利用289个分类单元的matK/ycf1叶绿体序列数据，估算了新热带兰科(兰科)各亚族间的亲缘关系。用RAxML对该矩阵进行分析。Bootstrap(BS)分析得出，除StanHopeinae亚族(87%)外，所有亚族的BS支持率均为100%。亚族内部的属属关系是高度确定的，通常与先前研究中提出的和《兰科植物属》中总结的一致。亚族之间的关系在很大程度上还没有解决。不支持Maxillariinae的Szlachetko属分类。为茶树属(Camaridium)中的可可木(Maxillaria cacaoensis J.T.Atwood)进行了新组合。
Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.
