Book Description
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.

Book Description
This work will be volume 124 in the Flora Neotropica Monograph book Series, Lawrence M. Kelly (Editor-in-Chief). Flora Neotropica volumes provide taxonomic treatments of plant groups or families growing in the Americas between the Tropic of Cancer and the Tropic of Capricorn. This monograph on Panicum (Poaceae), known as panicgrass, was written by the world-leading authority on this plant group. A total of one genus and 63 species are described. It also includes information on conservation, phylogenetic relationships, taxonomic history, ecology, cytology, and anatomy, among other topics. This is the first comprehensive volume on this topic since the 1920s and is lavishly illustrated with line drawings, black and white photographs, and distribution maps.

Book Description
Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.

Book Description
Who knew there were so many bluegrasses in Mexico?ÿ This monographic study of the Mexican species of the large (500+ species), taxonomically complex, world-wide genus Poa, by Smithsonian researchers Robert J. Soreng and Paulÿ M. Peterson, revealed there were 23, including 2 new to science, and 2 previously unknown there.ÿ Two other narrow endemics were described only in the last 10 years. The Mexican species occur mainly in the mountains, and especially in the alpine.ÿ Most of the species occurrences in Mexico presumably reflect establishment during cooler climates of past glacial cycles. Today, several are living on the edge of extinction. Eleven natives are globally rare, or rare in Mexico. Breeding system diversity is high: asexual seed production is obligate in several and facultative in some others, one is dioecious, and some are gynomonoecious, several are perfect-flowered.ÿ At least 3 arrived by long-distance-dispersal from South America?s Andes; 2 aided by asexual reproduction, 1 by the capacity to self-fertilize.
