Rhizome creeping. Stipes close, + 20 cm. long, minutely puberulous. 

 Fronds + 20 — 30 cm. long, 4 — 5 cm. broad. Pinnae sessile, obtuse or 

 rounded at the apex, subauriculate and truncate at the base, the edge

Rhizome erect, the scales narrow, castaneous. Stipes + 30 cm. 

 long, shortly hirsute. Fronds + 35 cm. long (esclud. the reduced pinnae), 

 12 — 15 cm. broad, acuminate. Pinnae rather numerous, + 20 or more 

 on a side, sessile, + 1 — I'/a cm. broad, acuminate, cut '1.,-wa.j down to 

 the costa ; lower pinnae reduced to mere auricles. Surfaces white-setulose, 

 setose on the costae and veins; veins simple, 6 — 9 on a side. Sori 

 medial on the veins; indusium persistent, setulose.

Rhizome short-creeping, woody, clothed with linear-lanceolate, 

 ferrugineous, hairy scales. Stipes stramineous, sulcate and slichtly hirsute 

 above, terete and nearly naked beneath, as is the rachis. Fronds 

 •elongate-oblong, + 1 — 1 '/^ nr. long, 50 cm. broad, shortly narrowed at 

 both ends, 2-pinnatifld. Pinnae numerous, erecto-patent, approximate, 

 sessile, the largest linear-lanceolate, + 35 cm, long, 2',., cm. broad, very 

 deeply pinnatifid, acuminate and serrate at the apex; lower pinnae 

 abbreviated, 1 — 2 lowest reduced, auricle-like; terminal pinna triangular, 

 pinnatifid at the base, serrate at the apex. Lobes very numerous, 

 horizontal, linear, the largest to + 12'l, mm. long, 2\ mm. broad, 

 subobtuse, entire and slightly hairy at the edge, dilated at the base, the 

 sinuses as broad as the lobes, rounded; lower lobes of lower pinnae 

 often abbreviated, of the lower side sometimes somewhat produced. 

 Texture thinly herbaceous; colour bright-green; upper surface glandular, 

 lower more densely so, the glands yellow, sessile; costae grooved and 

 hirsute above, glandular beneath; costulae prominent on both sides, 

 slightly hairy ; veins ■ + 20 pair, simple, sparingly hairy, the lowest 

 meeting in the sinuses. Sori subcostular, approximate, confluent; 

 indusium membranaceous, glandular at the edge.
