水玉簪十一月，真菌异养型BurmanniaL.一新种描述了广东云开山自然保护区水玉簪科植物的分类学特征。该新种在形态上与B.尼泊尔湾全株呈长圆形，带白色，叶和苞片的形状，种子黄色。然而，它很容易与B区分开来。尼泊尔湾花被裂片、花被翅、种子形状和花梗长度的长圆状特征。此外，基于nrDNA的分子遗传学也有力地支持了B. decurrensis一个分类学上的新奇。提供了形态的详细描述沿着线图以及与形态相似物种的比较。此外，还讨论了其生境、分布和保护现状。
Burmannia decurrenssp. nov., a new mycoheterotrophic species of BurmanniaL. (Burmanniaceae) from Yunkaishan Nature Reserve, southwestern Guangdong Province, China, is described and illustrated. This new species is morphologically similar toB. nepalensisandB. oblongain whole plant whitish, the shape of leaves and bracts, and yellow seeds. However, it is easily distinguished fromB. nepalensisandB. oblongaby characters of perianth lobes, perianth wings, shape of seeds and length of pedicel. Moreover, molecular phylogeny based on nrDNA also strongly supported thatB. decurrensis a taxonomic novelty. A detailed description along with line drawings of the morphology and a comparison to morphologically similar species are provided. Additionally, the habitat, distribution and conservation status are also discussed.
