Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.
This unique book is a collaborative effort between researchers at Rutgers University and colleagues from numerous institutions in Uzbekistan and Kyrgyzstan. It will be the first book to document more than 200 of the most important medicinal plants of Central Asia, many whose medicinal uses and activities are being described in English for the first time. The majority of the plants described grow wild in Central Asia with some being endemic, while other species have been introduced to Central Asia but are commonly used in regional plant based medicine. The book contains four introductory chapters. The first and second chapters cover the geography, climate and vegetation of Kyrgyzstan and Uzbekistan, respectively. The third chapter provides a brief history of medicinal plant use and science in Central Asia and the fourth chapter contains general information about phytochemistry. The fifth chapter comprises the bulk of the book and covers 208 medicinal plant species. Nearly all species have one or more high quality, color photographs. Three useful appendices have been included. The first is a glossary of botanical and ecological terms, the second is a glossary of chemistry terms and the third is a glossary of medical terms. During the preparation of this manuscript we found there to be a deficiency in quality reference resources for the translation of many of the technical terms associated with the different branches of science covered in this book. In order to make our job easier we compiled glossaries over the course of preparing the manuscript and have included them feeling that they will be an extremely valuable resource for readers. ​
"The Flora of Missouri project, directed by Garden Curator, Dr. George Yatskievych, is an ongoing effort to update and compile information on the state's flora. It began in 1987 as a joint effort of the Missouri Botanical Garden and the Missouri Department of Conservation. One of its main goals is a three-volume revision of former Missouri Botanical Garden curator Julian A. Steyermark's 'Flora of Missouri', first published in 1963. Missouri's ever changing plant diversity, the shifting distributions of its plant species, and the many new records of plants in the state have necessitated an expansion of Steyermark's original publication into three volumes."--
The native British flora is today relatively ant species on the continent, such as Picea impoverished. Today the British Isles has a abies (Norway spruce), did not get into Britain flora of only about 1500 species of native in time. However, we must not over flowering plants. France and Spain, each emphasize the importance of Britain being an geographically only about twice the area, island. A comparison of floras on either side have 3-4 times as many species each. The of the English Channel shows that there are comparison is more marked when consider species present in England and not in ing the endemic species, those specialities of northern France as well as vice versa. Many each geographical region which grow of the species present in northern France but nowhere else. If only normal sexual species absent from England are weeds adapted to are considered, then there are only about 13 French agriculture. Others may be limited endemic species in the British Isles while 1000 not by the sea but by the climate. species are endemic to Spain. Nevertheless, the example of Ireland, However, the poverty of the British flora is which was isolated much earlier than the rest not a unique phenomenon. The whole of of the British Isles, does show the effect of north-western Europe, an area including isolation because it does have a much poorer northern France and much of Germany and flora and fauna.
