Light-and electron-microscopic studies on the fine structures of spore-walls in Japanese Cyrtomium(Filicales, Aspidiacea) II

Abstract

In the present report, the fine structure of the sporewall of the Japanese Cyrtomium ; C. vittatum H. Chr., C. tachiroanum (Luerss.) C. Chr. and a from of C. falcatum (L. F.) Pr., were observed by both light-and electron-microscopes. The results are summarized in tabl 1. The spore-wall of those species mentioned above were not clearly distinguished by each other with light-microscopic observations, but their fine structures were able to be distinguished with electron-microscopic observations.
