抽象的。高勒琼属是中国特有的单种属。最近在新加坡发现了一种属于该属的未描述物种的标本。通过形态学特征和系统发育分析，明确了其为高勒芥属的一个新种和第二种。本文详细描述了海南高勒青藓新种Gaolejeunea hoi sp. nov.。该新种的特征为边缘具微异格状小齿，雄蕊群基部具小苞片，雌蕊群具创新，花被具翅状侧脊。
Abstract. Gaolejeunea was previously known as a monospecific genus endemic to China. Specimens of an undescribed species belonging to the genus were recently found in Singapore. Critical assessments of morphological characters and phylogenetic analyses based on genetic sequence data of three regions (trnL-F, rbcL, nrITS) unequivocally confirmed and supported its recognition as a new and second species of Gaolejeunea. Gaolejeunea hoi sp. nov. is here fully described and illustrated. The new species is characterized by its faintly Allorgella-type marginal denticulations, the ental hyaline papilla attached to the apical margin, the bracteoles present only at the base of each androecium, gynoecia with innovation(s), perianth with wing-shaped lateral keels.
