We evaluated the species richness and beta diversity of epiphyllous assemblages from three selected localities in Sabah, i.e. Mt. Silam in Sapagaya Forest Reserve, and Ulu Senagang and Mt. Alab in Crocker Range Park. A total of 98 species were found and a phytosociological survey was carried out based on the three study areas. A detailed statistical analysis including standard correlation and regression analyses, ordination of species and leaves using centered principal component analysis, and the SDR simplex method to evaluate the beta diversity, was conducted. Beta diversity is very high in the epiphyllous liverwort assemblages in Sabah, with species replacement as the major component of pattern formation and less pronounced richness difference. The community analysis of the epiphyllous communities in Sabah makes possible their detailed description and comparison with similar communities of other continents.

马来西亚婆罗洲沙巴的附生附艾属组合群落结构和β多样性的研究。

我们评估了来自沙巴的三个选定地区（即山）的epi虫组合的物种丰富度和β多样性。Sapagaya森林保护区的Silam以及Ulu Senagang和Mt. 阿拉克在克罗克山脉公园。共发现98种，并根据这三个研究领域进行了植物社会学调查。进行了详细的统计分析，包括标准相关性和回归分析，使用居中主成分分析对物种和叶片进行排序以及使用SDR单纯形法评估β多样性。在沙巴的附生艾蒿组合中，β多样性非常高，物种替代是模式形成的主要组成部分，且丰富度差异不明显。
