摘要利用姜科（Zingiberaceae） II组内含子rps16和内部转录间隔子（ITS）的DNA序列数据进行简约性分析，探讨姜科（Zingiberales）泛热带亚科（Alpinioideae）的亲缘关系。特别强调的是大属Etlingera放置在部落Alpinieae。共有50个分类群被纳入分析。结合所有数据（ITS， rps16和编码索引的280个简约信息字符）得到的严格共识树在强支持的进化枝上得到了很好的解析。Alpinioideae亚科（不包括Pommereschea和Rhynchanthus）被强烈支持为单系。该树的基部尚未确定，但一个包含高山科（Geocharis, Amomum， Hornstedtia和Etlingera）衍生属的分支得到强烈支持。将Etlingera作为Achasma、Geanthus和Nicolaia的全名也得到了强有力的支持：Etlingera是单系的，与Hornstedtia是姊妹类群。
Parsimony analyses based on DNA sequence data of the plastid group II intron rps16 and the internal transcribed spacer (ITS) were performed in order to examine the relationship of the pantropical subfamily Alpinioideae in Zingiberaceae (Zingiberales). Special emphasis was given to the large genus Etlingera placed in the tribe Alpinieae. A total of 50 taxa were included in the analysis. The strict consensus tree obtained by combining all data (280 parsimony informative characters of ITS, rps16, and coded indels) is well resolved with strongly supported clades. The subfamily Alpinioideae (excluding Pommereschea and Rhynchanthus) is strongly supported as monophyletic. The basal part of the tree is unresolved but a clade containing the derived genera of Alpinieae (Geocharis, Amomum, Hornstedtia, and Etlingera) is strongly supported. The establishment of Etlingera as the inclusive name for Achasma, Geanthus, and Nicolaia is also strongly supported: Etlingera is monophyletic with Hornstedtia as sister group.
