Data from: Generic and subtribal relationships in Neotropical Cymbidieae (Orchidaceae) based on matK/ycf1 plastid data

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.

本研究基于289个分类单元的matK/ycf1质体序列联合数据，对新热带树兰族（Neotropical Cymbidieae，兰科Orchidaceae）各亚族间的系统发育关系进行了推断。研究采用RAxML对序列比对矩阵开展系统发育分析。自举法（Bootstrap, BS）分析结果显示，除吊桶兰亚族（Stanhopeinae）的自举支持值为87%外，其余所有亚族均获得100%的BS支持。亚族内的属间关系得到高度解析，且整体与既往研究及《兰科植物属》（Genera Orchidacearum）中总结的结果一致。亚族间的系统发育关系在很大程度上仍未得到解析。Szlachetko提出的颚唇兰亚族（Maxillariinae）属级分类系统未获得本研究的支持。本研究发表了1个新组合：将Maxillaria cacaoensis J.T.Atwood组合至Camaridium属。
