The blueberry tribe Vaccinieae (Ericaceae) is particularly diverse in South America and underwent extensive radiation in Colombia where many endemics occur. Recent fieldwork in Colombia has resulted in valuable additions to the phylogeny and as well in the discovery of morphologically noteworthy new species that need to be phylogenetically placed before being named. This is particularly important, as the monophyly of many of the studied genera have not been confirmed. In order to advance our understanding of the relationships within neotropical Vaccinieae and advice the taxonomy of the new blueberry relatives, here we present the most comprehensive phylogenetic analysis for the Andean clade. Anthopterus, Demosthenesia, and Pellegrinia are among the putative Andean genera recovered as monophyletic, while other eight Andean genera were not. The analyses also showed that genera that have been traditionally widely defined are non-monophyletic and could be further split into more discrete groups. Four newly discovered Colombian Vaccinieae are placed in the monophyletic Satyria s.s. and the Psammisia I clade. Although these new species are endemic to the Colombian Western Cordillera and Chocó biogeographic region and three are not known outside of Las Orquídeas National Park, they do not form sister pairs.
越橘族（杜鹃花科）在南美洲尤为多样，并在哥伦比亚经历了广泛的辐射演化，那里有许多特有物种。最近在哥伦比亚的实地考察为系统发育研究增添了有价值的内容，同时还发现了形态上值得注意的新物种，在命名之前需要对其进行系统发育定位。这一点尤为重要，因为许多已研究属的单系性尚未得到证实。为了增进我们对新热带越橘族内部关系的理解，并为新的越橘近缘物种的分类提供建议，在此我们展示了对安第斯分支最全面的系统发育分析。Anthopterus、Demosthenesia和Pellegrinia等被认为是安第斯属的类群被恢复为单系类群，而其他八个安第斯属则不是。分析还表明，传统上宽泛定义的属并非单系的，可进一步细分为更离散的类群。四个新发现的哥伦比亚越橘物种被归入单系的狭义Satyria属和Psammisia I分支。尽管这些新物种是哥伦比亚西部科迪勒拉山脉和乔科生物地理区域的特有物种，且其中三个仅在拉斯奥奎德亚斯国家公园内被发现，但它们并非姊妹对。
