摘要

在沙巴(马来西亚)和巴布亚新几内亚的高海拔生境中描述了一新种，Asplenium alleniae。先前的叶绿体位点系统发育分析表明，A. alleniae与来自新西兰的A. pauperequitum亲缘关系最近。扁桃与扁桃的区别最明显的是其较长的羽尖的渐尖。羽状叶与几对初级羽状叶和暗红棕色轴的组合将A. alleniae与马来西亚的Asplenium表面相似的物种区分开来。扁桃暂时被评估为濒危物种。

Asplenium alleniae (Aspleniaceae), a new fern species from Borneo and New Guinea

A new species, Asplenium alleniae, is described from high elevation habitats in Sabah (Malaysia) and Papua New Guinea. Previous phylogenetic analyses of chloroplast loci determined that A. alleniae was most closely related to A. pauperequitum from New Zealand. Asplenium alleniae differs from A. pauperequitum most obviously by the acuminate apices of its longer pinnae. The combination of pinnate fronds with few pairs of primary pinnae and dark red-brown axes distinguishes A. alleniae from superficially similar species of Asplenium in Malesia. Asplenium alleniae is provisionally assessed as Endangered.
