Pinnae ± 9 c.M. long, ± 2 c.M. broad, sessile, elongate-oblong. Ihe 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 scales. 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.3I. broad. Pinnae sessile, linear-lanceolate, 2 — ^a'/j 

 c.M. broad, acuminate, the edge cut + ^s — Va^^^Y dovra to the costa into 



g oblong, rounded or subtruncate, subentire lobes ± Vj^ m.M. broad, the base 



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



"E. below this + 4 — 5 distant, much reduced, deflexed auricles, occupying the 



j§ 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 Ihe 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.
