Rhizome wide-creeping, the scales dense, linear-lanceolate, membranaceous, 

 peltate at the base. Stipes rather distant, 7^/2 — 20 c M. long, sparingly co- 

 vered with long, thin scales especially near the base. Fronds deltoid to 

 lanceolate-ovate, 10 — 20 c.M. long, 7 — 10 c.M. broad. Barren fronds with 

 the central pinnae pinnate and the lower pinnae 2-pinnate, the segmenls 

 oblong, crenate (scarcely toothed), united at the base by a narrow wing. 

 Fertile fronds with the segmenls narrower, sharper toothed. Texture coria- 

 ceous. Sori placed on the teeth. — Near H. repens, Diels, and alpina, Moore.
