Martaban. This seems as distinct a species as most of this group,

5. ViTTARiA LiNEATA. {Sw) Rhizome very short creeping; 
stipes tufted, scales acuminate with caudate points ; fronds up to 8 
inches long, -|— |- inch broad, narrowed gradually downwards to the 
stout compressed stipe, the margin often reflexed, texture thick, a 
distinct raised midrib from the base to the apex ; veins simple, im- 
mersed, parallel, very oblique ; sori in a broad intramarginal shallow 
furrow, the edge of the frond distinctly beyond the furrow and at first 
wrapped over it. Sw. Syn. FiL p. 109. FLook. Syn. FiL 396. Tseni-
