Learn to identify Northern California's wildflowers. At the cabin, in the park, or on a hike, keep this tabbed booklet close at hand. Featuring only wildflowers of Northern California, this booklet by George Oxford Miller is organized by color for quick and easy identification. When you see a wildflower in nature, open the correct colored tab and view photographs of just a few wildflowers at a time. The easy-to-use format and detailed photographs, with key markings of more than 150 species, help to ensure positive ID for even casual observers. The pocket-sized format is much easier to use than laminated foldouts, and the tear-resistant pages help to make the book durable in the field.
