few distant glands or auricles. Fronds ovate-lanceolate, 60 — 90 c.M. long, 

 20 — 50 c.M. broad. Pinnae numerous, the lower ones sterile, stalked, jointed 

 at the base, alternate, rather distant, 7 — 15 c.M. long, S'/j — 8 c.M. broad, 

 ovale, acuminate, the stalks provided at the base with a stipule- or auricle- 

 like outgrowth. Upper pinnae fertile, distant, 10 — 15 c.M. long, 3— 5'/s ni-M. 

 broad, short-stalked. Texture very coriaceous, rigid, thick; colour light-green; 

 racbis naked; upper surface covered with scattered, deciduous, white-creta- 

 ceous dots, lower with rather long hairs, soon naked; main veins connected

Sori indefinite, covering the whole under surface of the much contracted, 

 nearly linear fertile fronds. 



Rhizome creeping. Fronds scattered, not articulate to the rhizome, di- 

 morphous. Barren fronds simple or more generally 2-fid, the lobes sometimes 

 2-fid again; main ribs 2 or more in each lobe, uniting towards the apices 

 of the segments; veins anastomosing copiously. Diels, in Engl. & Prantl, Na^

Rhizome woody, creeping or subscandent, densely clothed with silky, 

 yellow hairs. Stipes of barren fronds ± 30 c.M. long, firm, naked. Barren 

 fronds + 20 c.M. long, 10 c.M. or more broad, the base cuneate, rounded 

 or subcordate, the upper part consisting of 2 elongate-deltoid, divaricate, 

 acute or acuminate lobes + half as long as the whole frond, sometimes 

 2-fid again. Texture coriaceous; surfaces naked; main ribs ± 4—8, 

 springing from the base of the frond, uniting towards the apices of the lobes;
