The study on sporangial arrangement patterns in strobili of Selaginella species from Arunachal Pradesh, India aims to provide a morphological analysis of strobili in 20 species of Selaginella. The study recorded variations in the distributional patterns of sporangia in the strobili within and among the Selaginella species. It provides a detailed description of the position and features of strobili, the number and position of microsporangia and megasporangia per strobili, the shape, size and margin of sporophylls and the number of megaspores per megasporangium which are useful in taxonomic delimitation. We provided photo plates of strobili in 20 species of the genus, 16 patterns of sporangial arrangement and a table which includes sampling details along with statistical analysis based on the size of strobili and sporophylls.

印度阿鲁纳恰尔邦卷柏属球果孢子囊排列模式研究旨在对20种卷柏属球果类植物进行形态学分析。该研究记录了卷柏属物种内部和之间的球果孢子囊分布模式的变化。它详细描述了球囊的位置和特征，每个球囊中小孢子囊和大孢子囊的数量和位置，孢子叶的形状、大小和边缘以及每个大孢子囊的大孢子数量，这些对于分类学界定很有用。我们提供了该属 20 个物种的球果照片板、16 种孢子囊排列模式以及一个包含采样详细信息以及基于球果和孢子叶大小的统计分析的表格。
