短唇金线兰 Anoectochilus brevilabris
The main identification features of the short lip are : the lip lobes are nearly triangular, the tip is sharp, 3 ~ 3.3 × 6 ~ 6.4 mm ; claws narrowly folded into a short and wide triangular flange in the middle of the lip, with 3 fine teeth on each side ; talus conic, 3-3.3 mm long, medially with a pair of fleshy corpus callosum near the talus ; both sides of the anterior column each have a wide, winged appendage. Anoectochilus roxburghii ( Wall. ) Lindl.is similar to Anoectochilus roxburghii ( Wall. ) Lindl., but both sides of the middle of the Anoectochilus roxburghii 's lips have 6 ~ 8 tassel-like slit strips of about 4 ~ 6 mm in length, while both sides of the middle of the Anoectochilus roxburghii 's lips have 3 small teeth.
It is well known that Yunnan is a region of high biodiversity due to high mountains and deep valleys, humidity, tropical and subtropical forests, especially in border areas with Vietnam where orchid species are abundant. This time, Anoectochilus brevis was found in Malipo, Yunnan, which further supported its distribution record in Vietnam.
It can be seen that for the characteristic medicinal plant Anoectochilus roxburghii in Fujian and Taiwan, its plant sources are more complex. In addition to the related species recorded in the ' Flora of China ', there may be Anoectochilus plants that are poorly known or not yet recorded in China. Therefore, it is necessary to study and sort out the origin of Anoectochilus before carrying out pharmaceutical research.
Anoectochilus brevis is a terrestrial herb. The site of this discovery is a humid evergreen broad-leaved forest slope in Malipo County, Wenshan Prefecture, Yunnan Province, with an altitude of 1300-1500 m, Lu Qing, 2016-03-25, MLP2017073101.
The voucher specimens are deposited in the Herbarium of Fujian University of Traditional Chinese Medicine. |
