LEUCOSTEGIA CHJEROPHYLLA 

 (Chervil-leaved). An East -Indian 

 Fern, having light delicate green 

 fronds, which are about a foot or 18 

 inches long ; they are cut up into fine 

 segments, and are somewhat erect. 



L. IMMEESA (Imbedded, referring 

 to the sori), Fig. 36. The pale green 

 fronds of this Fern hang somewhat 

 horizontally, spreading out almost flat, 

 with the points drooping. The fronds 

 are repeatedly divided, but not into 

 such fine segments as the last-named 

 plant. There is a little pouch-like 

 swelling above the spore-masses on 

 the upper sides of the fronds. 



There is a third species sometimes 

 met with in gardens, and called L. 

 pulcJier (the beautiful). 



LINDS^A. 



This name is commemorative of 

 Mr. Lindsay, a cryptogamist. This 

 is a very extensive tropical genus, 

 most of the species of which are as
