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 3 covers plants from the saxifrages to the heaths, including the
dogwood, rose, and pea families. 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.
