Rocky Mountain Flora: A Field Guide for the Identification of the Ferns, Conifers, and Flowering Plants of the Southern Rocky Mountains from

This is a compact book, though it is fairly inclusive. This book had most of the plants I saw in my Rocky Mountain travels and the keys worked reliably well. There are no species descriptions, so when you key it down to the species, you are left there in the key, with no further information. I guess this helps keep the size and weight of the book down, but then I need to carry other field guides to flush out the species information. There are a few helpful well-wrought black and white illustrations as well as a very few color photographs. The books main virtue is its keys which are admirable. Thank you Mr. Weber, I will keep bringing this field guide with me, and look forward to updates (hopefully).
