Interesting ferns which grow in the root mass of other large, epiphytic ferns, such as asplenium and platycerium. They can be grown on their own, in a basket, or mounted.
Several fronds, 2 or 3 feet long, mounted on a 6x8x1/2″ board. These should be moved to a larger plaque or basket soon.
The common type is wavy, and about 3/4″ wide.
