报道了一新种，即一直被认为是安布单蕨（Haplopterisamboinensis）或安布单蕨（Haplopterisamboinensis）的书带蕨。forrestiana（H. doniana），在此被描述为Haplopteris yakushimensis。对这两个物种的宏观和微形态特征进行了比较。Chartaceous成熟的叶片，浅槽的正面肋和钝的龙骨状背轴肋是区别H。与该属其他物种的区别。本文报道了包括我们的新分类群在内的14种东亚单蕨属植物的叶绿体chlL、ndhF和matK区的系统发育。
A new species of vittarioid ferns (Pteridaceae) that has long been regarded as Haplopteris amboinensis or H. forrestiana (a synonym of H. doniana), is described here as Haplopteris yakushimensis. Both macro-and micromorphological characteristics were compared with these two species. Chartaceous matured fronds, shallowly grooved adaxial costae and obtuse carinate abaxial costae are the diagnostic characteristics that distinguish H. yakushimensis from the other species in the genus. A phylogeny based on plastid regions chlL, ndhF and matK of 14 East-Asian Haplopteris species, including our new taxon is presented here.
