荻属是禾本科的一个小属,其分类地位存在争议。通过测定和从Gen Bank中提取荻属Triarrhena及其近缘植物的ITS序列,以芦苇Phragmites australis为外类群,采用MP（maximum parsimony）和NJ（neighbor-joining）分析方法进行了系统发育分析,这两种方法得到的系统发育树基本相同。荻属和芒属Miscauthus的种类形成一个单系类群;河八王Narenga porphyrocoma与芒属和荻属的植物聚在一起并构成姐妹群;白茅Imperata cylindrica与斑茅Saccharum arundinaceum聚成一小支并构成姐妹群,白茅与荻属的关系较远;荻属植物归并到芒属更为合理,不支持将荻属置入白茅属或另立一属的观点。斑茅与白茅、河八王及蔗茅Er...

Triarrhena is a small-sized gunus of Gramineae with only two species , which occurs in eastern Asia, particularly in China, but its taxonomic treatment has been a controversial matter. It was treated as an independent gunus, or a species under Miscauthus or lmperata. This study is to assess the phylogeny of Triarrhena and its related genera in Saccharinae （Gramineae） based on internal transcribed spacer （ITS） and the 5.8s coding region of the nuclear ribosomal DNA. Maximum parsimony （MP） and neighbor-joining （NJ） methods were employed t...
