 15-30 cm long, 2-4 J cm broad, evergreen ; rachis slender, stramineous when 

 dried, hard, rounded at the back, canaliculate in front, thinly dispersed 

 with light leather-coloured thinly membranaceous caudato-acuminate ir- 

 regularly eroso-dentate triangular small scales ; pinna? numerous, 22-44 on 

 each side, approximate, basal ones slightly distant, opposite or nearly so, 

 regularly arranged, horizontally patent, or a little reflexed, dimidiate, sub- 

 trapezoidal-oblong, with an ovato-deltoid acute-tipped and obsoletely crenato- 

 margined auricle in upper lower base which is in its inner side parallel to 

 the rachis, very shortly petioled, or subsessile, obtuse with a sharply acute 

 tip at the apex, obliquely and broadly cuneate at the base, crenato-serrate 

 or serrate with simple or sometimes duplicate mucronate teeth entirely in 

 the upper and merely the lower superior margins, subcoriaceous, naked, slightly 

 glossy, pallid-green, the largest one 2J cm long, 1 cm broad ; veins nearly 

 straight, flexuous above, pinnate, with a branch running from the base to the 

 auricle ; veinlets erect-patent, loose, all free, mostly bifurcate, but those in the 

 auricle mostly simple. Sori intramarginal, in 2 rows on the pinna and often 

 the auricle, terminal on veinlets, distinct, prominent, approximate ; indusium 

 orbicular, peltate, irregularly eroso-dentate on the margin, thinly membrana-
