The monophyly of and phylogenetic relationships within the orchid tribe Maxillarieae Pfitzer were evaluated using parsimony analyses of combined nuclear ribosomal and plastid DNA sequence data of ITS 1 and 2, matK, and the trnL intron and the trnL-F intergene spacer. Each of the separate analyses produced highly congruent but weakly supported patterns (by the bootstrap), so these were combined in a single analysis. Analysis of 90 ingroup taxa (representing ∼35% of currently recognized genera) and four outgroup taxa produced resolved and highly supported cladograms. Based on the cladograms, we recognize six subtribes: Eriopsidinae, Oncidiinae (including Pachyphyllinae, Ornithocephalinae, and Telipogoninae), Stanhopeinae, Coeliopsidinae, Maxillariinae (including Lycastinae and Bifrenariinae), and Zygopetalinae (including Cryptarrheninae, Dichaeinae, Huntleyinae, and Warreinae). Stanhopeinae were sampled most intensively; their generic relationships were highly resolved in the analysis and largely agree with currently accepted generic concepts based on morphology. Coeliopsidinae (Coeliopsis, Lycomormium, Peristeria) are sister to Stanhopeinae. Correlations are drawn among phylogeny, pollination mechanisms, and life history traits.
使用 ITS1 和 2、matK、trnL 内含子和 trnL-F 基因间隔区的核核糖体和质体 DNA 序列数据的简约分析，评估了兰科 Maxillarieae Pfitzer 族的单系性和系统发育关系。每个单独的分析都产生了高度一致但支持较弱的模式（通过自举法），因此这些模式在单个分析中结合在一起。对 90 个内类群分类群（代表目前公认的属的约 35%）和 4 个外类群分类群的分析产生了已解决且高度支持的系统发育树。基于系统发育树，我们识别出六个亚科：Eriopsidinae、Oncidiinae（包括 Pachyphyllinae、Ornithocephalinae 和 Telipogoninae）、Stanhopeinae、Coeliopsidinae、Maxillariinae（包括 Lycastinae 和 Bifrenariinae）和 Zygopetalinae（包括 Cryptarrheninae、Dichaeinae、Huntleyinae 和 Warreinae）。Stanhopeinae 被采样最密集；它们的属间关系在分析中得到了高度解决，并且在很大程度上与基于形态学的当前公认的属概念一致。Coeliopsidinae（Coeliopsis、Lycomormium、Peristeria）与 Stanhopeinae 是姐妹群。在系统发育、授粉机制和生活史特征之间进行了相关性的绘制。
