Ferns and Fern Allies of the Trans-Pecos and Adjacent Areas

Ferns are usually thought of as plants of moist, humid regions, and at first glance the Trans-Pecos region of Texas, a rugged portion of the arid Chihuahuan Desert, does not appear to be a likely location for ferns and their relatives. This book presents a review of the true ferns and the related spikemosses and scouring rushes of the Trans-Pecos.
