摘要

本研究描述了中国西南部云南的一种二倍体、有性生殖的蕨类植物--金平蕨（Dryopteris jinpingensis），并绘制了插图。金平蕨（D. jinpingensis）在形态上与高黎贡山蕨（D. gaoligongensis）相似，但在拉长的披针形叶片、无柄或近无柄羽片柄以及贴生于柄基部的重叠膜质鳞片方面具有独特性。基于质体和核 AK1 基因序列的系统发育分析表明，金平猴是高黎贡山猴的姊妹。本文提供了详细的分类学描述，并附有线图，其保护状况被评估为极度濒危。

Dryopteris jinpingensis, a critically endangered diploid new species of Dryopteridaceae from Yunnan, China

Dryopteris jinpingensis, a new species of diploid, sexually reproductive ferns of Dryopteridaceae from Yunnan, southwestern China, is described and illustrated. Morphologically, D. jinpingensis is similar to D. gaoligongensis but unique in elongated lanceolate laminae, sessile or subsessile pinna stalks, and overlapping membranous scales adnate to stipe base. Phylogenetic analyses based on both plastome and the nuclear AK1 gene sequences showed that D. jinpingensis is sister to D. gaoligongensis. A detailed taxonomic description with line drawings is provided, and its conservation status is evaluated to be critically endangered.
