在香港大霧山發現一種菌生異營性植物，形態及DNA基因間隔序列分析鑒定為龍膽科的杯藥草，屬香港新紀錄植物，而其地理分佈亦首次向南擴展到香港及更低的海拔。

A mycoheterotroph was found growing on Tai Mo Shan. Morphological characters and DNA sequence of the ITS region confirmed that it is Exacum paucisquamum (Gentianaceae). It is a new record to Hong Kong and also a new low altitude and the southern-most range of its distribution in China.
