Archaeobotanical studies constantly encounter the carbonized grains of grasses, cultivated and wild, but the vast diversity of wild species that are potentially present has made identification of archaeological material fraught with difficulties. This volume provides an invaluable tool for mastering these difficulties. Based on years of laboratory study of an extensive reference collection, this book gives expert guidance for the identification and interpretation of grass seeds, focusing on those species that occur in the Near East and Europe.

The grass family is one of the largest and most diverse families in the plant kingdom and is of great economic value. Grasses provide human beings and domestic animals with the main necessities of life, add diversity to the landscape and stability to the ground surface, and also provide ornamental and amenity value. The present handbook is a pictorial resource guide to the identification of different common grasses in their early growth stage. In this book, 100 of the most common grasses (palatable and unpalatable) growing in the grasslands have been characterized on the basis of the vegetative characters of the seedling. A key to the identification of the grasses at their seedling stages is provided to help easily identify the grasses at their early stage of development. Many of the grasses described in the book are cosmopolitan, and many grow worldwide. Terms used to describe a grass seedling are used with help of photographs. Different diagnostic features of the seedling—such as growth habits, types of vernation, nodes, internodes, leaf laminas, leaf tips, leaf sheaths, ligules, auricles, and collars—have been used for their identification. The descriptions and photographs enable users to successfully and easily identify these species in a field environment. The book has been divided into two main sections. The first section covers the characteristic features of the caryopses. It includes light and scanning electron microscopic features and a diagnostic key to the identification of the species. The second section deals with grass seedling morphology and provides a key to the identification of the species on the basis of early vegetative features. Each of the sections includes an introduction, materials and methods, and results, supplemented with microphotographs representing the features of identification. This handbook is the first of its kind to include so many grass species that can be authentically identified with the help of pictorial diagnostic features of the seedlings and caryopses. The identifying features are solely on the basis of morphological, micromorphological, and morphometric characters. This handbook will be an important reference book of value to students in basic grass taxonomy or ecology classes as well as to academicians, researchers, pasture management practitioners, as well as professionals working in grassland restoration.

The Tallgrass Prairie Center Guide to Seed and Seedling Identification in the Upper Midwest

Settlers crossing the tallgrass prairie in the early 1800s were greeted by a seemingly endless landscape of wildflowers and grasses, one of the most diverse ecosystems on our planet. Today, although the tallgrass prairie has been reduced to a tiny percentage of its former expanse, people are working to restore and reconstruct prairie communities. This lavishly illustrated guide to seeds and seedlings, crafted by Tallgrass Prairie Center botanist Dave Williams and illustrator Brent Butler, will insure that everyone from urban gardeners to grassland managers can properly identify and germinate seventy-two species of tallgrass wildflowers and grasses in eastern North Dakota, eastern South Dakota, southwestern Minnesota, southwestern Wisconsin, northern Illinois, northwestern Indiana, Iowa, eastern Nebraska, eastern Kansas, northwestern Missouri, and eastern Oklahoma. Williams has created a brilliant, nearly foolproof system of identification and verification. Two primary keys lead to eleven secondary keys that link to characteristic groups of tallgrass plants: seven groups for wildflowers and four groups for grasses. To identify a seedling, use the primary key to discover its place in the secondary key, then turn to that characteristic group to find your seedling. Circles on each full seedling photograph correspond to close-up photographs; triangles on these close-ups illustrate information in the text to further pinpoint identification. Drawings of leaves illuminate exact identification, and enlarged photographs of each seed provide yet another way to confirm identification. Thousands of seeds were sprouted in the Tallgrass Prairie Center’s greenhouse to provide seedlings close in size and development to those grown in the field near the end of their first season; research and photography took place over four years. Williams’s text for each species includes a thorough description, a comparison of similar species, and guidance for germination and growth. A complete glossary supports the text, which is concise but detailed enough to be accessible to beginning prairie enthusiasts. Anyone in the Upper Midwest who wishes to preserve the native vegetation of prairie remnants or reconstruct a tallgrass prairie of whatever size—from home gardens to schoolyards to roadsides to large acreages—will benefit from the hundreds of photographs and drawings and the precise text in this meticulously prepared guide.

The Colour Identification Guide to Caterpillars of the British Isles Macrolepidoptera

This is the first comprehensive photo-illustrated guide to the caterpillars of butterflies and macro-moths. The book illustrates over 850 different species, or about 95% of resident, extinct, regular or irregular immigrant species to the British Isles. All specimens are photographed in natural situations upon the relevant foodplants, including many varieties indigenous to continental Europe. Many of the species have never been illustrated as caterpillars before, either by artwork or by photography. This work has received unreserved support from the best and most competent entomologists. Though the book illustrates British species, it is most valuable for lepidopterists all over Europe and especially in North and Central Europe. Never before have so many superb colour photographs of Lepidoptera been brought together in a book. The book should appeal to anyone with an interest in European Macrolepidoptera.

Moths . . . has long been recognized as the most authoritative introduction to the moths of eastern North America. Intended for nonspecialists, but greatly appreciated by intermediate and advanced users, this book identifies and describes more than 1300 species in 59 families. The 1300 species, which include at least one in each of the 59 families present in the region, are those most likely to be encountered in eastern North America. Introductory chapters describe the anatomy and life cycle of moths and processes of collecting and preparing specimens. For each species, the book includes a description during the adult stage, the range as it was known in 1984, the flight season for adults, their relative abundance, and selected other information. Individual moths are portrayed from above, with wings extended, in 63 plates, many in color, while selected anatomical features, primarily wing shape and venation patterns, are illustrated in 76 black-and-white line drawings and photographs. Back and end matter includes a glossary of technical terms, generalized anatomical drawings, silhouettes of living moths at rest, and selected references and sources of additional information.
