| Abstract: | Triblemma Ching is a genus proposed by Ching Ren‐Chang in 1978, and it is composed of two species, Triblemma lancea (Thunb.) Ching and Triblemma zeylanica (Hook.) Ching. There has been much debate on the systematic position of Triblemma, and this genus has always been included in Diplazium. Here, we have described new features of tracheary elements, epidermis, spore, scale, and rachis of Triblemma revealed using light and scanning electron microscopy and proposed that Triblemma is closely related to Athyriopsis, which conflicts with the traditional viewpoint. |
