Nearest to H. flabellatum, some mountain forms of which approach it very closely, 
but separated by the much longer capillary stipes, shorter, broader, and more delicate 
fronds, and by the copious hairs. HA. ferruginewm differs in the larger size, the shape

ovate-oblong, acuminate, thin and membranous, 2-3-pinnatifid, more or

hairs. Primary pinnae oblong or rhomboidal, cut down to a broad central 
portion into numerous secondary divisions, which are simple or forked or

Sori numerous, terminating the segments, more or less immersed. Indusium
