the base), reddish- or purplish-browii, ferru^ineo-furfuraceous, asperous by 

 innumerable mituite, conical élévations and sparingly scaly, as are the main 

 and secondary rhachises; scales of the stipe rather long, lanceolate, pale- 

 or yellow-brown, very long-acuminate, with the margin darker, wheii young 

 copiously fimbriate, at length erose; of the secondary rhachises miich smaller, 

 narrovver. Fronds to + 2'/2 m- long including the stipe, deeply 3-pinnati- 

 partite, sub-3-pinnate; main rhachis provided beneath with 2 opposite rows 

 of rather small, somewhat elevated, truncate-conoid tubercles (aërophores), 

 especially belovv or bctweeii the bases of the lower pinnae besides 1—3 

 somewhat larger tubercles at the bases of the pinnae. Pinnae elongate- 

 lanceolate, acuminate; largest pinnae subsessile, to + 50 cm. long and 18 cm. 

 broad, with the rhachis above hirsute with somewhat crisped, ferrugineous 

 or castaneous hairs, beneath provided with small, solitary. conoid tubercles 

 at the bases of the pinnulae ; reduced lower pinnae (if présent) proportionally 

 long-stalked. Pinnulae coriaceous, rather rigid, naked, dark above, paler 

 beneath, the largest horizontal, sessile, lanceolate-triangular, to 8— Q cm. 

 long, to 2 — 2'/2 cm. broad at the base, deeply pinnatipartite at the middic, 

 deeply pinnatifid in the upper part, gradually serrate-crenate at the acuminate 

 apex, pinnate at or towards the base; costa above hirsute, beneath deci- 

 duously ferrugineo-furfuraceous and -squamulose, the scales flat, lanceolate, 

 erose or somewhat fimbriate-ciliolate. Segments nearly close linear-oblong, 

 mostly somewhat falcate, blunt to subacute, the higher minutely serrulate- 

 crenulate, the central and lower more distinctiy and irregularly serrate-crenate 

 at the middie, the lower free, adnate or the lowest subpetiolulate, truncate 

 at the base, horizontal; largest segments to l'/j cm. long, 3 mm. broad; 

 costula above naked, beneath chaffy, especially between the sori ; veins 

 to 10—12 on a side, mostly forked, sometimes twice forked, the higher 

 simple. Sori costular, to 5—7 on a side, not occupying the higher veins. 

 the lowest close to the costa; indusium pale-brown, cupuliform, the mouth 

 somewhat constricted, at length breaking down into 2—4 persistent lobes 

 or fragments.
