Flora of the Yellowstone ― A Guide to the Wildflowers, Shrubs, Trees, Ferns, and Grass-like Plants of the Greater Yellowstone Region of Idaho, Montana, and Wyoming

"The Greater Yellowstone Region is a land accented by wildflowers; from diminutive orchids, to plants that flower once every 60 years. Taken together, their forms, colors and habits are diverse and compelling. More than 400 wildflowers, grasses, shrubs and trees readily found in the Greater Yellowstone Region, including Yellowstone and Grand Teton National Parks are included here. Designed for easy use, this guide presents a clear overview of each species, complete with photos and illustrations, botanical description, preferred habitats, and interesting tidbits on the plant's ecology and cultural use. Species are organized by family; and a quick-reference guide in the front displays flowers and distinctive fruits by color. Whether you are hiking, camping, enjoying a walk, or just driving through, Flora of the Yellowstone is the field guide to take along."
