lobes. Texture papyraceous; surfaces villose throughout. Veins usually + 6 — 8 

 on each side, of which ± 4 — 5 unite with the opposite veins of adjacent lobes. 

 Sori small, medial on the veins : indusium hairy, often absent.

Rhizome creeping, bearing on regular distances groups of tufted or approxi- 

 mate fronds, the scales brown, narrow-lanceolate. Stipes 15 — 50 c.M, long, 

 those of the fertile fronds much elongated. Fronds + 25 — 45 c.M. long, 

 lanceolate. Pinnae in + 12 — 14 pairs, the barren ones o^j^ — 7 c.M. long, 

 1 — 2 c.M. broad, sessile, opposite or alternate, sometimes very close and over- 

 lapping, lanceolate, acute, erec to-patent, the base truncate, auricled on the 

 upper side and sometimes on the lower side at the base, the margin entire 

 or more or less crenate particularly towards the apex, the lower pinnae 

 not rarely deflexed; fertile pinnae shorter and generally contracted, distant. 

 Texture firm-herbaceous; rachis strigose; surfaces nearly naked but verruculose; 

 veins 3 — 5 oi\ each side, all anastomosing. Sori terminal on the veins, elon- 

 gated, soon confluent and becoming meniscioid; indusium villose or glandular, 

 at length deciduous.

Rhizome creeping, the scales narrow, lanceolate. Stipes distant, strami- 

 neous or greyish, 50 — 60 c.M. long, scaly at the base. Fronds 50 — 120 c.M. 

 long, 20 — 40 c.M. broad, deltoid-oblong. Pinnae 6 to many on each side, spreading 

 or erecto-patent, the lowest largest, short-stalked, 1 — 2*/^ c.M. broad, acumi- 

 nate, the edges cut '/s — Vi'^^Y down. Lobes oblong or subdeltoid, straight 

 or subfalcate, to + 7 m.M. long, 4 — 5 m.M. broad. Texture + herbaceous; 

 rachis and both surfaces nearly naked except on the + villose costae and 

 veins; main veins pinnate in the lobes with 5 — 12 veins on each side, the 

 2 — 3 lower veins anastomosing. Sori submarginal, nearly confined to the lobes.
