Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination. This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes. Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy A world biogeographical perspective on seed dormancy and germination Ecophysiology of seeds with each type of dormancy Critical evaluation of methodology used in soil seed bank studies Germination ecology of plants with specialized habitat and life cycle types Genetic and maternal preconditioning effects on seed dormancy and germination Guidelines for doing ecologically-meaningful germination studies

Best of Show Award, Society for Technical Communication International From the East Texas swamps and forests to the Edwards Plateau canyons and the Trans-Pecos mountains, Texas hosts a surprising number of native orchids. Their exquisite beauty endears them to everyone from wildflower lovers to professional botanists and conservationists. This beautifully illustrated book presents all 54 wild orchids of Texas. The species descriptions that accompany Joe Liggio's lovely color photos discuss the plant's flowers, blooming season, pollinators, typical habitats, and range (also shown by map), including its distribution within and beyond Texas. The species are grouped by genus and also listed by color, county, and habitat for easy reference. In addition to the species accounts, the authors offer a general natural history of Texas orchids that discusses such topics as pollination and reproduction, special growing requirements, and threats to orchids from loss of habitats and careless collecting. They also describe the many orchid habitats in Texas and the species that grow in each. This wide variety of information, which has never before been collected in one volume for a general readership, makes this book the essential guide to Texas' wild orchids.

As stated many times before the purpose of Orchid Biology, Reviews and Perspectives (OB) is to present reviews on all aspects of orchids. The aim is not to balance every volume, but to make a balanced and wide ranging presentation of orchids in the series as a whole. The chapters in this, the last volume of the series, range over a number of topics which were not covered before. Singapore is justly famed for its orchids. They can be seen on arrival (or dep- ture) in its modern, highly efficient and comfortable Changi Airport and on the way from it to town. Vanda Miss Joaquim, the first hybrid to come from Singapore became its National Flower. This natural hybrid can be seen on its currency, stamps, and public and private decorations. Many excellent breeders, starting with Prof. Eric Holttum who bred the first man made hybrid (Spathoglottis Primrose), produced numerous magnificent hybrids and won countless awards in Singapore and elsewhere. These hybrids served to enrich the country’s orchid mystique. In the opening chapter of this volume Dr. Teoh Eng Soon (Western style: Eng Soon Teoh), himself a prize winning orchid breeder, grower and author writes about some of the breeders who contributed to the Singapore orchid fame. Prof. Hans Fitting was one of the best known plant physiologists of his time. As a young man he studied the effects of pollen on orchid flowers.
