Appearance
The Deparia Japonica has delicate, pale green fronds that grow up to 18 inches in length. The fronds are bipinnate, meaning that they have two rows of leaflets that are divided into smaller leaflets. The leaflets are thin, lance-shaped, and have serrated edges. The plant produces spores on the underside of the fronds in late summer, which are housed in small, round structures called sori. When the spores are mature, they are released into the air, allowing the plant to reproduce.
