Description
BSA Plant Images Online -
Whole mount of fragment of sporangial epidermis from a Sphagnum girgensohnii capsule subjected to high temperature acid hydrolysis. All cell walls have survived due to presence of resistant, autofluorescentwall compounds.Cell sizes,shapes, and patterns closely resemble those of Ordovician and later microfossils classified as "dispersed cuticles." This suggests that the mose ancient microfossils consisting of cellular sheets may represent some of the earliest known remains of plant sporophytic tissues.
