DOWNLOAD EBOOKFirst 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.

DOWNLOAD EBOOKThis is the only comprehensive account of all eight species in the genus Adansonia. It describes the historical background from the late Roman period to the present. It covers the extraordinary variety of economic uses of baobabs. There are also appendices on vernacular names, gazetteer, economics, nutrition and forest mensuration. This book fills a gap in the botanical literature. It deals with a genus that has fascinated and intrigued scientists and lay persons for centuries.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKCOMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.
