332 THE ORCHID REVIEW. [NOVEMBER, 1907. 
we find that if the plants are allowed to develop their spikes there they 
generally come crippled and disfigured, whereas when taken to a warmer 
and lighter structure they develop clean and well-formed flowers. 
_ CYMBIDIUM GRANDIFLORUM.—The flower-spikes are now running out 
well on this grand species, and it should be given a very light position. 
So far we have never known our buds to fail, and as the plants were from 
different sources, and not from one stock, I have rightly or wrongly 
put it down to us having a strong light at Gatton, and taking full 
advantage of it. It must be very disappointing to fail to flower this 
magnificient Orchid, yet I believe such failures occur year after year. 
Taking for granted that the plants now showing spikes are strong and well 
rooted, and are given a position where all available light can reach them in 
the Odontoglossum house temperature, I believe that in most cases the 
spikes will develop fully. I can quite understand the buds falling near 
large towns from the effect of town fogs. I should be very interested 
to know of any failures that may occur this winter on plants in good 
condition, for I believe such points as this may be cleared up if we would 
only record our failures, giving full particulars of the compost used, 
temperature of house, &c. 
VANDAS AND AERIDES.—These will now need little direct watering ; slight 
damping between the pots will generally suffice, though -sometimes, 
especially if the house is of a very dry nature, they may become too dry. 
In that case only give enough to moisten the surface material, for it 1S 
rather more a case of keeping the moss alive than of helping the Orchid. 
The beautiful Vanda teres should be given a very light position, as we 
have few plants that resent our short dull days more than these. They 
always require a position where much light can reach them, and at no time 
is it more important than during the winter, although they are practically 
lying dormant. 
Exactly contrary to V. teres is V., or Arachnanthe, Cathcartii, which 1s 
now developing its spike. I find the most shady and damp positions the 
most suitable at all seasons; also if the plants can be placed a long way 
from the glass so much the better. Ours are grown over a tank on the 
back wall of a lean-to Nepenthes house. To see the flower properly it is 
necessary to place the plant on a stage in the front of the same house, and 
we have noticed each year after the plant has been moved from its corner 
that the leaves soon take on a yellow appearance. Another case I have in 
my mind respecting this beautiful variety was some plants that had been 
placed overa tanlt—I should say many years previous—and had been quite 
neglected. The plants had fallen over, and were practically growing 
horizontally below the level of the edge of the tank, and I think I must Say 
they were the best plants of this species I ever saw.
