Book Description
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.

Book Description
A comprehensive overview of this genus, Artemisia examines all aspects of the herbs uses and applications, its mode of action and clinical importance. Following a comprehensive introduction to the genus, the book discusses the botanical, phytochemical and biological aspects of a number of important species of Artemisis. Considering that the discove

Book Description
The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Book Description
Plants growing in tropical alpine environments (at altitudes above the closed canopy forest and below the limit of plant life) have evolved distinct forms to cope with a hostile environment characterized by cold, drought and fire. Unlike temperate alpine environments, where there are distinct seasons of favourable and unfavourable conditions for growth, tropical alpine habitats present summer conditions every day and winter conditions every night. Using examples from all over the tropics, this fascinating account reviews, for the first time, the unique form and functional relationships of tropical alpine plants examining both their physiological ecology and population biology. It will appeal to anyone interested in tropical vegetation and plant physiological adaptations to hostile environment, as well as to researchers in biogeography and ecology.

Book Description
"This multifarious volume does a splendid job of reflecting the breadth and depth of fundamental questions about the methods of systematics and biogeography, from the practical applications of conservation biology to issues of wide interest to evolutionary biologists."--Dr. Norman I. Platnick, American Museum of Natural History "A fun and informative volume that everyone interested in the subject will enjoy. This book is full of important discussions on Botany, Cladistics, and Biogeography."--Vicki Funk, National Museum of Natural History, Smithsonian Institution "The Branching Of A Paradigm is the intriguing theme of this volume on the myriad of ways cladistics has impacted modern biology. Surprises from floristics to recent thoughts on epistemology await the reader."--Dennis Stevenson, New York Botanical Garden

Book Description
After the 1988 and 1989 volumes, this is the third volume on Medicinal and Aromatic Plants. Each of the 29 chapters contributed by international scientists deals with one individual plant genus, namely Atropa, Ageratina, Ailanthus, Aconitum, Apium, Aloe, Akebia, Bidens, Carthamus, Chamomilla, Carum, Citrus, Cymbopogon, Dysosma, Euphorbia, Fritillaria, Glycyrrhiza, Lavandula, Nigella, Pelargonium, Perilla, Podophyllum, Rosa, Scutellaria, Securinega, Solanum, Swertia, Symphytum, Syringa. Their distribution, economic importance, conventional propagation, in-vitro propagation and production of metabolites through tissue culture are treated in detail. Special emphasis is laid on the potential of industrial in-vitro production of plant compounds of medical and pharmaceutical relevance using tissue culture.
