FERNS OF THE LAKE GrorGE Fiora—II 101 
A delicate, heavily-scented fern, more often found in 
newly cleared land at higher elevations. In late autumn, 
the fronds sometimes turn white. 
FILrx BULBIFERA (L.) Underw. 
Shaded cliffs ledges, specially near limestone; 
frequent. July—Sep 
A handsome oe fern, with shorter and broader 
sterile fronds than the long lanceolate fertile ones. The 
young stipes are often reddish. This fern is usually 
propagated by the little greenish bulblets, borne loosely 
on the back of the pinnules among the sori. 
Fux rraqiuis (L.) Underw. 
Shaded rocks and cliffs; common, especially near

fronds of this handsome evergreen fern are erect: 
but become early semi-prostrate. Some plants bear
