At times it seems as if the reader of this book must be motivated to extract its essence as are those specialized insects described therein who must travel down the convoluted channels of certain blossoms to reach their nectar. Perhaps, in this case, more pictures and fewer words would have helped clear the path and ease the journey. To those who are determined, however, the trip will have its rewards. In their attempt to reveal each flower as a ""whole community of life,"" biologists Lotus and Margery Milne discuss a variety of flowering plants, including blackberries, water lilies, orchids, sunflowers, yuccas, oak trees, cactus flowers, milkweeds and flowering grasses. Each is representative of a different environment and is discussed in terms of the aminals it attracts, the way it attracts them, and the ways in which each helps the other to survive and propagate. A careful look at the intricacies of nature.
