Stipes slender, 2 to 3 inches long, about the thickness of a sparrow's 

 quill, smooth and naked, half round. Fronds 8 to 12 inches long, 

 linear-lanceolate, bipinnate, rarely tripinnate, with a scaly bulb on the 

 rhachis between the two inferior pinnae. Pinnce on a short petiole, 

 imbricated, in outline deltoid-ovate. Pinnules from 3 to 5 in number, 

 smooth, cuneate, and sessile, about 3 or 4 lines long, the terminal one 

 the largest, entire, bi—tridentate. Veins simple or bi-trichotomous. 

 Son oblong, solitary, seldom 2 on a pinnule. Indusium membranceous, 

 entire, and of a straw-colour. 



There is no doubt of our plant being identical with that figured in 

 the Icones Filicum, notwithstanding that the authors of the species 

 did not notice the scaly bulb on the rhachis, between the inferior pair 

 of pinnae ; an appendage, that by accident, or some other cause, might 

 not have been present on their specimens, but which is very evident 

 on all of ours.

There is only one perfect specimen of this rather elegant Fern in 

 the collection ; and this is somewhat larger than the plant described 

 by Kaulfuss.
