the Brit'i/h Fiici, wilh particular Defcriptlom of each Species. wj 



tions between this and dafyphyllus are fufEciently pointed out under 

 that fpecies. 



From the fpecific chara6tcrs and defcriptions given of this 

 plant, and Jedoides which follows it, they cannot but be confi- 

 dcred as perfedly diftinft ; but a confufion has arifen from Mr. 

 Hudfon's having quoted two different fpecies of Gmelin for this 

 plant, which was probably occafioned by his having never kta 

 fedoides. Mr. Lightfoot certainly confidered them as diftinft, having' 

 quoted Gmelin's vertnlcularii, and taken no notice whatfoever of his- 

 polypodjoidts, or the avails of Hudfon. 



That the p'ilypodloides oi GmeWn ought to be referred to this fpe- 

 cies cannot be doubted, when it is confidered that he inferts it folely 

 on the authority of Martyn, whofe figure is very indifferent, and who 

 has given no defcription. As to his defciibing the K aves as membra- 

 naceous inftead of flelhy, that ought to have no weight, as the 

 dried fpecimens muft always have that appearance. It is owing to 

 this alfo that Gmelin has erroneoufly placed this fpecies amongft 

 his membranaceous fuciy when it certainly ought to have been 

 placed next to vermicularis. 



.Sometimes largifh folitary tubercles are obferved adhering to the 

 main branches and to the leaves alfo. This we deem the true form 

 of the frudtification. It is very rarely to be met with in this fitua- 

 tion..
