(9) L. montana Copeland. Rhizome very short-creeping; ferruginous- 

 scaly; stipes 1 to 3 cm. high, tufted, slender, flexuous, red brown below, 

 upward becoming straw color and almost glabrous, like the rachis; frond 

 3 to 6 cm. high, 1.5 cm. broad, pinnate; pinnae stalked, 9 mm. broad, 

 6 mm. deep, the lower ones very deflexed, their lower margin reflex-arcuate, 

 upper margin round, entire or incised, general shape semiorbicular, upper 

 pinnae smaller, ascendent, with acute bases; texture coriaceo-meinbrana- 

 ceous; veins free, flabellate; sori submarginal, usually continuous. 



Mount Mariveles, altitude, 1,100 m., Copeland 230, terrestrial. 

 Different from L. concinna in the much shorter fronds, and deflexed, 

 firmer, and much deeper pinnae. 



(10) L. cultrata Swartz, Syn. 119. Rhizome short-creeping; stipe 3 

 to 6 cm. long, wiry, flexuose, rich brown; frond about 20 cm. long, about 

 2 cm. broad, simply pinnate; largest pinnae 12 mm. long, 6 mm. deep, 

 not imbricate, the lower margin straight or slightly curved, usually upwards, 

 the upper edge slightly lobed, so that the continuity of the line of the 

 fructification is broken, sometimes nearly entire, pinnse stalked; texture 

 coriaceo-membranaceous.

L. cultrata Sw. var. varia Copeland. Differs from the type in the much

 the pinnie.
