Abstract

is described from Attu Island, Alaska, U.S.A. The newly-described species is not similar in appearance to any Northern Hemisphere species; only the habit is similar to . However, it not only occupies a different habitat than that species, but genetically and morphologically, it is clearly distinct from it. The results of DNA sequencing, a detailed description of the morphological features, illustrations, ecological preferences and currently known geographical distribution of are presented. The most important distinguishing morphological features of this species are: the size of the plant; dimensions and symmetry of the leaves; dimensions of cells and their areolation; entire leaf apex; and long decurrencies with some inflated cells. Additionally, we propose to place in section Plagiothecium, which is confirmed by genetic analysis and morphological features.

摘要

是从美国阿拉斯加的阿图岛描述的。新描述的物种在外观上与任何北半球物种都不相似；只有习性与之相似。然而，它不仅占据与该物种不同的栖息地，而且在基因和形态上，它与该物种明显不同。文中给出了DNA测序结果、形态特征的详细描述、插图、生态偏好以及目前已知的地理分布。该物种最重要的形态鉴别特征是：植株大小；叶片的尺寸和对称性；细胞尺寸及其分隔；叶尖完整；以及具一些膨大细胞的长下延部分。此外，我们建议将其归入斜蒴藓属，这一点通过遗传分析和形态特征得到了证实。
