This volume consists of text relating to how a seed is made, the structure if seeds, the characteristics of families of seeds ordered by relation resulting in families of dicotyledons.

V.1 - Seed-form; Seed-coats; Criticism of the arrangement of dicotyledonous families into orders; Seed-evolution; Descriptions of seed by families; v.2 - Material and method; Seed-form; Seed-coats; Criticism of the arrangement of dicotyledonous families into orders; Seed-evolution; Descriptions of seeds by families.

A poet and farmer aims to preserve ecological integrity through a discussion of the history, lore and importance of seeds through the ages, as important now to human sustenance as ever before, particularly in the face of the spreading use of GMOs.

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.

Black & white print. Concepts of Biology is designed for the typical introductory biology course for nonmajors, covering standard scope and sequence requirements. The text includes interesting applications and conveys the major themes of biology, with content that is meaningful and easy to understand. The book is designed to demonstrate biology concepts and to promote scientific literacy.

Dendrology: Cones, Flowers, Fruits and Seeds offers a comprehensive overview of the morphology of reproductive organs of woody plants of Europe in one resource. The book contains 2020 woody taxa (845 species, 58 subspecies, 38 varieties, 13 forms, 40 hybrids and 1026 cultivars), belonging to 400 genera and 121 families. It includes 447 taxa of trees and shrubs that are autochthonous in Europe and numerous ornamental species that originate from North America, Asia, South America, Australia and Africa, along with invasive woody species. Accompanied by thousands of original photographs, the book is designed to efficiently guide the reader to accurate identification. Other features include taxa organized in alphabetical order of their botanical names, flowering and fruiting time, mode of fruit or seed dispersal, and distribution range, making this a must-have reference for students and researchers in dendrology, botany, forestry, forest management and conservation, arboriculture and horticulture. - Includes 2,020 taxa of trees and shrubs important for the European dendrology - Provides detailed descriptions of reproductive organs and data on the reproductive biology of the described taxa - Contains 6,644 original, high-quality photographs of habits, cones, flowers, fruits and seeds

Seed Purity and Taxonomy replaces The Handbook of Seed Testing, as the most complete and up-to-date resource of information available on seed identification and seed taxonomy. Seed Purity and Taxonomy contains a comprehensive listing of seeds along with approximately 3,000 black-and-white sketches, photographs, and computer-scanned images of species most likely to be encountered in seed testing laboratories in North America. Internal morphological features of different family groups are also included. These images are complemented with detailed descriptions and numerous dichotomous keys that will help in making definitive identifications.
