404 Ferns of British India and Ceylon. 



elevation, not very common ; Ceylon, central provinces ; Himalayas 

 and Khasya up to 5,000 feet ; Malay Peninsula. 



(Also in the Malay Islands, Philippines and Polynesian Islands.) 



3. Antrophyum tatifolium. (Bl.) Stipe long up to 7 inches; 

 fronds large, broadly obovate or round, up to 4f inches wide, acuminate 

 or acutely lobed at the apex, no midrib ; sori superficial or immersed, 

 with the frond plicate above. Bl. Fl. Jav. Fil. 75. Bedd. F. B. I. 

 t. 176. 



Sikkim and Bhotan, 2,000-6,000 feet ; Assam and Khasya 

 1,000-4,000 feet elevation. 



(Also in Java.) 



Supposed to differ from the last by the sori being supeificial; 

 they however are deeply immersed in some of my specimens, so it 

 only differs in its much broader frond and longer stipes ; all the three 

 so-called species are probably only varieties of one plant. 



GENUS LXXVIL— VITTARIA. (Sm.) 



( Vitta, a riband, the riband-like frond.) 



Veins simple, forming an acute angle with the midrib, their 

 apices prolonged into a transverse marginal vein, which becomes the 

 receptacle, or veins forked without the transverse marginal vein ; sori 

 seated in an extrorse groove of the margin, or in a slightly intra- 

 marginal line with the unaltered edge of the frond produced beyond 

 and often rolled over it ; fronds adherent to the caudex, linear, grass- 

 or tape-like. 



1 . Vittaria elongata. (Sw.) Rhizome creeping, scales many, 

 with black hair-like points ; fronds up to 2\ feet long, generally only 

 \ inch broad, acuminate, grass-like, but rather firm in texture, mid- 

 rib generally more or less distinct beneath ; veins simple, oblique, 

 immersed, parallel, connected by an intramarginal veinlet ; sori quite 

 sunk in an extrorse marginal groove. Sw. Syn. Fil. 109, 302. Wall.
