Abstract

, a newly discovered orchid from Motuo County, Xizang, China, is described and illustrated. can be distinguished from the related species and by several distinctive features: a significantly smaller staminode above the column, a distinct purplish-red lip with purplish-brown veins, pouched with erect and triangular auriculas on both sides of its mouth, and leaves with pale green and pale yellowish-green tessellations. The novelty is also well supported as a new species by molecular phylogenetic analysis. Additionally, the complete chloroplast genome of , 157,218 bp in length, was assembled and annotated. It contains an LSC region of 86,275 bp, SSC region of 949 bp and two IRs of 34,997 bp, with 120 genes, including 76 PCGs, 36 tRNA genes and 8 rRNA genes.

摘要

本文描述并展示了一种新发现的来自中国西藏墨脱县的兰花。它可以通过几个显著特征与相关物种区分开来：在蕊柱上方有一个明显小得多的退化雄蕊，有一个带有紫褐色脉纹的独特紫红色唇瓣，唇瓣袋状，口部两侧有直立的三角形耳状物，以及带有淡绿色和淡黄绿色棋盘格图案的叶子。通过分子系统发育分析，该新物种也得到了充分支持。此外，还组装并注释了该兰花的完整叶绿体基因组，其长度为157,218 bp。它包含一个86,275 bp的LSC区域、一个949 bp的SSC区域和两个34,997 bp的IR区域，有120个基因，包括76个PCG、36个tRNA基因和8个rRNA基因。
