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.

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.) 
( Viita^ 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. 
I . ViTTARiA ELONGATA. {Sw.) Rhizomc Creeping, scales many, 
with black hair-like points ; fronds up to 2^ feet long, generally only 
i inch broarl, 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. Szu. Syn. Fil. 109, 302. Wall.
