Abstract: The spores of 7 species in Bartramiaceae from China were observed by light microscope (LM) and scanning electron microscope (SEM). The result shows that there are some differences among 7 species on the proximal face, the
exine ornamention and shape . By contrast , there are some similarity on size and thickness of exine. These observation will increase new information of spores for systematic analysis of Bartramiaceae .

摘要： 作者通过光学显微镜和扫描电镜观察了7 种珠藓科植物的孢子。观察结果显示: 孢子近极薄壁区的有无、形状及外壁纹饰的细微结构等方面, 在属间和种间存在一定的差异。与此同时, 这7 种珠藓科植物的孢子在大小、外壁厚度等方面表现出较大的相似性。本研究也显示孢粉学资料可以为研究珠藓科系统演
化提供可靠的依据。
