摘要

摘要半月板藓是夏威夷考艾岛特有的单岛蕨类植物。所有的观察都表明，它是一种专性流变动物，喜欢在快速流动的水的地方，沿着遥远的溪流和瀑布边缘的凹壁。本文介绍了其形态、演化、分类、分布、丰度和生态特征。根据系统发育和地理证据，夏威夷半月板虫的祖先可能是从东亚大陆的山脉中散布出来的。IUCN对该物种的正式评估已经完成，并在这里报告为极度濒危物种(CR B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v))。

Notes on Menisciopsis wailele (Thelypteridaceae), a Critically Endangered Rheophytic Fern Species from Kaua‘i, Hawaiian Islands

Abstract. Menisciopsis wailele (Thelypteridaceae) is a single-island endemic fern species restricted to the Hawaiian island of Kaua‘i. All observations indicate it is an obligate rheophyte, preferring sites of fast-moving water along concave walls of remote streams and waterfall edges. This paper presents data on its morphology, evolution, taxonomy, distribution, abundance, and ecological characteristics. Based on phylogenetic and geographic evidence, the ancestor of the Hawaiian species of Menisciopsis may have dispersed from the mountains of continental East Asia. A formal IUCN assessment of the species has been completed and is reported here as Critically Endangered (CR B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)).
