 but scarcely imbricate; texture pellucido-herbaceous ; sori in a continuous 

 or slightly interrupted line along the upper edge.

Baker says this is merely a variety of L. cultrata. 



(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-membrana- 

 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, pinnae stalked; texture 

 coriaceo-membranaceous.

Madagascar and Himalayas to Queensland and perhaps Japan. 



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

 shorter frond and stipe, membranous texture, and very variable form of 

 the pinnae.

(11) L. adiantoides J. Sm. (L. humilis Kuhn). Stipes nearly tufted, 

 black, polished, wiry, 2 to 5 cm. high; frond 10 to 15 cm. long, about 

 2 cm. broad, simply pinnate; pinnae 1 cm. long, 6 mm. deep, the upper 

 imbricate, the lower edge straight or slightly curved, the upper rounded 

 and broadly lobed about one-third of the way down; texture pellucido- 

 herbaceous; sori marginal in the lobes.

(12) L. loheriana Christ, Bull. Herb. Bois. 6(1898) :144. Rhizome 

 short-creeping, firm; stipes 2 cm. long, fasciculate, terete, slender but 

 firm and erect, base purple; frond 12 cm. long, 1 cm. wide, lanceolate- 

 acuminate, simply pinnate; pinnae alternate on 2 mm. long petioles, 5 mm. 

 long, triangular-cuneate, lower edge entire, upper deeply bifid; lobes 

 broadly cuneate, with evident, forked, free veins; sori terminal, single
