(1) L. repens (Desv.) Christ (DavaUia Desv., H. and B.). Rhizome 

 wide-creeping, paleaceous, climbing; frond simply pinnate, 20 to 45 cm. 

 long, 2 to 4 cm. wide; pinnae 1 cm. long, about half as broad as deep, 

 the lower line slightly curved, oblique at base, the upper rounded, nearly 

 entire or crenately lobed; texture pellucido-herbaceous ; sori marginal, 

 large, about as broad as deep, often confluent in the not crenate form. 



Luzon, Hdetike, Cuming 50; Mount Mariveles, 1,400 m., Loher 59; Davao, 

 Warburg 14109 and 14182. 



India and Mauritius across Polynesia. 

 Very variable in size. 



(2) L. hymenophylloides Blume. Rhizome scandent, 1 to 1.5 mm. 

 thick, paleaceous; frond sessile, simply pinnate, larger ones 20 cm. long, 

 2.5 cm. wide; pinnae 15 mm. long, 6 mm. deep, cut down to a winged costa 

 into linear-cuneate, entire or forked segments, each bearing 1, or rarely 2, 

 roundish sori ; texture membranaceous, entire frond glabrous. 



Mount Mariveles, Merrill 3220, Copeland 229, at 1,200 m. altitude. 

 Java and New Caledonia. 



Regarded by Hooker and Baker as probably a variety of L. repens. 

 Put by Diels into § Synaphlebium ; but our material has free veins. 



(3) L. scandens Hooker, Sp. Fil. I p. 205 t. 63 B. Rhizome stout, 

 wide-creeping, scandent, paleaceous; frond 20 to 30 cm. long, 4 cm. broad.
