Diplazium thelypteroides, Bedd. F. Bi I. t. 68. 
Himalayas; Nepal to Bhotan, 7,000-10,000 feet very abundant 
about Darjeeling. This and the type may run into each other, but as 
yet only one specimen of the type is known ; they both look very 
different to the Malay sorzogonense, and differ by the lobes being 
more serrated, the veinlets being often forked, the sori never reach- 
ing the margin and being confined to the 3-4 lower veinlets. 
16. Diplazium asperum. {Bl) Caudex erect, often quite a 
large trunk, (like Alsophila) stipes main and partial rachises prickly 
and scaly ; fronds large^ rather coriaceous, bipinnate with the pin- 
nules pinnatifid nearly to the rachis, pinnules quite at right angles 
with the rachis, sessile or subsessile, 3-5 inches long, about i inch 
broad, segments very regular, forming an oblong parallelogram, or 
slightly falcate, obtuse, crenate, or serrate, often rather sharply ; 
veinlets numerous, 8-12 in each segment, generally simple, rarely 
forked, all or nearly all generally soriferous ; sori touching the costa 
but not the margin, generally only one of the lower ones double.

Diplaz. polypodioides, Bedd. F. S. I. t. 163. Diplaz. sikkimense, 
Clarke, F. N. I. p. 500, /. 6^,Jig.i, scarcely differs, and is certainly 
nearer to this than polypodioides. 
Madras Presidency ; throughout the Western forests, from no 
elevation up to 3,000 feet, often quite a tree fern ; Cuddapa forests ; 
Sikkim, banks of the Teesta, 500 feet. 
(Also in Java.) 
17. Diplazium polypodioides. {Mett.) Caudex erect, stout, 
densely clothed at the crown with long brown fibrillose scales, i inch 
long; stipes densely tufted, stout, green, i foot or more long; 
fronds 3-4 feet long, and 2 feet wide, bipinnate, with 8-9 primary 
pinnae on each side below the simple ones, the lower ones generally 
distant, secondary pinnae 2-4 inches long, cut down nearly to the 
rachis in the typical form, but sometimes only down ; segments 
short oblong, crenate or serrate, or subentire; veinlets about six, 
generally forked, sometimes simple ; texture herbaceous ; surfaces
