 7 — 8 mm. broad, ± 1% em. apart; lower pinnae + 3cm. apart, opposite; 

 higher pinnae alternate; terminal pinna lanceolate-triangular, whether or 

 not lobed at the base. Texture subcoriaceous ; under surface and edges scaly 

 with black-purple, dilacerate or hair-like scales; rachis slender, provided

War„ hrevipes: Stipes short, 1 cm. long ; pinnae bluntish or acute. 



¥'ar. Mbd.usifoliuiu: Fronds shorter, to 20 cm. long by 2 cm. broad ;

Ehizome short-creeping, woody ; scales dense, lanceolate, shortly acum-

 rachis grey-green or purplish, naked. Fronds broadly linear, to + 20 cm. 

 long, 6 cm. broad, acuminate, pinnate. Pinnae + 20 on each side below 

 the serrate-lobate terminal one, alternate, suberect, petiolulate, lanceolate, 

 subfalcate, lobed, serrate towards the shortly acuminate apex, obUquely 

 cuneate at the base; lower pinnae + 6 cm. long, 1';, cm. broad, nar- 

 rowed gradually towards the apex. Lobes obtuse, sharply serrate with 2 

 or more teeth, the lowest anterior lobe auricle-like, nearly free. Texture 

 chartaceous to coriaceous; surfaces naked; costae and veins prominent; 

 veins once or twice forked, the lowest anterior pinnate in the auricle. 

 Sori long, slightly curved, reaching nearly from the costa to the margin, 

 those of the auricle sometimes apparently diplazioid; indusium firm.

A very variable species, with the pinnae not rarely much shorter 

 than in the type, whether or not auriculate on the upper side at the 

 base and the auricle sometimes free, cuneate-obovate.
