, a new mycoheterotrophic orchid, found in Maolan National Nature Reserve in Guizhou Province, China, is described and illustrated here. The new species is close to , and but differs in having a finely pubescent rachis with fewer flowers, a finely pubescent pedicel, and a fishtail-shaped lip that is deeply bilobed to the middle of the lip, with the lobes diverging at an acute angle (45°) to each other and mesochile with many papillae. Additionally, is well supported as a new species by molecular phylogenetic results based on ITS and chloroplast genome. The chloroplast genome of the novelty, which contains an LSC region of 33,819 bp, SSC region of 5,312 bp and IRs of 46,762 bp was assembled and annotated. A key to mycoheterotrophic species in China is also provided.
本文描述并展示了一种在中国贵州省茂兰国家级自然保护区发现的新的菌根异养兰花。该新物种与[其他物种名称]相近，但不同之处在于其具微柔毛的轴上花较少，具微柔毛的花梗，以及鱼尾状的唇瓣，唇瓣在中部深深二裂，裂片以锐角（45°）相互分开，中唇有许多乳头状突起。此外，基于ITS和叶绿体基因组的分子系统发育结果有力支持了该新物种。组装并注释了该新物种的叶绿体基因组，其包含33,819 bp的LSC区域、5,312 bp的SSC区域和46,762 bp的IRs。还提供了中国菌根异养[兰花属]物种的检索表。
