We are satisfied that this is the A. salicifolium of Raddi, but doubt 

 its being that of Linnaeus. At least, the Lonchitis glabra major, t. 27, 

 of Plumier's PI. Amer. seems to be very distinct from that represented 

 by Raddi, who also quotes Plumier with a doubt, and by mistake cites 

 the wrong plate (17). 



10. Asplenium pavonicum, Sp. Nov. (Tab. 20.) 



A. ccespitosum; stipite nigro nitente semitereti parce muricato; frondibus 

 oblongo-linearibus pinnatis ; pinnis subsessilibus membranaceis oblongis 

 obtusis crenato-serratis basi in/erne truncato-cuneatis superne semi-au- 

 riculatis; rhachi apice prolifera ; indusiis lineari-oblongis integerrimis. 



Hab. Sandwich Islands : in shady, humid forests ; rare. 



Rootstock short and fibrous. Stipe half round, from 3 to 4 inches 

 long, black and shining, with two angles in front, and a few sparse, 

 short and hard, spinulose points on the surface. Fronds ccespitose, 8 to 

 10 inches in length, oblong-linear, in a young state attenuating towards 

 the point, truncate at the base, pinnate. Pinna? subsessile, membra- 

 naceous, crowded, from 8 to 10 lines long and 4 lines broad, oblong, 

 obtuse, the superior and outer inferior half crenate-serrate, the base 

 unequal, the superior half truncate and auriculate, inferior one cuneate 

 and entire, the lower one or two pairs of pinnae a little deflexed. 

 Rhachis proliferous at the apex. Sori from 6 to 9 on a pinna, with a 

 brown, plane, entire, linear-oblong indusium. 



From A. tenerum, this is distinguished by the black and spinulose 

 stipe, and the narrower fronds, rooting at the apex, with fewer and 

 shorter sori.
