58 POLYPODIACE^E OF THE PHILIPPINE ISLANDS. 



glabrous; veins subflabellate ; sori at base of ultimate sinuses; receptacle 

 cup-shaped, glabrous. 



Luzon, Cuming 231 ; Mount Arayat, Loher. 



Batjan. 



(3) D. scabra (Wall.) Moore. Rhizome wide-creeping; stipe 30 cm. 

 high, scabrous; frond 25 to 80 cm. high, deltoid or lanceolate, bipinnate; 

 pinnae lanceolate; pinnules quite distinct, the lower ones cut down nearly 

 to the rachis into numerous pinnatifid oblong deltoid segments, herbaceous 

 or subcoriaceous ; rachis and both surfaces more or less hairy ; sori 2 to G 

 to the lower segments; receptacles cup-shaped, subglobose. 



Baguio, Loher. 



India to Celebes and Japan. 



(4) D. scandens (Bl.) Moore. Rhizome scandent; fronds sometimes 

 several meters long, growing indefinitely at the apex, climbing by means 

 of their prickly rachises, tripinnate, with the segments bearing broad 

 teeth, flaccid; sori small, placed in the sinuses. 



Davao, Warburg 14160. 

 Malaya and Polynesia. 



(20) MONACHOSORUM Kuntze. 



Rhizome short; stipes therefore clustered, not articulate to the rhizome; 

 frond large, finely dissected; sori a little below the tips of the veins, 

 indusium wanting. The Philippine species is a fairly large terrestrial 

 fern, of very doubtful affinity. 



(1) M. subdigitatum (Bl.) Kuhn. Stipes tufted, firm, 20 to 50 cm. 

 high, stramineous, glabrescent; frond 45 to 60 cm. high, hardly as broad, 

 quadripinnate; pinnae horizontal, the lowest 20 to 30 cm. long, 10 to 15 

 cm. broad; pinnules lanceolate, their segments cut down in turn to their 

 rachis into divisions which in the lowest part of the frond are deeply 

 bifid, pellucido-herbaceous, dark green, turning back in drying, glabrous; 

 vein one in each ultimate segment, not reaching the margin; each vein 

 bearing one sorus below its apex. 



Davao, Warburg 14178, DeVore and Hoover 323, Copeland 1032, 1143. 



India, Malaya. 



(21) SCHIZOLOMA Gaudichaud. 



Fronds in the Philippine species tufted, pinnate ; pinnae not dimidiate ; 

 veins free; sori forming a continuous submarginal line, protected by the 

 more or less inflexed margin and the continuous extrorse indusium. Our 

 first species, not hitherto known from the Philippines, has the 'aspect 

 of an Asplenium, and in its fructification is strikingly like Vittaria, to 

 which genus it was first referred; its nearest relatives are probably in 

 Lindsaya. 



(1) S. divergens (Wall.) Diels. Stipes erect, about 10 cm. high, 

 black, polished; frond 15 to 30 cm. high, 3 to 4 cm. broad; pinnae close, 

 horizontal, except the lower ones which are strongly deflexed and much 

 reduced, lanceolate, obtuse, entire, obliquely truncate on the lower side
