Apparently a common species, on the trunks of trees, in 
woods, in the northern island of New Zealand. It bears the 
orbicular involucres of H. Javanicum, but they are not 
confined to short lateral segments as in that species :—nor is 
the shape of the involucres like that of H. crispatum. . The 
fronds are more deeply and copiously divided than either, 
more crisped, especially in the wings of the rachis and stipes, 
and the general habit is different, though difficult to be 
described in words. It seems to hold a middle rank between 
the two East Indian species just mentioned.
