Book Description
This action plan chronicles the threats faced by wild orchids, but more importantly to critical habitats that host extraordinarily high orchid diversity and endemicity. It explores and recommends specific ways that national and local government, legislators, scientists and orchid conservationists as well as growers can all help to reverse present trends. The facts and viewpoints presented in this comprehensive document update and supplement the information available to conservation organizations and agencies through the world so that they can lobby their appropriate government offices more effectively.

Book Description
A beautiful, richly illustrated book on Europe's wild orchids - perhaps the most enigmatic and popular group in the botanical world. The orchid family (Orchidaceae), numbering some 25,000 species, is one of the world's two largest families of flowering plants. Whilst the vast majority of orchids are found in the wet tropics, Europe accommodates c.130 native orchid species which are equally arranged in dense inflorescences of great beauty. Furthermore, the adaptations encountered in some of the European species are just as fascinating as those of their tropical relatives. This book provides an introduction to the native orchids of Europe. It features four sections: 'Structure and systematics', 'Orchids and the environment', 'Orchid portraits' and 'How to learn more'. This part constitutes the bulk of the book, presenting individual genera in a sequence which reflects their most likely evolutionary relationships. Each genus is introduced by one page of text and illustrated by one or more colour plates on the following pages. The text gives information on how to recognise the genus, where it is distributed, and the estimated number of species it contains - alongside information on the range of environmental requirements and flowering times in the European species. Depending on the genus, additional information may be found on topics such as pollination biology, associated fungi, evolutionary relationships or systematic problems. Beautiful watercolour artwork accompanies the text, making this an indispensable gift for anyone interested in the natural world. Not only is it a useful field guide, it is also a beautiful art book.

Book Description
The Infinitely Varied Orchid Family provides a never-ending source of unusual plants in a range of shapes, colors, fragrances, and sizes. As the demand for interesting and unusual species increases, so too does the need for a comprehensive reference on how to grow them. This encyclopedia, written by respected botanist Isobyl la Croix, offers detailed descriptions of 1500 cultivated species in 350 genera from Acampe to Zygostates. More than 1000 photographs will aid enthusiasts in choosing new plants for their collections as well as provide accurate ID.

Book Description
Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.

Book Description
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 1 contains accounts of all the Monocotyledons, which includes those groups known informally as the 'petaloid monocotyledons' (the Liliaceae and Amaryllidaceae in the first edition, divided here among 17 families), the grasses and sedges (Gramineae and Cyperaceae), the aroids (Araceae) and the large and diverse Orchidaceae.
