 differs from them by the smalle].- fronds with entire pinnules. The occurrence 

 of this group of the geuus in Formosa is veiy interesting. There are in all 

 two species and a variety ; one species exists in Newzealand, a variety of the 

 same species in the Philippines aud the other, the present one, in Formosa.
