 lobum & microlobum, Rst., 1. c, 170. 



Stipes firm, 20 cm. or more long, like the rachises and costae black- 

 brown and naked. Fronds ovate or deltoid-lanceolate, sub-3-pinnate, + 

 36 cm. long by 26 cm. broad, acuminate. Pinnae + 12 on a side below 

 the pinnatifld apes, horizontal on the lower deflexed, petiolate, lanceolate- 

 oblong, the central the largest, + 16 cm. long by 6 cm. broad, acuminate. 

 Pinnulae + 12 on a side below the serrate-dentate apex, ascending, 

 petiolate, lanceolate-oblong, the lowest the largest, + 3'/2 cm. long by 1 

 cm. broad, bluntish, very deeply pinnatifld. Lobes + 8 on a side below 

 the serrate apex, upcurved at the apex, ■ recurved and serrate or dentate 

 at the edge, the higher and medial decurrent, the lower connected by a

Forms recently gathered by different collectors have the pinnulae 

 cut down nearly to the costa, the texture very thin, the sori sparse, the 

 veins pinnate in the lobes, the lowest veinlets simple or forked, sterile, 

 or occasionally fertile and the lowest sori then usually double, the under 

 surface often minutely scaly on the costae.
