moderately thin (linear or subulate in transversal section), rounded or 

 acute at the edge, the costal parenchyma nearly as broad as the lamina 

 or produced a little beyond the margin. — V. minor Fee (V. Loheriana 

 V. A. V. U.) is a narrow form with the fronds + '/a as thick as broad 

 in the fertile region, and united with the type by intermediates between 

 which it is impossible to draw the precise limit. — A plant gathered in 

 Borneo by Hallier, determined as V. debilis Kuhn (Ann. Btz., XX, 129), 

 has the upper, surface provided with scattered, deciduous, stellate hairs. 



War. novog'tiiiiecnsls: Fronds very narrow, + 1 mm. broad 

 in the barren region, to twice as broad and very thick in the fertile region.

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

 Fronds sessile, crowded, ligulate, 5 — 10 cm. long, 3 — 4 mm. hxoAA, obtuse, 

 narrowed towards the base. Texture coriaceous ; midrib visible in the 

 lower part, lost in the fertile region; veins forked, or rarely sub- 

 pinnate. Sori confined to the upper half of the frond, the lamina beyond 

 the sori rather thick, the margin 2-angied (obliquely truncate in transversal 

 section), the costal parenchyma + half as broad as the lamina.
