CYPRIPEDIUMS will be making a fine show during this month, and if the 
flowers are well cared for will continue good far into December. Where a 
house cannot be set apart for them while they are in bloom, the houses in 
which they are placed should be kept slightly drier, or the flowers soon go 
thin, and the more delicate will soon spot. It is worth the trouble to stage 
the plants which are in bloom by themselves in a separate house, leaving 
those that are growing in a house by themselves. Cypripediums do not 
appeal to everyone, when seen flowering in the growing houses dotted about 
singly, but when they are massed and nicely staged with ferns and other 
foliage plants the endless variety is wonderful, and the varieties can be 
more easily distinguished. It is also much easier to compare varieties than 
‘when they are scattered about the houses. Cypripediums, unlike most 
Orchids, must not be dried off when in bloom. Watering must still be 
carefully attended to, and a plant should never be allowed to get dust dry, 
or it will soon get into a poor state, and will take a lot of pulling round 
again. When the leaves are allowed to shrivel thrip will soon make head- 
way, and if not checked will spoil the whole of the young leaves. Wherea 
house is ‘used for flowering they can all be kept at a temperature of 55° at 
night, and 60° as a day average, provided of course that the house is not too 
heavily charged with moisture. The house should be ventilated on every 
favourable day. These temperatures will also suit Cattleyas, Odonto- 
glossums, Oncidiums, &c., when in flower, and the flowers will last much 
longer. 
DENDROBIUMS of practically all the spring flowering section will now 
have finished their growths, and will need very careful watering until they 
-are again in their growing quarters. D.aureum and its hybrids will be 
pushing their buds up, but should still be kept in the Cool house until the 
buds are well advanced. Then they can be put in a warmer house if wanted 
for early flowering. If they are placed in strong heat before the buds are 
well advanced, these will in most cases turn yellow and drop, and the plant 
will go into growth. D. nobile, D. Wardianum and their hybrids should 
be kept as dry as possible without shrivelling the bulbs, to prevent them 
from starting into growth. D. thyrsiflorum and densiflorum should also be 
given similar treatment. Keep the glass clean to let them have as much 
light as possible, and ventilate whenever the outside conditions will allow. 
‘These should be given a temperature of 55° at night and 60° by day. A
