5 — 20 c.M. long, 4^10 c.M broad, deltoid, or ovate-deltoid, cut down 

 nearly or quite to the rachis into few to several, oblong or linear-oblong 

 segments. Segments rather close, blunt, crenate or toothed, the lowest ones 

 broader, sessile or subsessile with a narrowed base, the lower side the broadest, 

 lobed or pinnatifid, with the lobes crenate, toothed or lobed again, the upper 

 side narrow, toothed or lobed. Texture coriaceous. Sori submarginal, 1 to 

 each crenation or tooth ; indusium + orbicular, sometimes slightly and Irans- 

 versally oblong, but not much broader than deep.

Rhizome creeping, scaly. Stipes to 3 c.M. long. Fronds Vl^ — 4 c.M. 

 long, 1^2 — 3 c.M. broad, or the barren fronds not rarely smaller, cordato del- 

 toid in general outline, cut down to a narrowly winged rachis. Upper segments 

 linear-oblong, deeply inciso-dentate in the fully developed fronds, the lower 

 pair deeply inciso-pinnatifid on the lower side, those of the fertile fronds 

 narrower than in the barren ones, with the teeth sharper. Texture coria- 

 ceous; veins + prominent. Sori small, placed at the base of the small teeth. — 

 Plants suggesting H. alpina, Moore, but much smaller, with the barren fronds 

 not rarely very small and the segments nearly undivided.

Rhizome creeping, scaly. Stipe 772 — 10 c.M. long, both it and the 

 rachis rather scaly. Fronds dimorphous. Barren fronds deltoid-cordate + 

 272 — 5 c.M. each way, cut down nearly to the costa. Upper lobes oblong, 

 blunt, slightly toothed, the lower pair deeply pinnatifid below. Texture coria- 

 ceous. Fertile fronds + the same shape, but more divided, 10 — 12 '/i c.M. 

 long, 7 — 8 c.M. broad, pinnate. Upper pinnae toothed to pinnatifid, united at 

 the base by a narrow wing, linear-oblong, lower pinnae cut down nearly or 

 quite to the rachis at the base into toothed lobes or pinnulae. Sori placed 

 in the teeth. — Allied to H. repens, Diels and like this with the fertile seg- 

 ments not contracted.
