A phylogenetic analysis is provided for 70% of the representatives of genus Gavilea, as well as for several species of the remaining genera of subtribe Chloraeinae: Bipinnula, Chloraea and Geoblasta. Sequences from the plastid markers rpoC1, matK-trnK and atpB-rbcL and the nuclear marker ITS, were analyzed using Maximum Parsimony and Bayesian Inference. Monophyly of subtribe Chloraeinae was confirmed, as well as its position inside tribe Cranichideae. Neither Chloraea nor Bipinnula were recovered as monophyletic. Gavilea turned out polyphyletic, with Chloraeachica embedded in the genus while Gavilea supralabellata was related to Chloraea and might be a hybrid between both genera. None of the two sections of Gavilea were monophyletic, and the topologies obtained do not suggest a new division of the genus.
为 Gavilea 属的 70%代表以及其余 Chloraeinae 亚族的几个属的几个种:Bipinnula、Chloraea 和 Geoblasta 提供了系统发育分析。使用最大简约法和贝叶斯推断分析了来自质体标记 rpoC1、matK-trnK 和 atpB-rbcL 以及核标记 ITS 的序列。亚族 Chloraeinae 的单系性得到了确认,其在 Cranichideae 族内的位置也得到了确认。Chloraea 和 Bipinnula 都没有被恢复为单系。Gavilea 是多系的,Chloraeachica 嵌入在属内,而 Gavilea supralabellata 与 Chloraea 有关,可能是这两个属之间的杂种。Gavilea 的两个部分都不是单系的,所得到的拓扑结构不支持该属的新划分。
