Book excerpt: Plant Biosystematics is a compendium of papers from a symposium titled "Plant Biosystematics: Forty Years Later" held in Montreal in July 1983. This collection reviews the current field of biosystematics, particularly the evolution of natural biota, and how plant biosystematics can contribute to the welfare of humans. One paper reviews biosystematics, compares new approaches, and discusses the latest trend in comparative, molecular evolution of genes. One author discusses the cytology and biosystematics concerning the discontinuities and genetic independence occurring in the evolutionary process. Another author discusses chromosome pairing in species and hybrids that includes models of chromosome pairing in diploids. The text also describes chromosome banding and biosystematics, as well as the problems of chromosome banding that should be addressed to in future research. With estimates of the number of species being threatened with extinction numbering around 20,000 one paper address the issue of conservation and biosystematics. The author suggests that more biological information should be published to avoid duplication of effort, and possibly drive scientists to have their views more widely felt. Agriculturists, botanists, conservationists, environmentalists, and researchers in the field of botany, conservation, and plant genealogy will find this book valuable.

Available in PDF, EPUB and Kindle. Book excerpt: 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 5 completes the series, and includes many important ornamental families, such as Labiatae, Solanaceae, Scrophulariaceae, Acanthaceae, Campanulaceae, and the largest family of Dicotyledons, the Compositae.
