Your quick guide to identifying cacti
When you're out and about, keep this tabbed booklet by Nora and Rick
Bowers close at hand. Featuring only Southwest cacti of Arizona,
California, Nevada, New Mexico, Utah, Colorado, and Texas, the booklet
is organized by group for quick and easy identification. Narrow your
choices by group, and view just a few cacti at a time. 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.
