1 84 Ferns of British India and Ceylon. 



Fil. 236 (in part). Diplazium Stoliczkae, Clarke, F. N. I. p. 500. 

 Diplazium thelypteroides, Bedd. F. B. 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 1 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. 

 Bl. En. 195. Diplaz. polypodioides, Hook. Syn. Fil. 238 {in part). 

 Diplaz. polypodioides, Bedd. F. S. I. t. 163. Diplaz. sikkimense, 

 Clarke, F. N. I. p. 500, t. 6$,Jig.z, 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, 1 inch 

 long ; stipes densely tufted, stout, green, 1 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
