This critical Flora provides a definitive account of the native species, naturalised species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions will enable the user to name all plants occurring in the wild, plus some ornamental trees and shrubs. For the first time detailed accounts of all the large apomictic genera are given and many infraspecific variants included. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, including information on flowering period, pollination and chromosome number. Separate descriptions are given for infraspecific taxa. Information on the status, ecology and distribution (including worldwide distribution) of the species and infraspecific taxa is also given. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features in a number of groups of plants.

Codonopsis and its allied genera, are a group of plants which are important in economy and horticulture. A Monograph of Codonopsis and Allied Genera (Campanulaceae s. str.) offers its audience comprehensive knowledge of these plants including palynology, cytology, population biology, morphological description, geographical distribution with vouchers cited, excellent ink illustrations, and color photos, and keys to genera and to species. This excellent work will facilitate identification of relevant plants, use of plant resources, assessment of endangered states, the development of conservation strategies, and will promote systematic and evolutionary research of this group. - Provides comprehensive descriptions and classifications of Codonopsis and allied genera - Richly illustrated with line drawings and high-quality color photographs - Delineates and clarifies the relationships of Codonopsis and its allied groups based on the analyses using data from external morphology, pollen morphology, chromosomes, and molecular biology

The bluebell family Campanulaceae is found throughout the world, and includes a large number of species important in ornamental horticulture. In this volume, the first thorough account of the family to be published since 1839, 84 genera are recognised, encompassing 2319 species, 391 subspecies, and 27 named hybrids, and another 8135 names are treated as synonyms. For each recognised species, subspecies, or hybrid, information is provided on its geographic distribution, life-form, and chromosome number. All this is fully documented by an encyclopaedic bibliography. As such, it is the ultimate resource from which to begin any inquiry into the family and its members.

Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.
