terminal one. Pinnae sessile or short-stalked, more or less close or the larg- 

 est ones distant, the barren ones the largest, 1 ^j^ —5 c.M. broad, the apex 

 acute or short-acuminate, the margin entire or slightly lobed, the base ± 

 truncate, not rarely ± auricled above; fertile pinnae generally considerably 

 contracted, but sometimes the larger uncontracted pinnae sonferous. Texture 

 papyraceo-herbaceous ; surfaces + short-hairy, the under one glandular with 

 numerous, dot-like, yellowish glands ; veins to 12 pairs in the larger pinnae, 

 4 — 8 in the narrower ones, nearly all anastomosing except the highest ones. 

 Sori medial on the veins, eventually elongating, meeting, and covering the 

 whole of the veins so as to become meniscioid; indusium fugacious, ciliate.

Rhizome short-creeping or erect, clothed with small, ovate-lanceolate 

 scales at the extremity. Stipes approximate, 20 — 60 c.M. long, naked or 

 short-hairy, stout, erect. Fronds ± 45 — 120 c.M. long, 25—45 c.M. broad, 

 with a terminal pinna and below this 2 — 7 lateral ones on each side. Pinnae

 narrowed, the edge entire, crenate, serrate or sharply toothed, the apex acumi-
