extremity simply pinnate, with a slightly prolonged pinnatifid point; 

 inferior 3 or 4 pairs of pinna? sessile, ascending, pinnate at the base, 

 while towards the point they are decurrent and deeply pinnatifid, 

 with a bluntly serrated point : pinnules from one to 2 inches in 

 length and 4 to 5 lines broad, lance-oblong, subfalcate, incisely-lobed 

 or obtusely and deeply serrate ; the lobes semi-oblong, incurved, and 

 crenate. RhacMs (main and secondary) beset with scattered, slender, 

 reticulated paleos on the under side, the upper with a short brown 

 pubescence. Sori solitary, and arranged in an irregular line near the 

 margin of the pinnules, seated close to the base of the sinus of the 

 lobes. Indusium large, round-reniforrn, entire, with a deep sinus at 

 the point of attachment.

Stipe a little over a foot in length, about the thickness of a goose- 

 quill, slightly compressd, sulcate in front, shaggy with the long and 

 slender brown palew, which almost conceal its surface. Fronds mem- 

 branaceous, about 2 feet long, ovate and acuminate in outline, of a 

 paler colour on the under than upper surface, bipinnate at the base, 

 towards the point decreasing gradually in the number and deepness 

 of its divisions, and terminating in a deeply pinnatifid point : pinnules 

 from one to li inches long, oblong-lanceolate or lanceolate, subfalcate, 

 with a very slight inclination to a trapezoidal form ; the inferior ones 

 someichat petiolate and deeply pinnatifid; the superior sessile, bluntly 

 serrate, both strigose with short appressed hairs, but most so on the 

 upper surface. Rhachis (primary and secondary) together with the 

 costa of the pinnules, furnished with scattered palea, appressed to the 

 surface. Veins dichotomous. Sori punctiform, scattered and distant, 

 with a small, lacerated, fugacious, round-reniform indusium,
