Quite near B. Fraseri LUERSS. and its variety philippinense ; but distinctly 

 differs from them by the smaller fronds with entire pinnules. The occurrence 

 of this group of the genus in Formosa is very interesting. There are in all 

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

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