 Mal. Ferns & Al!., Supplem. I, 439. 



Rliizonae scandent, scaly. Stipes to more tlian 15 cm. long, more or 

 less scaly like the racliis and costae beiieath. Barren fronds to 75 cm. long, 

 10 — 25 cm. broad; pinnae 5 — 12'/2 cm. long, ^/j — 1'/2 en. broad, often 

 falcate ai the more or less long-acnminate apex, entire, the base obliqiiely 

 cuneate-trùncate or truncate and whether or not subauriculate on the upper 

 side or on botli sides. Texture subcoriaceous; rachis narrowly winged 

 towards the apex; surfaces naked, pale-olivaceous-green or pale-olivaceous- 

 brown when dry; veins immersed though visible, pale (not reddisli). Fer- 

 tile fronds narrower or broader tlian the barren ones, to 30 cm. or more 

 broad; pinnae much contracted, 1—2 mm. broad. — If this species might 

 prove to be identical vvith the original Leptochilus lomarioides Bl., so in- 

 sufficiently described in Bl., Enum. Plant. Jav., II, 296, then Lomagramma 

 lomarioides /. Sm., as described in Bedd., Handb. Ind. Ferns, Supplem., 

 106, must be another species.

Rhizoma repens, brève, squamis griseo-brunneis, iridescentibus, subul- 

 ato-lanceolatis, acuminatis vestitum. Frondes coriaceae, glabrae, lineari- 

 lanceolatae, 20— 30 cm. longae, 10—15 mm. latae, utrinque sensim angus-
