Observations on Spore Morphology of Four Species of Selaginellaceae from Xizang (Tibet)

Key Points

This research aims to observe and describe the morphological characteristics of megaspores and microspores in four species of Selaginellaceae.
Observed megaspores and microspores under light microscopy and SEM.
Analyzed ornamentation patterns and morphological features across four species: Selaginella bomiensis, S. megaphylla, S. mutensis, and S. nummularifolia.
Conducted detailed examination of species for systematics and palynology.
Identified distinct morphological features among the four Selaginellaceae species.
SEM revealed complex surface ornamentation, which varies significantly between species.
Findings contribute to the understanding of spore morphology, aiding in species identification and systematics.

Abstract

The megaspores and microspores of four species of Selaginellaceae — Selaginella bomiensis Ching et S.K.Wu, S. megaphylla Baker, S. mutensis Ching and S. nummularifolia Ching — from Xizang (Tibet) were observed for morphological features under light microscopy and scanning electron microscopy (SEM). The SEM studies showed complex ornamentation on the surface and distinct differences in the four species. The tool may be an important basis for the identification of species and contribute to the materials for systematics study and palynology of Selaginellaceae. Spore morphology of the four Selaginella is covered in detail.
