Abstract

The systematics of Arundinoideae (Poaceae), a subfamily long considered as a dustbin group, has been progressively resolved in recent decades. The last members incertae sedis of Arundinoideae are two African species not observed for > 150 years and currently studied only on the basis of old herbarium specimens. Based on the sequencing of its whole plastid genome, Leptagrostis schimperiana was placed in the monophyletic Crinipedeae (Arundinoideae) in the grass plastome phylogenetic tree. To date, whole plastome sequencing based on a 167-year-old herbarium specimen is a new record. Using a morphological cladistic approach based on 51 morphological and anatomical characters, we confirmed the position of Leptagrostis schimperiana and showed that Piptophyllum welwitschii is also a member of Crinipedeae.

167岁植物标本室标本的塑性组测序和经典形态学解析了两种可能灭绝的草种的系统学

摘要

在过去的几十年中，长久以来被视为垃圾箱群的亚科-伞形科（禾本科）的系统学已得到逐步解决。Arundinoideae的incertae sedis的最后一个成员是两个在150多年内未观察到的非洲物种，目前仅根据旧的植物标本室标本进行研究。根据整个质体基因组的测序，将Leptagrostis schimperiana放置在草质体系统树的单系phyl科（Arundinoideae）中。迄今为止，基于167岁的标本室标本的整个质体组测序是一个新记录。使用基于51个形态和解剖特征的形态分类方法，我们确定了Leptagrostis schimperiana的位置，并表明Piptophyllum welwitschii也是Crinipedeae的成员。
