere and by collecting falling debris. Only the mistletoes are true parasites. Epiphytes are not anomalies and there are approximately 28,000 species-about 10 percent of the higher or vascular plants-that grow this way. Many popular houseplants, including numerous aroids, bromeliads, ferns, and orchids, rank among the most familiar examples. In Air Plants, David H. Benzing takes a reader on a tour of the many taxonomic groups to which the epiphytes belong and explains in nontechnical language the anatomical and physiological adaptations that allow these plants to conserve water, thrive without the benefit of soil, and engage in unusual relationships with animals such as frogs and ants.

Review

Inspired by seeing an unusual plant at a childhood birthday party that led to a distinguished academic career, David H. Benzing has devoted his lifelong research to epiphytes, the extraordinary botanical denizens of the canopy. This book represents a comprehensive text covering all facets of air plants, required reading for both professional botanists and plant-lovers alike."-Margaret D. Lowman, Director of the Nature Research Center, North Carolina Museum of Natural Sciences, and Research Professor of Physical and Mathematical Sciences, North Carolina State University, author of Life in the Treetops

More than twenty years after his highly praised technical monograph on vascular epiphytes, David H. Benzing leaves the ivory tower and publishes a book on 'air plants' for a broader audience. His enthusiasm for epiphytes is contagious; every page is filled with insights gained in a lifetime devoted to the study of these plants. Highly readable, his account is still technically correct and a very stimulating read not only for the layperson but also for any biology student or biologist with an interest in epiphytes."-Gerhard Zotz, University of Oldenburg and Smithsonian Tropical Research Institute
