64 POLYPODIACE^ OF THE PHILIPriNE ISLANDS. 



or forked segments to a recurved filiform rachis; sori small, nearly terminal 

 on the dilated apices of the segments; involucre suborbicular. Epiphytic.

(18) L. Sarasinorum Christ, Ann. Bot. Buitenzorg. 15:101. Rhizome 

 short-creeping; stipe 12 cm. high, reddish brown, clustered, brown-squa- 

 niulose, as is the rachis; the rest of the plant glabrous, herbaceous in 

 texture; frond 8 to 12 cm. long, simply pinnate or tripartite; pinnse 

 (pinnules) halved at the base, becoming equilateral toward the apex; 

 narrowly oval or rhomboidal, up to 3 cm. long, strongly bent outward, 

 on the outside lobed into 4 or 5 lobes, which are often forked, broad, obtuse, 

 with a thick, brown, apical sorus; veins freely anastomosing near the base, 

 free toward the margin. 



Maquiling, Loher. 



Celebes. 



Differs from L. davallioides in that the pinnae are longer, narrower, 

 arcuate-deflexed, and not dimidiate at the apex, and the lobes broader, 

 deeper, and often forked. 



(19) L. davallioides Blume. Rhizome short-creeping; stipe 6 to 12 

 cm. high, firm, erect; frond with a long central point and one to three 

 pairs of spreading curved branches. 4 to 8 cm. long; pinnae 1 cm. long, 



5 mm. broad, the lower margin straight or slightly curved, the upper with 

 3 to 6 regular trimcate lobes one-third the depth of the pinnae, placed close 

 together but not imbricated; texture pellucido-herbaceoiis; veins anastomos- 

 ing below the base of the lobes; sori marginal in the lobes. 



Castillo, 800 m., Loher .53; Daet and Gubat, Baramla 16; Mount Mari- 

 veles, Copeland 1380. 

 Malay region. 



(20) L. lobata Poir. Rliizome short-creeping; stipe 10 to 20 cm. high, 

 firm, erect; frond simply pinnate or with a long unbranched apex, and 1 to 



6 pairs of erecto-patent branches, 7 to 20 cm. long; pinnules 10 to 13 cm. 

 long, half as broad, the lower decurved principally at the base, the outer 

 margin rounded, the upper entire or incised enough to interrupt the 

 sorus, close-placed, but not imbricated; texture thinly pellucido-herbaceous; 

 veins anastomosing; sori marginal. 



Luzon, Steere ; Paragua, Merrill 713. 

 India to Polynesia and Queensland. 



Much resembling L. davallioides in general appearance, but the pinnules 

 are deeper and not so much lobed. 



(21) L. apoensis Copeland. Rhizome 1 mm. thick, scandent, ferru- 

 ginous, almost glabrous; stipes 12 to 18 cm. high, straight or flexuous, 

 stovit, the bottom rich brown, upward green and nearly glabrous, as is 

 the rachis: frond about 20 cm. high, 6 cm. broad, pinnate; pinnae short- 

 stalked, glabrous, herbaceous, the larger ones 40 by 7 mm., the lower 

 margin arcuate, the upper incised into usually linear lobes, more deeply 

 toward the end of the pinna; veins free except sometimes in the sori; 

 sori small, roundish, just below the tip of the lobe.
