Books by C. Leo Hitchcock

Vascular Plants of the Pacific Northwest, in five parts, offers the first complete guide, with keys, to the ferns, fern-related, and seed-bearing plants of Washington, northern Oregon, Idaho north of the Snake River plains, the mountainous western part of Montana, and southern British Columbia. Each volume gives complete regional synonymy, type collections, geographic ranges, ¿genuine¿ common names, and chromosome numbers for each species, as well as economic importance and horticultural features.Part 5 is a comprehensive guide to the composites of the Pacific Northwest, with emphasis upon the biology of the species. Attention is given to an ecological view of the species, emphasizing the concept of interaction of environment and plant population and the evolution within the latter of distinct `ecotypes.¿Part 5 is illustrated by John H. Rumely. All other volumes are illustrated by Jeanne R. Janish.

Since this volume includes many of the plants most useful as ornamentals, gardeners, both amateur and professional, will be interested in the comments concerning species suitable for cultivation in rockery, woodland, and moist or general garden areas.Illustrated by Jeanne R.

Astralagus, the largest genus and one of the most difficult, is treated by one key based on characteristics of the flower and by another based on characteristics of the fruit.Illustrated by Jeanne R.

Each volume gives complete regional synonymy, type collections, geographic ranges, ¿genuine¿ common names, and chromosome numbers for each species, as well as economic importance and horticultural features.Part 2 covers the Salicaceae through the Crassulaceae. Each species is illustrated by one to several detailed drawings at considerable magnification of such structures as the flower, fruit, and seed, as well as a habit sketch, mostly at one-half natural size. Two keys to the families of Dicotyledonae covered by Parts 2 to 5 are included. In the first, the families are initially separated into orders, largely on the basis of floral morphology, then keyed apart. The second key, which is completely artificial, utilizes such peculiarities of the various taxa as habitat, habit, duration, and foliage, as well as floral morphology. As in Parts 3 and 4, notes on the ornamental value of the trees, shrubs, and many herbs, were written in collaboration with Brian O. Mulligan, director of the University of Washington Arboretum, and Carl S. English, well-known botanist and horticulturalist.Illustrated by Jeanne R. Janish.

An unusual feature is the inclusion of a key to the species of grasses based upon vegetative features, as well as one to grass genera based primarily upon floral structures. Part 1 also includes several sections relating to the work as a whole: an Index to Plant Families, a Glossary, a key to aquatic plants based mainly on vegetative features, several pages of additions and corrections, and a general index to common, generic, and specific names.Illustrated by Jeanne R. Janish.
