Available in PDF, EPUB and Kindle. Book excerpt: Dicerandra is a genus endemic to the southeastern coastal plain of the United States. Historically, generic delimitation has been based on the presence of appendages on the anthers, described as «spurs» by Bentham, and in this study that circumscription has been maintained. Apparent pollinators are the Apidae, although in extreme ranges there is a shift to the Halictidae, Bombyliidae and Sphingidae. Data from compatibility, self-compatibility and apomictic studies confirm the obligate nature of outcrossing in Dicerandra and the adaptiveness of the spur as a trigger mechanism in pollen dispersal. Epidermal cell shape, arrangement and ornamentation of anther spurs as revealed by SEM correlate with gross morphologies. In the two major complexes of the genus, exserted stamens in flag blossom corollas are oriented ventrally for sternotribic pollination whereas inserted stamens in cucullate-lobed corollas are positioned dorsally for nototribic pollinations. However, high F1 pollen viability percentages obtained in crossing experiments, as well as the discovery of natural hybrids, imply a close relationship between these two complexes.Dicerandra grows in Quercus laevis woodlands and Pinus clausa-scrub oak woodlands in Georgia and Florida on dry sandy soils classified as quartzipsamments. Two species have radiated into more mesic environments dominated by Quercus laurifolia-Q. virginiana. Hydrophilic slime cells on the exocarp of Dicerandra nutlets are theorized to aid in dispersability of fruit by water. Allopatric perennials are isolated geographically and their distant genetic relationship to annuals affirmed by data from crossing experiments. For sympatric species, pre- and postzygotic isolating mechanisms are incomplete; ultimately, linkage of genes associated with pollination syndromes is presumed to preserve species integrity. Evolution of the genus as expressed by the Wagner Groundplan Divergence Method indicates two major phyletic lines. Section Dicerandra includes the standard-lobed corolla species with exserted stamens and the new section Lecontea including D. odoratissima and D. radfordiana is established for cucullate-lobed corolla species with inserted stamens.

This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Abundantly illustrated with more than 400 color photographs and 200 detailed drawings, this comprehensive guide to the state's rare and endangered plants provides photographs and botanical illustrations in a single volume formatted for field use. More than 200 species are covered, including two dozen that are federally listed and 170-plus that are listed as Threatened, Endangered, Rare, or of Special Concern by the Georgia Department of Natural Resources. The guide is designed for easy, nontechnical identification of species in the field. Color photographs show the plants in their natural surroundings, and drawings emphasize the most distinctive parts of the plants. Packed with information about the plants as well as their habitats and management, the guide facilitates the quick recognition of rare species, encourages awareness of their distribution and ecological significance, and provides guidelines for ensuring their survival. Additional features include directions for using the guide, a map of Georgia's counties, descriptions of the natural communities of Georgia, references for further reading, a glossary of frequently used terms, and indexes of scientific and common plant names. The guide also includes a chapter by Jennifer Ceska and University of Georgia horticulture professor James Affolter, founding members of the Georgia Plant Conservation Alliance, on horticultural requirements of rare species and the role of GPCA in their protection. This is a valuable resource for students, wildflower enthusiasts, botanists, land managers, and environmental decision makers. Each species account includes: one or more full-color photographs Georgia distribution map line drawing emphasizing such key field identification characters as leaf, stem, flower, and fruit scientific and common names legal and wetland status brief nontechnical description emphasizing key field identification characters flowering, fruiting, or sporulation period description of species habitat information on best survey season range-wide distribution Georgia conservation status management guidelines information on similar species and related rare species list of references
