Rhizome wide-creeping, the scales [dense, linear-lanceolatejmembranaceous, 

 peltate at the base. Stipes rather distant, 7*/j— 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. ,Barrm fronds with 

 the •eefltral^ pinnae . pinnate— and the lowest pinnatrf^pinnate, the segments 

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

 Pertile fronds with the segments narrower, sharper toothed. Texture coria- 

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