Liverworts, (division Marchantiophyta), are any of more than 7,000 species of small non-vascular spore-producing plants. Liverworts are distributed worldwide, though they are most commonly found in the tropics area. In Thailand, liverworts have been collected and studied since 1899. The book “Liverwort genera of Thailand” by Assoc. Prof. Dr. Phiangphak Sukkharak, Department of Biology, Faculty of Science, Burapha University, provides a synopsis on the liverwort genera of Thailand, in which 520 species in 93 genera and 39 families have been reported, representing about 7% of the world’s liverwort species. The book consists of an introduction to liverworts, history of liverwort studies in Thailand, classification of liverworts in Thailand, key to genera of liverworts found in Thailand, generic descriptions, illustrations, discussion of the most important features for identification, data on the distribution and ecology, as well as the number of species worldwide and in Thailand.

Providing an update of the classic Student's Handbook by S.M. Macvicar (1926), this illustrated account of the 300 liverwort and hornwort species on the British and Irish lists is a synthesis of nearly 40 years' study. The detailed descriptions and figures, all prepared by the author, are designed to enable students of these groups to determine the morphologically variable specimens that cause so much difficulty in identification.

This is the first book to cover England's rare and threatened mosses and liverworts, collectively known as bryophytes. As a group, they are the most ancient land plants and occupy a unique position in the colonization of the Earth by plant life. However, many are at risk from habitat loss, pollution, climate change, and other factors. Britain is one of the world's best bryologically recorded areas, yet its mosses and liverworts are not well known outside a small band of experts. This has meant that conservation action has tended to lag behind that of more charismatic groups such as birds and mammals. Of the 916 different types of bryophyte in England, 87 are on the British Red List and are regarded as threatened under the strict criteria of the International Union for the Conservation of Nature. This book aims to raise awareness by providing stunning photographs--many never before published--of each threatened species, as well as up-to-date profiles of 84 of them, including status, distribution, history, and conservation measures. The book looks at what bryophytes are, why they are important and useful, and what makes them rare; it also examines threats, extinctions, ex situ conservation techniques, legislation, and the impact of the 1992 Convention on Biological Diversity. Provides the first treatment of England's rare and threatened mosses and liverworts Features stunning photographs--many never before published--of each species and many of their habitats Treats each species in a handy and attractive double-page layout Includes up-to-date profiles of 84 species, including status, distribution, history, and conservation measures Presents the first overview of English bryophyte conservation Offers invaluable guidance to people working in conservation in England, the British Isles, Europe, and beyond

For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of Progress in the Chemistry of Organic Natural Products, namely, Volumes 42 (1982) and 65 (1995). Since the publication of the latter volume, a great deal of new information has appeared on bryophytes. One example is that known sex pheromones of algae have been discovered in two liverworts, indicating that some members of the latter taxonomic group might originate from brown algae. From information provided in this volume, it is suggested that two orders of the Marchantiophyta should be combined.
