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.

"This highly synthetic and scholarly work brings together new and important scientific contributions by leading experts on a rich diversity of topics concerning the history, ecology, and conservation of California's endangered grasslands. The editors and authors have succeeded admirably in drawing from a great wealth of recent research to produce a widely accessible and compelling, state-of-the-art treatment of this fascinating subject. Anyone interested in Californian biodiversity or grassland ecosystems in general will find this book to be an invaluable resource and a major inspiration for further research, management, and restoration efforts."—Bruce G. Baldwin, W. L. Jepson Professor and Curator, UC Berkeley "Grasses and grasslands are among the most important elements of the California landscape. This is their book, embodying the kind of integrated view needed for all ecological communities in California. Approaches ranging across an incredibly broad spectrum -- paleontology and human history; basic science and practical management techniques; systematics, community ecology, physiology, and genetics; physical factors such as water, soil nutrients, atmospherics, and fire; biological factors such as competition, symbiosis, and grazing -- are nicely tied together due to careful editorial work. This is an indispensable reference for everyone interested in the California environment."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, UC Berkeley "The structure and function of California grasslands have intrigued ecologists for decades. The editors of this volume have assembled a comprehensive set of reviews by a group of outstanding authors on the natural history, structure, management, and restoration of this economically and ecologically important ecosystem."—Scott L. Collins, Professor of Biology, University of New Mexico

Detailed descriptions and drawings of caryopses are presented for 35 species representing 18 genera in the Triticeae. We studied the morphological variation in non-embryo characters involving the length, shape, compression, lateral ridges, sulcus development, coronas, and apical hairs of the caryopsis. Based on shared characters of the caryopses, we recognize three groups of genera as two major subtribes and one monogeneric subtribe. The Hordeinae includes Agropyron, Crithopsis, Elymus, Elytrigia, Eremopyrum, Hordelymus, Hordeum, Leymus, Psathyrostachys, and Taeniatherum; Triticinae includes Aegilops, Amblyopyrum, Dasypyrum, Heteranthelium, Secale, and Triticum; and Henrardiinae includes Henrardia. Similarities among the caryopses of 14 species of Elymus, Elytrigia, Leymus, and Psathyrostachys support a broad interpretation of Elymus. The caryopses of Brachypodium resemble those of the genera in the Hordeinae and to some extent Bromus.

Grasses of the Intermountain Region is a modification of the two grass volumes of the Flora of North America (FNA). It is designed for identifying members of the Poaceae in the region between the Sierra Nevada and Rocky Mountains, and is intended for use by botanists working with the grasses in this intermountain region of North America. The reduction in number of taxa included from FNA has reduced the length of the keys and made it possible to include, in a single volume, descriptions and illustrations for all taxa treated as well as provide distribution maps for species that are established in the area. Another difference from the FNA volumes is that the maps in this volume show only records from IMR and adjacent areas rather than the full North America range of the taxa.
