Rather than breaking down the plant kingdom by biome, usage, or type, this series spotlights unusual or useful plants by continent. Europe includes spreads on rootless duckweed and reindeer lichen, for example, while the gum tree and strangler fig are among species highlighted in Australasia . The books are entertaining and informative, well designed and well illustrated, and include small but clear maps. While their scope is certainly unusual, they do not shed particular light on details such as plant families or life cycles. An interesting addition for botany enthusiasts.
