A very pretty and very peculiar species of the extensive 

 Genus Polypodium, of which I do not find any description, 

 and which seems confined to the Andes of Ecuador and 

 Peru ; at least, I have seen it from no other quarter. It is 

 remarkable in the almost ligulate form of the small thin and 

 membranaceous fronds, cut at the margin, with great regu- 

 larity, into very short and obtuse lobes ; the whole, on both 

 surfaces, and at the margin, clothed with long, but rather 

 sparse fulvous hairs. The color is pale green ; in the older 

 specimens stained with yellow and brown. The fronds seem 

 destitute of stipes, and are decurrent to their very base, 

 where the costa is often blackish. It may rank near the 

 West Indian P. Serricula of F£e, but that has much narrower 

 fronds, deeply pinnatifid, the lobes 1 -veined, and the sorus 

 placed within the lobe.
