This volume is the sixth of illustrated lists of Central Asian plants (within the People's Republic of China and Mongolia) published by the Botanical Institute, Academy of Sciences of the USSR, based on the Central Asian collections of leading Russian travellers and explorers as well as of Soviet expeditions, preserved in the herbarium of the institute.
This volume provides information on horsetails, clubmosses, conifers, joint-firs and several small families of monocotyledons standing at the beginning of the system, from Typhaceae to Butomaceae as well as a supplementary bibliographic list of works on the flora of Central Asia. This volume covers 79 species belonging to 20 genera of 14 small families. In the Engler system, this volume comes immediately after the first which contained a list of ferns. Joint-firs and conifers represent the most important and interesting groups in this volume. While joint-firs fall among the main characteristic plants of wastelands, conifers represent the main species of hill forests (larch, spruce, pine and juniper).
