ADDENDA. 



A considerable time having elapsed since the pre- 

 ceding Enumeration was prepared and sent to the 

 press, has enabled me to note a number of recently 

 introduced, and a few omitted older species, which I 

 now enumerate in the form of addenda. 



N.B. — Those marked thus f after the name of the country 

 are entered on the authority of Mr. T. Moore's notices of them, 

 in the Proceedings of the Royal Horticultwal Society and the 

 Gardeners' Chronicle newspaper ; not having myself seen them 

 alive or obtained specimens.
