THE ALTERNATE-LEAVED SPLEENWORT 



in a narrow fan-like manner in each 

 of the larger pinnse, the smaller hav- 

 ing proportionally fewer. Two or 

 three linear sori are produced on a 

 pinna, covered by membranous in- 

 dusia, the free margin of which is 

 entire, or slightly sinuous, but not 

 jagged. The sori at length become 

 confluent. It is very difficult of 

 cultivation. 



For the cultivation of A. germani- 

 cum, Moore (our chief authority) 

 recommends that it should be potted 

 in sandy peat-soil, well drained by a 

 mixture of rubbly matter (indeed, 

 good drainage seems indispensable to 

 almost all of the Fern kind) ; and that it should* be 

 kept under a bell-glass in a shaded frame or greenhouse. 

 The plants are very liable to die in winter, the best 

 safeguard from which is not to allow any water to 

 lodge about the crowns, nor to keep the bell-glass too 

 closely or too constantly over them.
