    Abstract

    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.
