Thi$ species ranges througbout the tropics and subtropics of both bemisphcrcSj extending in latitude 
from the Cape of Good Hope to the shores of the Mediterranean^ flourishing under great diversity of cli- 
mate, both as regards temperature and moisture. In the island of Ischia it grows in company with Cyperus 
polystachifs^ within the influence of the hot vapour issuing from the steam-holes of the extinct volcano, in 
Boil at a temperature of from 140^ to XQl^ Fain*. In a state of cultivation its spores vegetate in such pro* 
fusion as to become a pest in hothouses. It is common in the West India Islands^ and is found in Mexico, 
but, with the exception of Veue7Aiclaj it has not been found in any other part of South America.

This has probably a wider geographical distribution than the preceding species. The fronds vary much 
in size, and in the pinnse being variously divided, which has given rise to several of the states having been 
described as distinct species.
