Таксономическое положение европейско-переднеазийского рода Camelina, а также его внутриродовая структура до сих пор не очень хорошо пóняты. Вместе с тем строение плодов, общий габитус растений, без сомнения, показывают значительную органичность этого рода как единой группы видов. За всё время анализа разнообразия рода никто не усомнился в его целостности и не пытался разделить данный род на несколько. Лишь во второй половине XVIII века три вида рыжика: р. посевной, р. бурачок и р. вонючий, следуя мнению C. Bauhin (1623. P. 109), были представлены в составе рода Myagrum L. -M. sativum L., M. alyssum Mill. и M. foetidum J. - P. Bergeret (Linnaeus, 1753; Miller, 1768). Однако почти в то же время H. J. N. Crantz (1762) предложил выделить из Myagrum самостоятельный род Camelina с одним видом -C. sativa (L.) Crantz. В настоящей статье представлена новая система рода Camelina с 18 принятыми и 22 синонимизированными таксонами. Отмечено, что возможным районом возникновения рода и его основного видового разнообразия явилась Юго-Западная Азия, а вторичным районом разнообразия можно назвать Европу, где формировались не только естественные виды, такие как C. pilosa, C. sylvestris, C. neglecta и C. microcarpa, но и ряд культурных, среди которых наиболее известны C. sativa, C. linicola и C. alyssum. В работе по возможности полно проведена номенклатурная типификация и процитированы доступные типовые или аутентичные гербарные материалы. Ключевые слова: род Camelina, Cruciferae, Brassicaceae, таксономическая структура, видовое разнообразие, фитогеография, типификация, подрод, секция, ряд.

The xerophilous vegetation with characteristic insect assemblages is described in the main agricultural regions and native landscapes of Turkey. Long term intensive investigations documented vast biotic degradation of soil and vegetation (commonly referred to as desertification) by overgrazing, construction, recreation etc. Two main types of xeric landscape are under investigation: 1) natural highly specific deserts, semi-deserts, dry mountain slopes and screes; and 2) anthropogenic, newly emerged, floristically impoverished desertified areas. The presence of a multi-species insect assemblage on a xerophilous plant in certain area testifies its indigenous nature, whereas the absence of the specific consortium suggests recent plant invasion. The examples of the first case are the consortia of 3-6 species of Coleoptera, mainly Buprestidae, Chrysomelidae, and Curculionoidea, on some Apiaceae, Asteraceae, Brassicaceae, Chenopodiaceae, Ephedraceae (Ephedra spp.) and Polygonaceae (Calligonum polygonoides L.). Extreme examples of anthropogenic vegetation are overgrazed wormwood steppe and semidesert which lack usually diversified coleopterous consortia, including the most characteristic of this landscape, e.g., tenebrionids, and orthopterans. Rapid disappearance of the xerophilous complexes from the extraordinarily diversified and largely uninventoried Turkish biota makes preservation of the endangered plant and animal assemblages in different climatic zones of Turkey an urgent task.

With this paper we continue a new annual series, the main purpose of which is to make significant floristic findings from Russia and neighboring countries more vi sible in Russia and abroad. In total, this paper presents new records for 24 vascular plant species from 4 Eurasian countries, obtained during field explorations, as well as during taxonomic revisions of herbarium materials. For the first time, new locali ty of Ageratum conyzoides, Salvia hispanica, Thymus rasitatus, Tulipa mongolica is recorded for Russia, Sparganium glomeratum for North Korea, Alyssum armenum for Georgia, Thymus pseudopannonicus for Kazakhstan, Cymbalaria muralis for the Asian part of Russia, Anthemis ruthenica for Siberia, Capsella orientalis, Echinops sphaerocephalus, Hera cleum sosnowskyi, Thymus elegans for Eastern Siberia, Persicaria orientalis for Western Si beria, Galatella crinitoides for the Black Soil Region, Centaurea orientalis for Zavolzhye, Silene dichotoma for the Altai Republic, Onobrychis arenaria, Symphyotrichum squamatum, Verbesina encelioides for the Republic of Dagestan, Geranium dahuricum for the Re public of Sakha (Yakutia), Koeleria spryginii for the Republic of Tatarstan, Phacelia tanacetifolia for Sakhalin, Adonis wolgensis for Novosibirsk Region. For each species, the general distribution, habitat, and taxonomy, indicating differences from related species and location are presented.
