Abstract

New data on the distribution of Ditrichum divaricatum Mitt. are presented. This species was described from Japan and previously known also from South Korea and China; it is identified in collections from Russia (Transbaikalia, Suntar-Khayata Mt. Range in Yakutia, and the Kamchatka Peninsula) and from Alaska (USA). Most specimens from Russia were previously attributed to D. pallidum (Hedwig) Hampe but the revision of the herbarium collections in MW, MHA, and LE did not confirm the presence of the latter species in the country. A description and illustrations of D. divaricatum based on Russian specimens are provided as well as data on its ecology; in the north of the Pacific, the species is confined to volcanic substrates of acidic composition.

北太平洋地区苔藓植物dirichum divaricatum的分布

文章标题刺柳属植物分布的新资料。提出了。这个物种是在日本被描述的，以前也在韩国和中国被发现;它在俄罗斯(外贝加尔，雅库特的Suntar-Khayata山脉和堪察加半岛)和阿拉斯加(美国)的收藏中被发现。来自俄罗斯的大多数标本以前被认为是D. pallidum (Hedwig) Hampe，但对MW、MHA和LE的植物标本馆藏品的修订并未证实该国存在后者。以俄罗斯标本为基础，提供了对异花散斑蝶的描述和插图，以及其生态学数据;在太平洋北部，该物种局限于酸性成分的火山基质中。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
