deflexed. Pinnulae + 1^/^ c.M. broad, serrato-caudate, cut down nearly to

Fronds 3-pinnatifid, the rachis livid- fuscous, unarmed, strigose above, 

 clothed beneath with linear-lanceolate, ferrugineous, copiously and irregularly 

 dilacerate, spinuloso-ciliate scales. Pinnae to 40 c.M. long or longer, to 20 

 c.M. broad, short-stalked, the petiole articulate to the main rachis, the rachis 

 hirsute and scaly like the main one. Pinnulae 12 — 15 on each side, sessile, 

 linear, narrowly acuminate, deeply pinnatifid, to 10 cM. long, + 2 c.M. 

 broad, slightly narrowed at the base, the terminal one lobed, serrate at the 

 apex. Lobes broadly linear, obtuse, entire, subfalcate, remote. Texture char- 

 taceous; surfaces livid-green, glossy, nearly naked; costae and costulae scaly 

 like the rachises, the scales copiously intermixed with while, acuminate, bullate 

 .squamulae; veins 4 on each side of the costulae, forked, conspicuous, brown. 

 Sori ± medial between the costulae and the margin, + 7 — 8 to each lobe,

Stipes rather thick, 15 — 20 c.M. long, the base black, densely clothed 

 with subulate-setaceous, flexuose, lucent, black-brown scales, the rest rufo- 

 castaneous and rough with minute verrucae, as is the rachis. Fronds 3-pinnate, 

 to 1 M. or more long, ± 25 c.M. broad, ovate, acuminate, narrowed gradu- 

 ally towards the base. Pinnae distant, ± 10 — 15 on each side, erecto-patent, 

 medial largest, sessile, + 55 c.M. long, ± 14 c.M. broad, caudato-acuminate, 

 not narrowed at the base. Pinnulae subremote, ± 1 '/2 c.M. apart, sessile, 

 ± 20 on each side, cut down to the costa (rachis). Tertiary segments ap-
