Parsimony analyses of the tribe Naucleeae sensu lato (s.l.) using the noncoding internal transcribed spacer (ITS) regions of nuclear rDNA, the protein-coding rbcL and noncoding trnT-F regions of chloroplast DNA, and morphological data were performed to construct new intratribal classification, test the monophyly of previous subtribal circumscriptions, and evaluate the generic status of Naucleeae s.l. Fifty-two ITS, 45 rbcL, and 55 trnT-F new sequences are published here. Our study supports the monophyly of the subtribes Anthocephalidae, Mitragynae, Uncariae all sensu Haviland and Naucleinae sensu Ridsdale. There was no support for Cephalanthidae sensu Haviland and Adininae sensu Ridsdale. Naucleeae can be subdivided into six highly supported and morphologically distinct subtribes, Breoniinae, Cephalanthinae, Corynantheinae, Naucleinae, and Mitragyninae, Uncarinae, plus one, Adininae, which is poorly supported. The relationships among these subtribes were largely unresolved. We maintain the following 22 genera: Adina, Adinauclea, Breonadia, Breonia, Burttdavya, Cephalanthus, Gyrostipula, Haldina, Janotia, Ludekia, Metadina, Mitragyna, Myrmeconauclea, Nauclea, Neolamarckia, Neonauclea, Ochreinauclea, Pausinystalia, Pertusadina, Sarcocephalus, Sinoadina, and Uncaria. Pseudocinchona is reestablished. Corynanthe is restricted to C. paniculata and Hallea is reincluded in Mitragyna. Our results were inconclusive for assessing the relationships among Adina, Adinauclea, Metadina, and Pertusadina due to lack of resolution.
采用核 rDNA 的非编码内部转录间隔区(ITS)、质体 DNA 的蛋白编码 rbcL 和非编码 trnT-F 区以及形态学数据,对广义 Naucleeae 族进行简约分析,构建新的族内分类,检验先前亚族界限的单系性,并评估广义 Naucleeae 族的属的地位。这里发表了 52 个 ITS、45 个 rbcL 和 55 个 trnT-F 新序列。我们的研究支持 Anthocephalidae、Mitragynae 和 Uncariae 亚族以及 Naucleinae 亚族的单系性。没有支持 Cephalanthidae 亚族和 Adininae 亚族。Naucleeae 可分为 6 个高度支持和形态明显不同的亚族,即 Breoniinae、Cephalanthinae、Corynantheinae、Naucleinae 和 Mitragyninae、Uncarinae,加上一个支持度低的亚族 Adininae。这些亚族之间的关系在很大程度上没有得到解决。我们保留以下 22 个属:Adina、Adinauclea、Breonadia、Breonia、Burttdavya、Cephalanthus、Gyrostipula、Haldina、Janotia、Ludekia、Metadina、Mitragyna、Myrmeconauclea、Nauclea、Neolamarckia、Neonauclea、Ochreinauclea、Pausinystalia、Pertusadina、Sarcocephalus、Sinoadina 和 Uncaria。重新建立了 Pseudocinchona。将 Corynanthe 限制在 C. paniculata 中,将 Hallea 重新归入 Mitragyna。由于分辨率不足,我们对 Adina、Adinauclea、Metadina 和 Pertusadina 之间的关系的结果没有定论。
