摘要

摘要利用光镜和电镜对印度东北部**地区18种卷柏科植物的小孢子形态进行了研究。在18个分类群中，有5个分类群是首次使用电子显微镜进行研究。所研究的物种在微孔的大小、形状、颜色和纹饰上表现出差异。赤道直径范围为11 ~ 57µm。在4个物种中记录了显微镜的四分体形式。本科不同种间显微纹饰的差异对物种的鉴别、分类和分类学区分具有重要意义。为所研究的物种提供了识别钥匙。本研究有助于统计本科小孢子的基本资料，准确鉴定卷柏属植物的种类。对小孢子的远端和近端表面纹饰进行了统计分析。

Taxonomic Significance of Microspores in Some Selected Species of the Family Selaginellaceae from Arunachal Pradesh, India

ABSTRACT The microspores morphology of 18 species of Selaginellaceae found in Arunachal Pradesh, North East India, is studied using light microscopy and electron microscopy. Of the 18 taxa examined here, the study of five taxa is attempted for the first time using an electron microscope. The species studied exhibit variation in size, shape, color and ornamentation of the microscpores. The equatorial diameter ranges from 11 to 57 µm. The tetrad form of the microscpores is recorded in four species. The variations in the microscpores ornamentation within the species of the family are useful in identification, classification and taxonomic distinction of the species. An identification key is provided for the species under study. This research is beneficial for the enumeration of basic information of microspores of the family and for the precise identification of Selaginella species. Statistical analysis of the distal and proximal surface ornamentation of the microspores is also provided.
