 scales ; frond elongate, triangular (being exactly that of 

 Asplenium Adiantum-nigrum), drooping, elegant, pale de- 

 licate green when young, its under sm'face sprinkled over 

 with sessile, pellucid glands (which probably cause the pow- 

 erful scent for which this species is remarkable), pinnate ;

 divisions of the frond concave ; involucre jagged, without 

 stalked glands ; clusters of capsules round, crowded, cover-

LOPHODIUM MULTIFLORUM. 



Polypodium cristatum, Linn. Sp. PI. 1551, ad partem ; 

 Huds. Ft. Ang. 390 (1762), (I place this sj'nonyme 

 here without hesitation, not simply from the accord- 

 ance of Hudson's specific character, but because that 

 author specially cites Hampstead Heath as the loca- 

 lity, and the present species has existed there from 

 Hudson's time to the present, and no other form or 

 supposed species has ever been found there) ; Id. 4:57, 

 (1778); Light/. Fl. Scot. 670; Bolt. Fil. Brit. 42, ad 

 partem, (the second variety refers to this species);
