ON THE ANATOMY OF THE ENDANGERED PLANT SPECIES ASPLENIUM LEPIDUM (ASPLENIACEAE)

Studies of the endangered fern species Asplenium lepidum revealed new data and features on the anatomical structure of the adventitious root, the rhizome and the leaf (petiole, rachis and pinnulae). The structures of the petiole and rachis were analysed on serial cross sections, beginning from the base up to the rachis tip, with special attention to the changes and organisation in the vascular system.
