First published in 1976, Professor Corner's study is a major work of botanical scholarship and reference. The most unsatisfactory part of the classification of dicotyledons is the arrangement of their families into orders. In these volumes the author shows how important the seed is in classification. Systems of ordinal classification based on the flower are potentially misleading in as much as floral similarity is often the effect of polyphyletic convergence. A different system of classification based on the seed is outlined. The work is the result of more than thirty years' collection and study of seeds, particularly in the tropics. The account is published in two volumes. The text in this first volume has five introductory chapters leading up to the nature of the primitive arillate seed. There then follows in alphabetical order concise descriptions of the seed in families and certain of their genera. The second volume contains more than 600 original illustrations made by the author. The two volumes are unique sources of teaching and reference material for botanical institutions throughout the world.

This volume covers up-to-date notions of seed structure, processes resulting to its formation (syngamy, triple fusion etc.), as well as of postseminal development (seed dormancy and germination). Great attention has been paid to the morphological and functional aspects of fertilization process and embryo- and endospermogenesis.

Horticultural Reviews is an ongoing series presenting state-of-the-art review articles on research in the production of commercial horticultural crops: vegetables, fruits, nuts, and ornamental plants of commercial importance. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of horticultural scientists.

This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.

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.
