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 hundreds 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.

In "The American Cockerell: A Naturalist's Life", botanist William A. Weber pulls together pieces of the life of T D A 'Theo' Cockerell, a man who was an internationally known scientist, a prolific writer, and a highly regarded teacher at the University of Colorado in Boulder. The elder brother of the noted scholar Sir Sydney Cockerell, Theo laboured in relative obscurity in America while his brothers and their families were basking in the limelight of smart British society. His contribution to the understanding of wild bees is monumental - he catalogued over 900 species in Colorado alone, and he assiduously collected them wherever he travelled. By 1938 he had published the names and descriptions of 5,480 new species and subspecies. He was also an early supporter of women's rights, a Morrisian socialist, an avid reader, and author of almost 4,000 published scientific papers, book reviews, and discussions of social issues.

This is an introduction and field guide to lichens in the Rocky Mountain region. It features seventy-two colour plates picturing the most common and conspicuous species to be found in the mountains and foothills of the Rockies. Many of these lichens are also common in other geographic areas, giving the book a broader utility for those interested in lichens elsewhere. In addition to the plates, A ROCKY MOUNTAIN LICHEN PRIMER contains a brief description of each species to assist in identification, along with a general introduction to lichens and their structure. The book is tailored to the novice, and includes a section on beginning a lichen collection.

The Front Range of Colorado is one of America's most famous and spectacular summer playgrounds. Not among the least of the scenic attractions to be found here are the lavish displays of wild flowers in the mountain meadows and alpine heights, the vast expanses of cool, green forested lands, the brilliant splashes of autumn colour of our aspens and sumacs, and the endless rolling grasslands of the eastern plains. There are very few places in the United States where so many types of vegetation are crowded into such a relatively small area, and where in the space of a few minutes time one may alternately bake in the climate of the desert, and shiver in the climate of the far north. Learning to recognise the plants is a first step toward understanding a flora. The species descriptions, delicate line drawings, colour photographs, plant keys, reference materials, and glossary in Rocky Mountain Flora offer an outstanding starting point for the pursuit of botany in the Rockies.
