This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa.
Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales.
This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
Designed as a light-weight and field-portable reference booklet, Wild Edible Plants of Texas highlights the Lone Star State's most important edible wild plants. To the point and understandable, this guide best suits the prepper or outdoor enthusiast in need of a salient introduction to the field. No fluff. Just the facts.Each of the 62 entries are comprised of the following sections: Range and Habitat, Edible Uses, Medicinal Uses (when applicable), Cautions, and Special Notes. Both common and scientific names are listed. Over 130 color photos assist in identification and in many cases showcase each plant's choice edible part. Every profile is assigned a Texas-only location map and a seasonal guide on the best harvesting time. A general index is included as are a dozen photos of the state's poisonous plants.Some of the entries have a greater-than Texas range, however many are uniquely Texan, and hail from a specific region. West Texas' Chihuahuan Desert, the Hill Country of the Edwards Plateau, the Plains of the Panhandle, and the Piney Woods and Swamplands of the state's Coastal Plain all are botanically represented.The following plants are covered: Agave, Algerita, Amaranth, Arrowhead, Bastard Cabbage, Black Cherry, Blackberry, Bumelia, Cattail, Cholla, Dayflower, Devil's Claw, Dewberry, Dock, Dwarf Palmetto, Elder, Flameflower, Graythorn, Ground Cherry, Hackberry, Hickory, Indian Strawberry, Jewels of Opar, Kudzu, Lambsquarters, Lemonade Berry, London Rocket, Lotus, Madrone, Mallow, Mesquite, Mulberry, Nettle, Oak, Passionflower, Pawpaw, Pecan, Pennywort, Persimmon, Pokeweed, Prickly Pear, Purslane, Redbud, Rusty Blackhaw, Sorrel, Sow Thistle, Spring Beauty, Sugarberry, Thistle, Turk's Cap, Walnut, Wild Gourd, Wild Grape, Wild Oats, Wild Onion, Wild Plum, Wild Sunflower, Winecup, Yellow Nutsedge, Yucca (Fruit), Yucca (Stalk), and Yaupon Holly.

Laminated for durability, this lightweight guide will conveniently fold to fit into your pocket. It is the one to take on your next Great Lakes adventure!
Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.
