The research work of Kew is principally economic and 
taxonomic. Around it centre the twenty-four botanical gar- 
dens and botanical stations of the British colonies, which are 
manned chiefly by men who have studied or worked at Kew. 
The principal publications at present emanating from Kew 
are: 
The Kew Bulletin of Miscellaneous Information. 
Hooker’s Icones Plantarum. 
The Continuation of Hooker’s Flora of India.
