Abstract

The border area between south-eastern Yunnan, China and northern Vietnam is one of the regions with richest biological diversity including that of the fern genus (Marattiaceae). Based on the analysis of morphology and DNA sequences of multiple chloroplast regions (, , spacer and spacer), we revised (Hayata) J.M.Camus and proposed a new combination (Hayata) J.Y.Xiang & T.Wang, , which was previously regarded as a synonym of . We found support for a monophyletic including . This discovery adds two new distribution sites of , one in China (Malipo, Yunnan) and one in Vietnam (Quan Ba, Ha Giang). We suggest should be categorised as Critically Endangered (CR) species according to the criteria of IUCN.

摘要

中国云南东南部与越南北部的边境地区是生物多样性最为丰富的地区之一，其中包括蕨类植物（观音座莲科）。基于对多个叶绿体区域（、、间隔区和间隔区）的形态学和DNA序列分析，我们对（早田）J.M.卡穆斯进行了修订，并提出了一个新组合（早田）J.Y.向 & T.王，，该组合之前被视为的异名。我们发现支持一个包括的单系类群。这一发现增加了两个新的分布地点，一个在中国（云南麻栗坡），一个在越南（河江省泉拜）。我们建议根据世界自然保护联盟的标准，应被归类为极度濒危（CR）物种。
