the base to the apex, slightly sulcate above; veins subimmersed, oblique, simple, 

 free, the apices not or haHly thickened, hardly produced beyond the recep- 

 tacle in the fertile region. Sori in rather deep grooves betvsreen the thickened 

 costal parenchyma and the margin; the margin ± thin, much produced beyond 

 the costal parenchyma, which is + half as broad as' the lamina, i. e. the 

 leaf-tissue beyond the soral groove in transversal section ± as in V. pusilla, 

 BL, but rather spreading.

Rhizome ascending, the scales membranaceous, yellow-brown, lanceolate, 

 not acuminate. Fronds multiseriate, 2 — 12 c.M. long, + 3 — 4 m.M. broad 

 and nearly as thick, simple or occasionally forked, straight or falcate, linear- 

 ligulate, the apex blunt or rounded, the lower part narrowed gradually to the 

 base. Texture coriaceous, firm; midrib + distinct beneath, but lost in the 

 not abruptly thickened fertile region, slightly sulcate above ; veins free, oblique, 

 forked, transversed by the receptacle in the fertile part. Sori confined to the 

 upper V3 — % of the frond, deeply sunk in submarginal grooves, the thickened 

 costal parenchyma nearly as broad as the lamina or produced a little beyond 

 the margin, which is rather thin, i. e. the leaf-tissue beyond the soral groove 

 in transversal section rather narrowly linear with the base ± as broad as 

 the extremity or the latter narrowed.

Rhizome short-creeping, the scales dense, pale-brown, lanceolate. Fronds 

 crowded, ligulate, obtuse, sessile, narrowed towards the base, 5 — 10 c.M. long, 

 3 — 4 m.M. broad. Texture coriaceous ; midrib visible in the lower, barren part 

 of the frond, quite lost in the thickened, fertile region; veins forked or rarely 

 with 2 branches, not reaching the margin. Sori in deep, intramarginal furrows, 

 occupying the upper half of the frond. The margin very thick, much
