This differs from ordinary forms of the Australian and Tasmanian plant, 
in its smaller size, hairy rachis, more compact habit, and less coriaceous 
texture, but these are not characters on which specific distinctions can be 
based, so that I am unable to accept Mr. Baker's opinion as to its specific 
validity. See Sir Joseph Hooker’s emphatic remarks on this species,

This minute plant is a true Hymenophyllum, the involueres being dis- 
tinctly 2-valved and divided to the base when mature. They are much 
compressed, especially in the young state, and the lips have a broad margin, 
but there is no constriction ; occasionally the lips of the valves are slightly 
recurved after the discharge of the spores. It can only be distinguished 
from H. cheesemannii by the stout marginal nerve and firmer texture; the 
involucres are not constantly ciliated. 
It forms matted patches on rocks, or oceurs more sparingly amongst 
moss on trees, so that, like the preceding, it is easily overlooked. 
Plate XXI. A., 1 and 2, Hymenophyllum armstrongii, natural size; 3, fertile pinna, 
enlarged ; 4 and 5, sori, greatly enlarged.
