Sonoran Desert Wildflowers

This bestselling field guide includes informative descriptions and excellent color photographs of more than 300 Sonoran Desert wildflowers. The flowers are arranged by color and these colors correspond to thumb marks at the top of each page. The thumb marks make it easy for a person to narrow their search and identify plants quickly in the field.  A ruler (featuring both inches and centimeters) hugs the edge of the back cover: another helpful feature for field identification. An extra-durable binding and water resistant finish also make this an ideal book to keep in your daypack throughout the spring and summer blooming seasons.
