reddish linear-lanceolate scales at the base ; fronds up to 3 feet, 

 oblong-lanceolate, generally 2-pinnate, or in some forms only pinnate ; 

 slightly narrowed, never attenuated at the base, coriaceous, rigid, 

 somewhat shining, striated when dry ; primary pinnae often falcate, 

 sometimes only pinnatifid half-way to the rachis, i|-2 inches long, 

 generally much larger ; 2-4! inches long, and pinnate, the pinnules

The exinvolucrate variety, called 

 Kulhaitense by Clarke, is eberneum. 

 (Wall.) It only differs in the absence 

 of the involucre ; the i-pinnate 

 form with short pinna; looks different 

 at first sight, but gradually runs 

 into the larger and more compound 

 forms. 



Himalayas, from Gurwhal to 

 Bhotan, 4,000-11,000 feet; Khasya 

 3,000-11,000 feet. I do not feel 

 certain that the Khasya specimen 

 called stramineum J. Sm. really be- 

 longs here, though it is so sorted in 

 the Kew bundles ; it is very like 

 some of the Nilgiris forms of Athy- 

 rium selenopteris. 



12. Athvrium drevisorum. (Wall.) Stipes 1 \ foot and more 

 long stramineous-brown below, glossy ; fronds 1^-2 feet long, ovate- 

 lanceolate, membranaceous, bi-tripinnate ; primary pinnce long-petio- 

 late remote erect-patent, a foot and more long, broad-lanceolate, 

 acuminate ; secondary pinnae 5-6 inches long, lanceolate, nearly 

 sessile, pinnated; pinnules numerous, approximate, oblong-lanceolate, 

 much acuminate, horizontally patent, 1— 1 i inch long, coarsely 

 serrated, rarely subpinnatifid, the serratures very acute, almost
