This useful manual provides a means for easy identification of the native and cultivated conifers of northeastern North America. The territory covered is roughly eastern Canada and the northeastern fourth of the United States, from Maine south to the southern border of Pennsylvania, west to Kansas, and north to North Dakota. Because it includes so many cultivated species, the book treats the great majority of conifers found in the western United States and Europe as well. Twenty-seven genera and 130 species are included.

This major expansion and revision of W. C. Muenscher's popular reference work brings a wealth of botanical knowledge up to date in an easy-to-access format. Muenscher's Keys to Woody Plants enables its users to identify trees and shrubs in all seasons by means of diagnostic field characteristics including leaves, fruits, buds, twigs, and bark.Keys to Woody Plants was first published privately in 1922; Cornell University Press published the sixth edition in 1950. The new and expanded version of this classic identification tool for horticulturists, botanists, foresters, and ecologists treats 335 genera and 1,156 species of woody plants found in the northeastern United States. This is more than double the number covered by Muenscher's sixth edition and includes 570 cultivated species. Edward A. Cope's revision:* teaches concepts and terms necessary to all botanical identification* retains the simple structure of Muenscher's original keys* brings the nomenclature into line with current use* provides both a comprehensive key—including native, introduced, and cultivated species—and, for ease of use in the field, a separate key devoted to native and naturalized introduced species.*meets the needs of both novices and seasoned professionals * includes a bibliography of resources that allow the reader to move beyond identification and learn more about the woody plants

Описание: Abstract: Codonan the (Martius) Hanstein and Nematanthus Schrader (Gesneriaceae) are morphologically distinct genera of the evergreen and deciduous rain forests of Central and South America. Two subgenera and two sections had been recognized to accommodate the fourteen cultivated species of Cod on an the, whereas no subgeneric ranks were previously reported for the ten cultivated species of Nematanthus . Hybridizations between Codonanthe and Nematanthus have produced progeny that display a high degree of fertility, indicating that the species of Codonanthe and Nematanthus are closely related. The present study examined the species of Codonanthe and Nematanthus and attempted to resolve the relationship of species between genera and within each genus. Conventional taxonomic methods and systematic techniques of light and electron microscopy, microtomy, leaf clearings and karyology were utilized in the study of live plant material. Flowers of Codonanthe species have obliquely funnel form-ventricose corollas that are primarily white and are presumably pollinated by Euglossine bees, whereas species of Nematanthus have pouched corollas that are basically orange, red, pink or yellow and are presumably pollinated by hummingbirds. Possession of such differing corolla types and pollinators reproductively isolate these two genera, possibly indicating that Codonanthe and Nematanthus should remain as distinct taxa. Species of subgenus Codonanthe section Codonanthe have orange berries, a diploid chromosome number of n=8, and a unilacunar nodal anatomy (except C. carnosa and C. gracilis ), lack extrafloral nectaries, and are indigenous to southeastern Brazil. Species of subgenus Codonanthe section Spathuliformae and subgenus Codonanthella have red, pink or purple berries or yellow-green fleshy capsules, a tetraploid chromosome number of n=l6, and a trilacunar, split-lateral nodal anatomy, possess extrafloral nestaries, and are geographically widespread from southern Mexico through Central America to northern South America. Nematanthus crass ifolius, N. fissus, N. fritschii, N. hirtellus, N. maculatus and N. perianthomegus have a shrubby growth habit, trilacunar, spilt-lateral nodal anatomy, and resupinate flowers, whereas N. gregarius, N. nervosus, N. strigillosus and N. wettsteinii have a viny growth habit, unilacunar nodal anatomy, and nonresupinate flowers.On the basis of these observations, sections Nematanthus and Farvifolius are established to accommodate the species of Nematanthus, and it is acknowledged that further studies are required before any conclusions are made on the relationships of the infrageneric taxa of Codonanthe . A synopsis of the infrageneric taxa and revised classification of the genera Codonanthe and Nematanthus is presented Dissertation Discovery Company and University of Florida are dedicated to making scholarly works more discoverable and accessible throughout the world.

Описание: A richly illustrated collection of herbal fact and lore that illuminates the ""why"" rather than the ""how"" of the historical kitchen garden. Rather than offering a how-to of gardening methods, Kay Moss and Suzanne Simmons trace herbs and their uses back to earlier times and places.

Описание: Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation, urbanization, and land clearing through deforestation and brush fires. In order to conserve biodiversity in plants, it is important to targets three independent levels that include ecosystems, species and genes. Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. Chapters in this book are written by leading geneticists, molecular biologists and other specialists on relevant topics on genetic erosion and conservation genetic diversity in plants. This divisible set of two volumes deals with a broad spectrum of topics on genetic erosion, and approaches to biodiversity conservation in crop plants and trees. Volume 1 deals with indicators and prevention of genetic erosion, while volume 2 covers genetic diversity and erosion in a number of plants species. These two volumes will also be useful to botanists, biotechnologists, environmentalists, policy makers, conservationists, and NGOs working to manage genetic erosion and biodiversity.
