Abstract
The spores of Osmunda cinnamomea var.asiatica Fernald were cultivated with leaf mould substrate to obtain juvenile sporophytes.Morphogenesis of the initial 25 fronds of the juvenile sporophytes was well observed.The observations lead to discussion of the adaptability of the frond morphology to the environment,phylogenetic relationship among root,stem and frond,and related phylogenetic significance.
