Polypodium (Eupolyfodium) Sprucei, Hook. 



Nanum, caudice brevi subfiliformi repente, stipitibus dense 

 csespitosis vix bilinearibus, frondibus membranaceis subun- 

 ciam longis oblongo-subspathulatis obtusis indivisis in- 

 tegerrimis utrinque marginibus stipitibusque villis longis 

 ferrugineis basi latioribus scariosis pilosis, costa gracili flex- 

 uosa, venis obliquis remotis simplicibus apice clavatis intra 

 marginem terminantibus, soris paucis in apicem venarum 

 superiorum globosis. 



Hab. Near Tarapota, Eastern Peru, Spruce, n. 4746. 



I do not find, anywhere described, a species which will agree 

 with this ; notwithstanding, the valuable " Enumeratio Speci- 

 erum " of the Genus Polypodium, lately published by Met- 

 tenius, in which he enumerates 268 species : but, in so doing 

 he considers Polypodium in its more extended, or I may say, 

 Willdenovian sense; omitting, however, Phegopteris, of which, 

 he has a separate "Enumeratio," of no less importance.
