 at the top; stipe 30 cm. or more high, dark brown at the base, lighter 

 above and glabrous; frond 50 to 100 cm. high, half as broad, apex pin- 

 natifid into deep, repand or lobed segments; below this numerous distinct 

 pinnae, the lowest 15 to 20 cm. long, lanceolate-deltoid, lobed throughout 

 into broadlj' lanceolate lobes of which all except the lowest basipetal one 

 are entire or nearly so, subcoriaceous, glabrous; areolae copious, with

 high, with a few small, lanceolate scales at the base, fibrillose near the 

 top, like the rachis; frond 15 to 25 cm. high, deltoid, usually trifoliate, 

 with a deeply tripartite apical segment, less often with the apical 

 segment entire, or with an extra pair of entire pinnae intercalated; lowest 

 pinnae short-stalked, about 10 cm. long, furcate with the smaller, lower

 veins; sori copious, irregularly scattered, round or elongate, exindusiate, 

 bright, deep red.

 falcate lobes reaching half way to the costa; lower pinnae often deltoid,

 glabrous; areolae copious with few free veinlets; sori very copious, 

 scattered.

 veins conspicuous on the upper surface; ape.x pinnatifid, tlic segments 

 broadly crenate and obscurely serrate ; below this about free pinnae on 

 each side, erecto-patent, acuminate, lanceolate, pinnatifid more or less 

 than half way to the rachis into oblong, obtuse, entire or serrate lobes, 

 lower pinnae stalked; lowest ones deltoid, with one free basiscopic piniiiili^
