Rhizome sliort-creeping, tlie scales small, linear-subulate, brown. Stipes 

 subapproximate, + 10 — 15 cm. long, naked, winged in the upper part. 

 Fronds + 15 — 18 cm. long, irregularly 8 — 4-pinnate at the base, the 

 rachises winged, the wings 3 — 5 mm. broad, passing gradually into the 

 ultimate segments. Pinnae erecto-patent, alternate, 3 — 5 on a side, the 

 higher simple, the lower to 14 cm. long, irregularly decompound, with 

 the various divisions erecto-patent, alternate; ultimate segments linear- 

 subulate, ± Vi — ^ f'™- long) 1 — 2 mm. broad at the base. Texture 

 chartaceous ; central ribs of the segments prominent beneath ; veins oblique, 

 simple or rarely forked ; surfaces naked. Sori minute, occupying the ultimate 

 segments, placed in single rows medial between the midrib and margin.

Rhizome short, erect, hidden by the roots and stipes. Stipes tufted, 

 + 2 — 3 cm. long, wiry, densely clothed with long, spreading, ferrugineous 

 or pale-coloured hairs, at length naked like the rachis. Fronds lanceolate, 

 + 15 — 25 cm. long, 272 — 5 cm. broad, narrowed towards both ends, the 

 apex coarsely and remotely toothed. Pinnae erecto-patent or spreading, 

 stalked, straight or often decurved, sometimes linear and coarsely sub- 

 remotely toothed, more commonly lanceolate and regularly pinnate, the 

 largest to 3 cm. long, to 1 cm. broad near the base, subcaudate-acuminate 

 and coarsely toothed at the apex. Pinnulae linear, ± 1^4 mm. broad, 

 coarsely toothed. Ultimate segments (teeth) short, oblique, blunt or 

 rounded, 1 — 3 on each side of the pinnulae but more numerous in the 

 apices of the fronds and pinnae. Texture rigidly coriaceous; surfaces 

 naked; veins hidden. Sori roundish, solitary at the base of the teeth. 



Var. augustatiiin: Pinnae not caudate-acuminate, with the 

 divisions narrower, narrowly toothed.
