 the middle, with the margin recurved. Texture coriaceous; upper surface 

 shining, covered with whitish cretaceous dots, many of wich are arranged 

 in a close row placed at or near the margin of the frond; under side thin-

Rhizome long, woody, the scales dense, pale, rather large, broad, elliptical or 

 deltoid-ovate, with the base rounded and peltate, the apex bluntish, the edge 

 entire or erose to lacerate, membranaceous, afterwards deciduous. Stipes 

 distant, firm, erect, naked, glossy, 6—20 c.M. long, the fertile fronds often 

 on the longest stipes. Fronds 10 — 25 c.M. long, o'/a — 7 ','2 c.M. broad, vary- 

 ing from ovate-oblong to lanceolate, the apex obtuse to acuminate, the base 

 cuneate or rounded, ± slightly decurrent upon the stipe, the edge subentire 

 or ± repand, bounded by a narrow, often recurved margin. Texture very 

 coriaceous; surfaces naked, the upper covered with minute, indistinct, scat- 

 tered black dots; costa and main veins distinct, prominent and subtri- 

 quetrous beneath, the latter distinct to the edge. Fertile fronds like the barren 

 ones or longer and narrower. Sori superficial in 2 rows between the main 

 veins, 4 — 8 in a row.
