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 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.

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.
