Hab. Andes of Quito, on the banks of the river Hondacha, 
Jameson, n. 780. On Mount Picote, near Moyobambu; 
Peru, C. W. Nilson (in Spruce's Plants of Peru, n. 4780 ). 
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 ee, but that has much narrower 
fronds, deeply pinnatifid, the lobes 1-veined, and the sorus 
placed within the lobe.
