Growth—

The rhizome is used in traditional Chinese medicine as a medicinal herb, known as a kind of 'Gu sui bu', a medicine more commonly derived from Davallia[1]. Once dried, fertile fronds can be removed from the plant in the dormant season; the smaller, dried sterile fronds, however, should be allowed to remain, however, since they serve to trap leaves and other debris which rots down and feeds the plant[2].
