摘要

中华五味子:中华五味子被描述和图解为来自俄罗斯远东楚科奇和北美阿拉斯加的一种新种。该物种属于亚纲。Canalicularia Ochyra与S. agassizii Sull亲缘关系密切。& Lesq。但是在它的脉上是立即明显的，它作为一个粗壮的圆柱状的脉长外露，在叶肩有各种双层状的层状细胞。frahmium Schistidium是一种局限于白令陆架的北极物种。

Schistidium frahmianum (Bryopsida, Grimmiaceae), a new arctic species from Beringia

Schistidium frahmianum Ochyra & Afonina sp. nov . is described and illustrated as a new species from Chukotka in the Russian Far East and Alaska in North America. The species belongs within subg. Canalicularia Ochyra and is closely related to S. agassizii Sull. & Lesq. but is immediately distinct in its costa which is longly excurrent as a stout terete subula and variously bistratose laminal cells at the leaf shoulders. Schistidium frahmianum is an Arctic species restricted in its occurrence to Beringia.
