which must be included among the most 
caution, so as not to wet the flowers, 
charming of Orchids. Their blue colour, analogous with that of Vanda PUES 
is exquisite, their form is nearly circular, and their arrangement in upright 
flexible racemes extremely graceful. 
Aganisia coerulea is not difficult to cultivate, but it requires much heat and 
moisture. 
It succeeds best on a block, because of its creeping rhizome, and should be 
fixed to the wood, so that its pseudobulbs may grow out and elevate themselves 
each year. 
The plants should be cultivated in the warm or intermediate house, and 
by preference in a small low house, where the atmosphere is always charged 
with humidity. They should be syringed frequently, and in a warm season like 
the present one, at least once a day. 
The flowers of Aganisia coerulea remain in good condition for a long time, 
if water be not allowed to touch them, and the flowering is renewed at different 
seasons of the year. It is one of the most beautiful species when cultivated near 
the glass. 
It is not advisable in general to tear away the pellicle which covers the 
pseudobulbs of Cattleyas when they have become fully developed. Sometimes, 
however, these bracts become black and appear to decay, either because water 
has penetrated between them and the pseudobulbs, or the plants have not been 
sufficiently ventilated and exposed to the sun. In such cases it is advisable to 
split the bract throughout its entire length, so that the air may penetrate to the 
interior and arrest the decay; otherwise it may attack the pseudobulbs. 
as best time to divide the plants is just before they begin to grow. At 
this period there is no danger of injuring the roots, as they are not now firmly 
fixed in the compost. ; 
The ens wns have been divided should be placed in a shady part of 
the house, which will favour the development of new roots, and prevent the plants 
from becoming shrivelled. 
Water should be more sparingly given for some time, until they have 
commenced to grow and the young roots are formed. 
t is also advisable to add that in dividing the plants, one or more eyes
