 which are subterminal on the lobes.

(306) Wa. niti«la, Copeh, in Philipp. Journ., VF, 138, tab. XXI. 



Rhizome creeping, minutely scaly. Stipes rather approximate, + 30 

 cm. long, brown, quadrangular and deeply grooved, as is the rachis. 

 Fronds + 15 cm. long and 23 cm. broad, 2-pinnate, with 2 pairs of 

 opposite, sessile, acuminate branches below the terminal one. Leaflets 

 numerous, sessile, + IV4 cm. long and V2 cm. broad, entire or the 

 upper edge slightly and broadly incised, the outer edge rounded, and 

 bounded by a single intramarginal, narrow sorus. Texture papyraceous, 

 subdiaphanous; surfaces naked; upper surface glossy. — There is usually 

 but one sorus, rarely another small one in a lobe.

Fronds pinnate. Pinnae simple and to 3 cm. long, or 3-partite with 

 the pinnulae to 2 cm. long. Leaflets (pinnae or pinnulae) short-stalked, 

 obtuse rather than rounded at the apex, entire or the largest slightly 

 incised, broadest and abruptly truncate at the base. Sori long, almost 

 always without a break.

 largest leaflets to 2 cm. long, + 6 mm. broad at the base, the inner edge 

 parallel to the rachis, the upper and outer edge incised into + 7 truncate,
