"Botany in a Day is changing the way people learn about plants! Tom's book has gained a nationwide audience almost exclusively by word-of-mouth. It is now used as a text and recommended by herbal and wilderness schools across North America. Instead of presenting individual plants, Botany in a Day unveils the patterns of identification and uses among related plants, giving readers simple tools to rapidly unlock the mysteries of the new species they encounter throughout the continent."--From the publisher.
