In this species a great diversity occurs, both in the size and division 

 of the fronds; these vary from 5 to 15 inches in length, oblong, acute, 

 cordate at the base and pinnate, sometimes pinnatifid, towards the point 

 confluent and decurrent. Segments lance-oblong, with a lobate-sinuate 

 margin, which, with the costa and veins on the upper side, are fur- 

 nished with scattered short hairs. Sori scattered, numerous on the 

 small as well as on the larger fronds, and on some may be said to be 

 crowded and partially confluent. Indusium orbicular, with a slightly 

 undulated margin. 



This is certainly the Aspidium Hippocrepis of Swartz ; at least it 

 agrees with portions of the fronds figured under the name of Sagenia 

 Hippocrepis, by Presl and Hooker ; it is a plant of very frequent 

 occurrence in humid forests, at an elevation of from 2 to 8000 feet, 

 on various islands of the Sandwich Group.

The fronds of this are large and bipinnate, rising to a height of 3 

 to 5 feet, with stout, smooth, purplish-black stipes. The primary 

 pinnae are distant, subopposite and divaricate; the secondary ones 

 broadly lanceolate and pinnatifid; the segments membranaceous, 

 oblong-lanceolate, entire or sinuate-pinnatifid, with a slightly ciliate 

 margin, and puberulent on the upper surface. Sori few, small, sub- 

 serial, with an entire and orbicular indusium. 



We have no means of ascertaining satisfactorily that this is the S. 

 apiifolia of Mr. J. Smith ; but we are confident that it is the Aspi- 

 dium sinuatum of Gaudichaud, and also the Nephrodium apiifolium of 

 Hooker and Arnott, who have adopted Schkuhr's specific name with 

 a doubt, and which Gaudichaud, also with a doubt, employed as a 

 synonyme to his plant.
