irregular; free veinlets often directed towards the midrib. Fertile fronds nar- 

 rower and longer than the barren ones, the upper part soriferous, narrowed 

 gradually or linearly. Sori in 1 row on each side of the costa, superficial.

Rhizome wide-creeping, liliform, sparingly clothed with small, thin, lan- 

 ceolate, ciliate scales. Fronds subsessile, + 1 c.M. apart, dimorphous. Barren 

 fronds roundish-ovate or ovate-lanceolate, 1 — 1 72 c.M. long, ± ^/^ c.M. broad, 

 cuneate at the base. Texture subcoriaceous ; surfaces glabrescent ; costa pro- 

 minent on both sides; areolae immersed, in 2 rows between the costa and 

 edge. Fertile fronds narrowly linear or more generally elongate-ovate, nar- 

 rowed at the apex. Sori round, in 2 rows, occupying the nari'owed apex of 

 the fronds, intermixed with peltate scales.

Rhizome creeping, slender, clothed with linear-lanceolate, acuminate, fer- 

 rugineous, subadpressed scales. Fronds distant, the barren ones mostly short- 

 stalked, suborbicular, oval or ovate, + 1 — 4 c.M. long, ± 1 — 2 c.M. broad 

 when fully developed, the edge entire or shallowly and broadly crenate. Tex- 

 ture coriaceous; surfaces naked; veins immersed, obscure, forming 3 — 4 rows 

 of areolae on each side, with free veinlets. Fertile fronds linear, 7 — 10 c.M. 

 long, + 5 — 4 m.M. broad, narrowed gradually towards both ends, on stipes 

 nearly as long as the fronds, the edge repand, the stipes slender, the veins 

 forming 1 — 2 rows of longitudinally elongated areolae. Sori in 1 row on 

 each side near the costa, 1 to each lobe, superficial, but the position marked 

 on the upper surface of the frond.
