摘要

在达吉斯坦(俄罗斯)萨米尔森林曾报道过高加索头孢菊,但该报道被认为是可疑的:推测可能将C. damasonium和C. longifolia之间的所谓杂交品种误认为是高加索头孢菊。此外,该物种最近在«世界植物在线»数据库中被降为C. kotschyana的同义词。在本研究中,我们没有证实在萨穆尔森林中存在高加索杉木,但在俄罗斯达吉斯坦共和国Kaytagskiy地区和tabasaransky地区的山毛榉(Fagus orientalis)森林遗迹中发现了少数地方的高加索杉木。在Tatil村附近研究了活的植物,在那里统计了40个开花个体。形态学研究表明,这些植物属于典型的白种人,而不是杂交品种。该物种与C. kotschyana的同义也被拒绝,因为它与“国际藻类,真菌和植物命名法”相矛盾,而且没有适当的理由。本文确定了白桦的选型。该物种的描述提供了主要形态参数的测量。讨论了白豆属植物及其相关分类群的差异。提供了来自北高加索的头甲属物种的钥匙。根据IUCN的分类和标准,高加索头鲸在俄罗斯受到高度威胁,被估计为濒危分类群(EN B1ab(iii)+2ab(iii))。它应列入国家和区域红色数据手册的下一个版本。

On the presence of Cephalanthera caucasica (Orchidaceae) in Russia: rediscovery of a threatened orchid in the Republic of Dagestan
Cephalanthera caucasica had been reported previously from the Samur Forest in Dagestan (Russia), but that report was considered doubtful: a possible misidentification of supposed hybrids between C. damasonium and C. longifolia as C. caucasica was speculated. Moreover, this species was recently reduced to a synonym of C. kotschyana in the «Plants of the World Online» database. In the present study, we did not confirm the presence of C. caucasica in the Samur Forest, but it was revealed in a few localities in remnants of beech (Fagus orientalis) forests in Kaytagskiy district and Tabasaranskiy district in the Republic of Dagestan, Russia. Living plants were studied in the vicinity of the village Tatil where 40 flowering individuals were counted. A morphological study suggested that these plants belonged to typical C. caucasica, not to any hybrid. The synonymy of this species with C. kotschyana has also been rejected, because it contradicted to the «International Code of Nomenclature for algae, fungi, and plants» and, besides, was not properly reasoned. The lectotype of C. caucasica is designated in the present paper. The description of the species is provided with measurements of the main morphological parameters. Differences of C. caucasica and the related taxa are discussed. A key to the species of the genus Cephalanthera from the North Caucasus is provided. Cephalanthera caucasica is highly threatened in Russia, being estimated as Endangered taxon (EN B1ab(iii)+2ab(iii)), according to the IUCN categories and criteria. It should be included to the next editions of both national and regional Red Data Books.
