side (inframarginal). Venules prominent on the upper surface. Son 

 small, biserial, in rather interrupted lines, and situated nearer the 

 costseform vein than the margin, furnished with a small reniform, 

 hairy indusium; the sessile sporangia bearing one or two clavate glands 

 on the side, near to the top.

Hab. Hawaii, Sandwich Islands : in dense forests. 



Fronds tufted, smooth on both sides, membranaceoiis and somewhat 

 flaccid, elongated-lanceolate, pinnate, with the point pinnatifid, usually 

 about 3 feet high, on a short and smooth, angular stipe, having a 

 single channel in front. Pinnce about an inch apart, sessile, opptosite 

 and horizontal, 4 to 6 inches long and 8 lines broad, linear, deeply 

 pinnatifid at the base, and tapering gradually into a repand-dentxxte 

 point, beset with numerous claret-coloured resinous globules on both 

 sides. Segments linear-oblong, obtuse towards the point, becoming 

 somewhat triangular-oblong, the inferior pair the largest, the margin 

 with crenules or blunt teeth. Costa on the upper side pubescent. Sori 

 of a golden hue, small, seated near the margin, and confined princi- 

 pally to the outer half of the segments. Indusium reniform, hirsute, 

 entire, but margined with a row of ?*esinous globules, which, when exa- 

 mined through a lens, present a very beautiful appearance. 



This is very distinct from the preceding species, nor do we know of 

 any one to which it is closely allied.
