Book excerpt: Throughout the nineteenth and twentieth centuries, wall charts were a familiar classroom component, displaying scientific images at a large scale, in full color. But it's only now that they've been superseded as a teaching tool that we have begun to realize something their ubiquity hid: they are stunning examples of botanical art at its finest. This beautifully illustrated oversized book gives the humble wall chart its due, reproducing more than two hundred of them in dazzling full color. Each wall chart is accompanied by captions that offer accessible information about the species featured, the scientists and botanical illustrators who created it, and any particularly interesting or innovative features the chart displays. And gardeners will be pleased to discover useful information about plant anatomy and morphology and species differences. We see lilies and tulips, gourds, aquatic plants, legumes, poisonous plants, and carnivorous plants, all presented in exquisite, larger-than-life detail. A unique fusion of art, science, and education, the wall charts gathered here offer a glimpse into a wonderful scientific heritage and are sure to thrill naturalists, gardeners, and artists alike.
