On t.p.: A field guide to Rocky Mountain wildflowers from northern Arizona and New Mexico to British Columbia. This Field Guide considers the more conspicuous plants of the Rocky Mt. area. It is essentially a guide for the outdoorsman and amateur botanist--the layman who desires information about flowers observed along the highway, near camp, on the bank of a trout stream, in a mountain meadow, or on the exposed slopes of a mountain peak...This book deals with more than 590 of the common plant species--a selection of those flowers most conspicuous or most likely to be encountered.--From About this book.
