PoLYPoDIUM MacROcARPUM, Presi. 
Humile coriaceum, frondibus oblongo-ovatis obtusis profunde 
pinnatifidis subtus stipiteque equilongo squamis ovatis 
acuminatis peltatis serratis paleaceis, soris rotundatis majus- 
ulis demum confluentibus, caudice longe repente squa- 
moso.

When this figure was drawn from a specimen gathered at 
Massa Fuera, South Pacific, in a latitude corresponding with 
Valparaiso, I little suspected it would prove the same as 
Pleopeltis pinnatifida, Gillies in Icones Filicum; but such 
proves to be the case, and further that this is identical with 
the Polypodium macrocarpum of Presl, a name which should 
unquestionably, on every account, be preferred. It is a true 
Polypodium, of the same group as our Polypodium vulgare, 
and we are now able to give some additional habitats for this 
widely extended species. Some of our specimens, from the 
Andes of Ticicaca, (14,000 feet above the level of the sea), 
have the fronds exactly spathulate, a little lobed at the base: 
but this is to be considered as an abnormal form, and from 
this we have all the intermediate states to the many lobed 
and elongated form given in the Icones Filicum.
