Abstract:
Spores of 9 species of mosses were embedded in plastic and sectioned for light and electron microscopy. The presence of 4 spore wall layers was found to be of common occurrence. A comparison with pollen wall structure was made. Variations in the layers contributing to the ornamentation were noted. A multi-layered intine was observed in the genus Archidium. The results indicate that thin sectioning should yield additional sporoderm characteristics of systematic value.
