China-Myanmar joint discovery of the Lanke stone genus naumon stone.

Myanmar is the world's less studied biodiversity hotspot, with rich species diversity, is currently known to be about 150 species of orchid plants in the region.
the diversity of orchid plants in the area is still far from underestimating due to economic lag, transportation difficulties and restrictions on classification.
in recent years, with the support of the Southeast Asian Biodiversity Research Center of the Chinese Academy of Sciences and the official Myanmar authorities, the research team has carried out a number of expeditions to northern Myanmar, and new species and new distributions have been reported.
, the results of the study were published in the international journal Plant Keys.
, is one of the largest genus of Lanco, with 800 to 1500 species, mainly in South, East and Southeast Asia, including the Philippines, Borneo, Australia, New Guinea, New Zealand, Myanmar has been recorded to 129 species of isheran plants.
2015, when China and Myanmar jointly conducted a field visit to the Naumont area in the northern direction of Myanmar, it was found that a stone molybdenum was attached to the trunk of the riverbank rainforest, similar in form to the anti-lip stone, the stem had branches, the flower sequence was short with 1 to 2 flowers, the flower yellow green, the lip petals with purple-red stripes or spots, the lip petals three petals, the base claws.
however, the sac is wider, the back lip is small, the front lip has 3 obvious vertical folds, and the front lip edge folds with fluff and the front end of the column wing with obvious absence and difference from the first two.
therefore, after consulting the relevant specimens, literature and peer review, the scientific research team agreed that it was a new species, so in the name of the model origin published a new species: The Naumon stone.
naumon is currently only found in the pattern of origin, in 2015-2017 for three consecutive years of scientific examination, only found this species of more than 20 strains.
with population growth and frequent human activities, the region's habitat has been severely damaged.
because the plant has high ornamental and medicinal value, it is collected and sold in large quantities.
, according to iUCN standards, the Naumon is considered a critically endangered species.
