Assam and Malay region. 



Habit of L. (Odontoloma) repens. Beside the typical fronds, old 

 rhizomes produce finely dissected, much smaller sterile ones, resembling 

 those of Asplenium epiphyticitm and Utenochlaena [TeratophyUum) , or 

 the fertile fronds of L. capiUacea. 



(5) L. Merrilli Copeland. Rhizome stout, scandent, shining, sparsely 

 clothed with spreading ferruginous paleae; stipe 2 to 5 cm. high, stout, 

 slightly scaly, at the top, straw-color, like the rachis; frond about 80 cm. 

 long, 4 cm. wide, pinnate; lower pinnae stalked, the larger ones 22 mm. 

 wide by !) mm. deep next the rachis, dimidiate, the base strongly drawn 

 down, making the pinnae deepest there, apex usually acute, lower margin 

 entire, upper inciso-crenate; glabrous, membranaceous; veins free; .sori 

 wider than deep, the acute tips of the lobes projecting over them.
