 VII, fig. 2. 



Rhizome wide-creeping, climbing, scaly. Fronds simply pinnate, 20 — 45 

 c.M. long, 2 — 4 c.M. broad. Leaflets 1 — 2 c.M. long, + half as broad, 

 the lower line often slightly upcurved, the point acule or rounded, the 

 upper edge straight or ± rounded, subentire or crenato-lobate. Texture 

 pellucido-herbaceous. Sori submai'ginal, large, + as broad as long, 1 to 

 each crenation, often confluent in the subentire forms when the apices of 

 the veins are joining. — Scarcely different from L. pectinata, Bl. 



War. hemiptera, : Barren fronds dimorphous (as in Teratophyllum), the 

 abnormal ones deeply pinnatifid on the upper and outer side, the lobes very 

 fine, narrowly linear, simple or 1 — 2 X forked. 



Trop. Asia, Polynesia, Mauritius.

 with lanceolate, spreading scales. Stipes 1 — 5 c.M. apart, naked, polished, ±
