"This book is a complete review of the true ferns as well as the related spikemosses and scouring rushes of the Trans-Pecos. In a concise, readable introduction, the authors describe the region, which ranges in topography from desert floors to mountain peaks of over eight thousand feet, and the variations in climate and soils that allow ferns to survive in specific habitats. In clear language they describe the morphology, reproduction, and adaptability of ferns and fern allies."--BOOK JACKET.
