102 THE ORCHID REVIEW. [APRIL, 1916. 
the new material, more liberal supplies may be given. From the time 
that the plants are established until their pseudobulbs are fully developed a 
hot, moist buoyant atmosphere is necessary. Each year a few pseudobulbs 
of the best varieties should be cut up for propagation purposes. The stems 
should be severed between the nodes, and several portions may be placed 
in small pots filled with silver sand, placing them in a warm propagating 
frame, and when new growths appear, and are making roots, they may be 
repotted in small pots singly, and treated in the same way as established 
plants. There are many fine hybrids amongst the spring-flowering section, 
and I may be able to deal with them at some future time. 
OTHER WaRM HOUSE ORcHIDs that thrive in the same house as 
Dendrobiums include Mormodes,.Catasetums, Cycnoches, Schomburgkias, 
and Thunias, and all like a decided resting season. They are best 
repotted annually, and with the exception of the Thunias, will succeed in 
the same material as Dendrobiums. 
LycasTEes.—Plants of this genus, species and hybrids, will develop new 
growths as they pass out of flower, and those that are in need of new 
rooting material should have attention. As regard hybrids, it is rather 
surprising that more have not been raised, considering what advances the 
few we have are upon the parents used. Specimens that are pot-bound 
should be given larger pots, sufficient to accommodate them for at least two 
seasons. Plants that have been enfeebled, either from the loss of roots or 
any other cause, should be carefully shaken out and placed in pots just 
large enough to hold them. Lycastes succeed in a similar compost to the 
green-leaved Cypripediums, and should be grown in the Cool Intermediate 
house. 
CATTLEYAS AND ALLIES.—These at the present time are perhaps the most 
popular of all Orchids, and rightly so, for their gorgeous flowers are always 
appreciated for any kind of decorative work. If the different species and 
hybrids are potted when they are about to push roots from the base of the 
pseudobulbs, and treated as advised in previous numbers, good results will 
accrue. No plants resent more a stuffy close atmosphere. 
La.ias of the anceps section that are in need of new rooting material 
should be attended to at once, as, if the new roots attain any length, there 
is danger of their getting broken, and the plants receiving a check. 
MILTONIA VEXILLARIA, and its numerous hybrids that are pushing up 
their flower spikes, must have water whenever they become dry. The Cool 
Intermediate house is an ideal place for them at this season. 
Catocyne cristaTa.If this old favourite is in need of new material it 
should have attention when the new growths are about to push forth habe 
roots. A compost similar to that used for the green-leaved Cypripediums 
will answer their requirements. Any other Ccelogynes that have passed
