Pinnae + 9 c.M. long, ± 2 c.M. broad, sessile, elongate-oblong the base 

 broadly truncate, narrowed gradually towards the acuminate apex, the margin 

 deeply pinnatifid; lower pinnae gradually reduced, obtuse, pinnatifid, the 

 lowest abortive, reaching nearly the base of the stipe. Lobes ovate-oblong, 

 subfalcate, obtuse, the lowest ones the largest. Texture rigid; upper surface 

 clothed with adpressed bristles, under surface covered with minute, sessile, 

 scattered glands: costae with a large tubercular gland beneath at the base ; veins 

 ± 8 on each side, the 1 — 2 lowest anastomosing. Sori + 8 on a side, medial 

 or nearer the margin than the midrib ; indusium subcoriaceous, naked.

Rhizome short, clothed with linear-lanceolate, brown, acuminate, hair- 

 covered sc;iles. Stipes approximate, ± 55 c.M. long, stout, erect, firm, green, 

 inconspicuously short-hairy, scaly towards the base. Fronds ovate-lanceolate, 

 + 50 c.M. long, + 30 c.M. broad. Pinnae sessile, linear-lanceolate, 2 — 2 '/a 

 c.M. broad, acuminate, the edge cut + ^s — ^li-^^J down to the costa into 

 oblong, rounded or subtruncate, subentire lobes + S^/^ m.M. broad, the base 

 truncate or subtruncate, the lowest not reduced pinnae the longest, deflexed; 

 below this ± 4 — 5 distant, much reduced, deflexed auricles, occupying the 

 upper half of the stipe. Texture ± coriaceous, rachis inconspicuously hairy ; 

 surfaces minutely hairy on the costae and costulae, rather naked; veins 8 — 10 

 on each side of the main veins, the 3 — 5 lower anastomosing. Sori numerous, 

 medial on I he veins, afterwards becoming subconfluent and densely covering 

 the under surface of the pinnae ; indusium reniform, with the surface covered 

 with very short hairs and yellow, globose glands. — The description is taken 

 from a specimen cultivated in the Buitenzorg gardens.
