This book presents a taxonomic account of the family of grasses (Poaceae)-one of the largest of Siberian flora-which comprises 72 genera and 440 species and subspecies.

This volume provides information about 306 species from 12 plant families of Siberia, such as Salicaceae, Corylaceae, Betulaceae, Fagaceae, Ulmaceae, Cannabaceae, Urticaceae, Santalaceae, Aristolochiaceae, Polygonaceae, Chenopodiaceae, and Amaranthaceae.

The family of grasses (Poaceae) represents one of the largest of the Siberian flora. It comprises 72 genera and 440 species and subspecies. In this text, 27 new species and subspecies are described; 17 varieties are elevated to the rank of species and 10 previously regarded as synonyms are restored; 14 species detected in the herbarium material are described for the Siberian territory for the first time. The somatic chromosome number is cited for several species and subspecies.

This volume publishes for the first time specific data for Siberia on taxonomy, chorology, ecological affinity of the species of 13 families of dicotyledonous plants: Solanaceae, Scrophulariaceae, Orobanchaceae, Lentibulariaceae, Plantaginaceae, Rubiaceae, Caprifoliaceae, Adoxaceae, Valerianaceae, Dipsacaceae, Cucuribitaceae, Campanulaceae and Lobeliaceae. Dichotomous keys have been drawn for genera and species. The text has been illustrated with maps of the geographic distribution of most of the species and with their original sketches. The book is meant for botanists, ecologists, biologists, geographers, agricultural and forestry workers, and nature conservationists.

This volume contains data on morphology, ecology, and chorology of feral species and subspecies of 31 families of flowering plants. The families have been arranged essentially according to the Engler system. Conforming to the latest views (Takhtadzhyn, Sistema magnoliofitov [System of Magnoliophyta] 1987), some families have, however, been subdivided into some smaller families. Thus, family Biebersteiniaceae has been separated from family Geraniaceae; family Zygophyllaceae s.l. is represented in Siberia by 4 smaller (in volume) families: Zygophyllaceae s. str., Rutaceae, Nitrariaceae, and Peganaceae. This critical study has provided the specific characteristics of taxonomy and chorology of 299 species and subspecies belonging to 101 genera including 6 taxa that are new for science and their diagnosis in Latin.

This volume publishes for the first time specific data for Siberia on taxonomy and distribution of feral members of 18 families. The largest families Lamiaceae (Labiatae). Diagnostic features, conditions of habitation, and geographic distribution, with maps of distribution ranges in many cases, have been provided for each species and subspecies. This information forms an essential scientific basis for conservation and utilization of the resources of the plant kingdom. The book is designed for the use of botanists specializing in various branches including resource specialists and plant introducers, specialists in environmental conservation, agronomers, teachers and students.

This book publishes for the first time data for Siberia on taxonomy, chorology, and ecological adaptations of the species of one of the largest families of dicotyledons, i.e. Leguminosae. These form 27 genera and 351 species and subspecies. Four new species have been described. Maps of plant distribution have been presented for most of the species and many have been illustrated. Flora Sibiri [Flora of Siberia] has been published in 14 volumes. This book is meant for botanists specializing in various branches including resources specialists, specialists in natural conservation, plant introducers, teachers and students of biological faculties, and regional specialists.

Rosaceae, one of the largest of angiosperms is represented in Siberian flora by 32 genera, comprising 214 species.

Presents data on Siberia's eight families of mono-cotyledons: Araceae, Lemnaceae, Commelinaceae, Juncaceae, Liliaceae, Amaryllidaceae, Iridaceae and Orchidaceae. Drawings and maps for the distribution ranges are presented for some taxa.

This book provides a vital scientific base for the utilization and conservation of the floral resources of Siberia. It covers the data on morphology, ecology and chorology of 92 genera and 558 species of Compositae growing in the Siberian wilderness.
