•the hairs redrbrown or pale-ochraceous, often decurved. Fronds lanceolate, 

 15 — 45 cm. long. 5 — 10 cm. broad, acuminate; rachis and costae densely 

 short-hispido-pubescent above, deciduously long-hispido-setose beneath, the 

 hairs pale. Pinnae deciduously hispido-ciliate ; terminal pinna triangular- 

 lanceolate, broadest at the deeply pinnatifid and broadly cuneate base, 

 entire or crenate at the long-caudate-acuminate apex ; lateral pinnae 

 remote, much ascending or the lower more spreading, 10 — 20 on a side; 

 Irigher pinnae linear-oblong, adnate, entire or subentire; central pinnae 

 largest, linear-lanceolate, 3—6 cm. long 4—6 mm. broad at the middle, 

 entire at the long-acute point, cut ' ^-way down to the costa towards the 

 subabruptly .cuneate base; inframedial pinnae more or less gradually 

 abbreviated and often somewhat more deeply incised; lower pinnae 

 suddenly rudimentary. Lobes obliquely sub triangular, blunt or bluntish, 

 entire or subentire. Texture firm-herbaceous; surfaces naked or the 

 .under one provided with scattered, minute, yellow, subglobose glands ; veins 

 3 — 5 on a side, the lowest uniting at or a little below the sinus. Sori 

 medial or supramedial on the veins; indusium firm, naked, persistent, 

 dark-brown when dry.

Stipes + 15 — 20 em. long, fuscous or brown, scaly and black at the 

 base, narrowly grooved down the face, clothed with minute, adpressed 

 "bristles. Fronds lanceolate, + 35 — 45 cm. long, + 10—15 cm. broad, 

 ■pinnate, the rachis tomentose with minute, adpressed bristles, as are the 

 costae. Pinnae + 15 — 25 on each side below the terminal one; lateral 

 pinnae alternate, the central ones the largest, linear-lanceolate, + 6^8 

 cm. long, + 7 — 9 mm. broad, ascending, remote, short-stalked, caudate- 

 acuminate, serrate-crenate, unequal-sided at the base, the upper base 

 rather broadly cuneate, parallel to the rachis and often slightly auriculate, 

 the lower narrowly cuneate, the caudiform apex rather entire; lower 

 pinnae gradually more or less reduced; terminal pinna lobed towards the 

 base. Texture firm-herbaceous or membranaceous; surfaces naked but 

 ■'the edges and veins beneath sparingly cihated; veins 2 — 3 on each side 

 of the main veins, the 2 lower anastomosing. Sori in 2 — 3 rows on 

 each side of the costa, the lowest often contiguous or confiuent (as in
