The Iris Family: Natural History and Classification
by Peter Goldblatt and John C. Manning
Timber Press $79.95 290 pages
Are you fascinated by irises, and want to learn more? Here’s one up-to-date and detailed reference you will want to read, to discover just how widespread and complex the plant family called Iridaceae can be, and how classification and order are established using both visible characteristics and contemporary genetics.
The iris family includes not only all varieties of irises, but also other well-known plants like crocus, gladiolus and even freesia. The authors include all known representatives in the family, along with detailed scientific information about classification, culture and pollination. Samples from all over the world are included, with detailed descriptions, line illustrations and a section of color photographs. Goldblatt and Manning are particularly experienced in discovering new species found in South Africa, where they regularly locate new iris finds in the diverse and environmentally threatened Cape ecosystems.
Irises are monocots, which means that their leaves generally resemble large blades of grass, with parallel vein lines, and long sword-like blades that are the same on both sides. Ordinarily, the leaves and flowers grow in the rainy season, store energy in the rhizome, bulb or corm during the warm season, and go dormant during dry season. Our North American irises, for instance, grow and bloom in spring, store energy in summer, then go dormant throughout the winter. The flowers, which are usually found atop a tall stalk, are colorful and showy, with some requiring special pollinators. The study of flower-pollinator dynamics alone is fascinating.
This is not a book for easy reading, nor is it a “how-to” gardening guide. If you’re new to gardening, you’ll need to learn terminology and know basic plant biology to appreciate its full value. There is a wealth of information here for iris enthusiasts and botanists, including an identification guide and key, detailed descriptions of plant forms, along with supporting natural history and cultural usage sections. In addition to the expected plant profiles, the authors have also shared details about chromosome numbers and fragrances for iris family members from Acaste venusta to Zygotritonia praecox, and hundreds inbetween.
Need a break from all that gardening you’ve been doing now that the weather oh-so-perfect?
