DECEMBER, 1912.]} THE ORCHID REVIEW. 363: 
Among Cattleyas that bloom late in the spring may be mentioned C.. 
Warneri. Plants of this species will now be showing signs of activity, both 
new growths and roots pushing freely. They should be placed in a position 
well up to the light, and, like the preceding, have water applied to them 
whenever the compost becomes dry. There are other plants in the Cattleya 
house which are in various stages of growth, including Lelia crispa, L. 
purpurata, and L. tenebrosa, which must be watered with discretion. 
L4&LIA HARPOPHYLLA, whilst in full growth, will require plentiful 
supplies of water, but when growth is completed and the flowers are past 
much less will suffice, and the plants should be induced to rest by placing 
them under cooler conditions. 
SOPHROCATTLEYAS.— Under this head can be placed all those hybrids 
which have been obtained by intercrossing Sophronitis with species of 
Cattleya, Lelia, and the hybrid Leeliocattleyas. These numerous forms. 
have flowers of most vivid colour, which bloom at different seasons of the 
year, and a collection of these plants will rarely be without one or more in 
flower. Those which have recently bloomed and are commencing to grow 
and pushing new roots may be repotted if they require it, using a compost 
as for Cattleyas. The majority of them succeed in a light, warm position 
in the Intermediate house. They must be judiciously watered at all times,. 
as the young growths decay and turn black if the compost is watered. 
indiscriminately. These plants are best grown suspended where no water 
from the syringe can reach them, as overhead waterings to them is highly 
injurious, but water at the roots must be given when necessary. 
CypriPpEDIUMS.—Members of this genus belonging to the cooler section 
are amongst the most important Orchids flowering at this season, and it is- 
very questionable whether greater strides have been made with any class of 
plants in recent years than with these. There are varieties at the present 
day of great beauty, and when it is taken into consideration their lasting” 
qualities, and the ease with which they are grown, it is no wonder that they 
are so popular. To those who reside near our large commercial centres- 
they are indispensable, being capable of withstanding fogs better than most 
plants. Cypripediums are never inactive at any season of the year, there- 
fore should never be allowed to remain dry at the root for any length ot 
time, or much injury may accrue. During the winter months much less. 
water will suffice, both at the roots and in the atmosphere, than the plants. 
require when in full growth. When in flower they are best grouped by 
themselves, being more effective than when placed with other Orchids. 
The plants should be carefully examined from time te time for thrip, which, 
if allowed to get a foothold, will soon disfigure the foliage, and make the 
plants quite unsatisfactory. Plants infested with parasites cannot thrive, 
and the mischief soon spreads.
