In Very Good+ condition, with Good dustjacket (some edgewear and rubbing). A staple reference work for botanists and nature enthusiasts exploring the diverse flora of the West Coast. The guide covers 1,492 distinct wildflower species spanning 77 plant families. Geographically, it is incredibly broad, documenting virtually all wildflowers found from British Columbia down to Baja California, and from the Rocky Mountains to the Pacific Ocean. Rather than relying purely on complex technical keys, the book utilizes the famed Peterson Identification System, which visually highlights the specific field marks (diagnostic traits) needed to distinguish one similar species from another in the wild.
