ONCIDIUM CRISP ITM GRANDIFLORUM. 
We .'ire indebted to Mr. William Bull, of the King’s Boad, 
Chelsea, who has lately greatly extended his orchid culture, for 
the opportunity of figuring this fine variety of Oncidium, 
which has been so faithfully rendered by our artist Mr. 
Smith. 
The increased attention that has been given lately to 
the growth of orchidaceous plants is due in some measure to 
the fact that it has been found that many of the most beauti- 
ful species will bear a much lower temperature than used to be 
considered necessary. It was not merely that amateurs 
grudged in many cases the excessive cost of keeping up the 
highly heated orchid-houses ; but that, if they themselves took 
an interest in them, it became very fatiguing to be in them for 
any length of time ; and hence, when the cool orchid treatment 
was demonstrated to be a success, many were induced to com- 
mence or extend their growth. 
We have lately alluded to the new orchid-house built by 
Mr. Bull — in itself a sufficient indication of their universal 
growth ; and last month had the pleasure of seeing a new 
house built by our friend Mr. Charles Leach of Clapham Park, 
the well-known successful cultivator of Disa grandiflora, and we 
then saw a number of orchids contenting themselves with a 
temperature which a few years ago would have been considered 
death to them ; and the same thing is being reproduced in 
many places.
