sheltered drawn out and elongated. These extreme 
states are ranked as varieties. Some have been found 
also with the fronds variegated with white. It seems 
to be nearly as common as the Athyriums , though not 
growing to so great an elevation, for it is found nearly 
everywhere, from Scandinavia to the Cape of Grood 
Hope, in the Sandwich Islands, in Affghanistan, in 
Java, and in St. Helena. It thrives moderately well 
in cultivation if planted in a sandy soil and well 
drained ; and is easily manageable as a pot-plant, but 
requires a pure atmosphere. It is common through- 
out the Lake Country, either on the slate or limestone, 
often preferring old walls.
