An experimental ground, established nearly six years 

 is situated behind the low conservatories of the garden. 

 This ground already offers many advantages for the study 

 of the various diseases of plants and also for the cultiva- 

 tion and determination of parasitical mushrooms. 



Collections of plants growing in hot houses are attached 

 to section I. The winter garden contains a series of fine 

 tree ferns. The conservatory of the Victoria Regia pos- 

 sesses a good series of aquatic plants and creepers, as 

 does also the conservatory of the^aroidae. 



The collections of open air plants and of plants living in 

 cold conservatories are in section III. 



The schools of botany contain thousands of choice plants 

 grouped in such a way as to represent the largest number 

 of different kinds. 



The conservatory of Cactei is also worthy of notice. 



N. B. Photographic views of the conservatories of the Botanic 

 Garden of Brussels have been published in an album; it can be
