460 THE ORCHID REVIEW. [Sept.-OcT., 1919, 
Keep the atmosphere rather dry when the first blooms open, and all 
-damping between the pots should cease. Calanthes are excellent subjects 
from the decorative standpoint, and remain in full beauty for a considerable 
time when cut. 
Vanpas.—At the present day these handsome plants are not generally 
cultivated, but to those who do grow and appreciate them, the following 
note may be useful. The end of October, or the beginning of November, is 
the best time of the year to overhaul Vandas of the V. tricolor and suavis 
section. The plants now commence to root freely, and continue to do so 
‘throughout the winter months, so that the foliage will suffer less than if the 
work is left over until the spring. If the plants are well furnished with 
leaves, it is not advisable to disturb them by repotting, unless they have 
“outgrown their receptacles. But if repotting is necessary because of loss of 
leaves at the base, or of decomposed material, the old compost and drainage 
‘should be removed, and if there are plenty of live roots some distance up 
the stem, so much of the lower part of it may be cut away as will bring the 
lowest pair of leaves on a level with the new material when again placed in 
the pot. Clean live sphagnum moss, mixed with small broken crocks, 
makes a suitable compost, which must be pressed firmly, and the drainage 
should be ample. The compost placed in the pots of this class of plants is 
more to hold them in position, and keep a supply of moisture around them, 
than asa supply of nutriment. These Vandas require a somewhat cool 
intermediate temperature. I have always found them to grow and bloom 
quite satisfactorily when staged on a damp bottom by themselves at one 
end of a Cattleya house. 
CyprIpEpIuMs, which are now pushing up their flower spikes, should be 
carefully staked as the stems attain sufficient length, and any that are in 
need of cleaning should have attention. The plants can then be arranged 
in the house in which they are to bloom, and there they may remain until 
the early spring months, when the potting season comes round again. Any 
‘Cypripediums which produce flowers during the summer, such as C. 
superbiens, C. callosum, and its variety Sanderz, may still be repotted 
should they require it. Peat fibre and sphagnum moss in equal quantities 
makes a suitable compost for these plants; Not being strong-rooting plants, 
they should not be placed in large receptacles. They succeed when grown | 
in a Cattleya house temperature, and water should be applied with caution 
until they become re-established. : e 
DENDRoBIUMS that have finished their growths should be thoroughly 
cleaned, and placed in their winter quarters in the resting house. This is 
asily accomplished now that they have all attained that condition, and ‘if 
the house and plants are thoroughly cleaned they should not be much 
trouble until their flowering nodes begin to swell in the spring. Sufficient
