The winged rachis, very distinct in the upper part between the 
pinnules, affords a striking character to this species and the H. ? 
ianensis ; but the present is easily recognised by its copious 
hairs, more abundant sori, and very different involucre, which 
I think may be considered entirely that of a Hemitelia, though 
in general habit it approaches nearer a true Cyathea or Also- 
phila
