Burmannia decurrens sp. nov., a new mycoheterotrophic species of Burmannia L. (Burmanniaceae) from Yunkaishan Nature Reserve, southwestern Guangdong Province, China, is described and illustrated. This new species is morphologically similar to B. nepalensis and B. oblonga in whole plant whitish, the shape of leaves and bracts, and yellow seeds. However, it is easily distinguished from B. nepalensis and B. oblonga by characters of perianth lobes, perianth wings, shape of seeds and length of pedicel. Moreover, molecular phylogeny based on nrDNA also strongly supported that B. decurrens is 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.
