Colorado Flora: Western Slope describes the remarkable flora of the state, distinctive in its altitudinal range, numerous microhabitats, and ancient and rare plants. Together with Colorado Flora: Eastern Slope, Fourth Edition, these volumes are designed to educate local amateurs and professionals in the recognition of vascular plant species and encourage informed stewardship of our biological heritage.

These thoroughly revised and updated editions reflect current taxonomic knowledge. The authors describe botanical features of this unparalleled biohistorical region and its mountain ranges, basins, and plains and discuss plant geography, giving detailed notes on habitat, ecology, and range. The keys contain interesting anecdotes and introductions for each plant family. The book is rounded out with historical background of botanical work in the state, suggested readings, glossary, index to scientific and common names, references, and hundrends of illustrations. The books also contain a new contribution from Donald R. Farrar and Steve J. Popovich on moonworts. The fourth editions of Colorado Flora: Eastern Slope and Colorado Flora: Western Slope are ideal for both student and scientist and essential for readers interested in Colorado's plant life.
