Aspidium dilatatum, spinulosum, and dumetorum, Sm. E. 

 F. iv, 292, 3, 4, and also of Smith's Herbarium, now 

 in the possession of the Linnean Society. 



Aspidium spinulosum, Mack. Fl. Hih. 340 ; var. /3. Hook, 

 and Am. 671. 



Lastrea dilatata, Newm. N. A. 23 ; Bab. 411. 



Lastrea multiflora, Newm. F. 215. 



Lophodium multiflorum, Newm. Phytol. iv. 371. 



Rhizoma tufted ; stipes very stout, nearly as long as the 

 frond, densely clothed with long pointed scales, which are 

 dark brown along the middle but pale at the edges ; frond 

 glandular when young, very large, deep green, drooping, 

 ovate-lanceolate, j^innate ; lowest pair of pinnae shorter 

 than the second, third, fourth or fifth, pinnse pinnate ; pin- 

 nules pmnate or pinnatifid; ultimate divisions serrated, 

 spined ; all the di\dsions of the frond convex ; involucre 

 nearly circular, fringed Avitli stalked glands ; clusters of 

 capsules circular, covering every part of the frond. 



Common everywhere. 



Obs. — Two or more doubtful species of Lophodium occupy this 

 place ; viz., L. glandulosum, probably identical, as suggested to me by 

 Mr. Moore, with Lastrea maciilata of Dealdu, L. colHnum, &c. The 

 characters of these are still iusufficiently asceilaiaed.
