Ops. — A remarkable Fern lias of late years appeared in 

 garden collections under the name of A. Farleyense, it has 

 the same habit as A. tenerum, but is much larger in size 

 and in all its parts, and which has led it to become a 

 favourite exhibition plant, it however does not pi-oduce 

 fructification, and there being no wild specimens in herbaria, 

 it is, therefore, supposed to be a hybrid, and to have 

 originated in a garden in Barbadoes.
