themselves and not placed amongst other 
Orchids in bloom. 
Cattleyas and allied subjects. Not many 
species of these beautiful plants are in flower 
at this season of the year. With Laelio- 
Cattleyas, however, things are different, and 
it is now possible to make a display of bloom 
all through the winter, a condition regarded 
as impossible only a few years back. All 
these plants, together with their allies, should 
be afforded a light position in the Cattleya 
house, and, after flowering, should be kept on 
the dry side until growth recommences. The 
plants may be repotted whenever they are 
seen to be pushing new roots, using a 
compost as previously advised. Cattleya 
Percivaliana and C. Trianae whilst pushing 
up their flower spikes must have water when- 
ever they become dry. Every inducement 
should be given them by placing the plants 
in the lightest position possible. 
Plants of Cattleya Warneri starting into 
growth should also enjoy the lightest and 
warmest position and remain there until the 
flowers open. These remarks apply also to 
C. Warneri alba, the white hybrids derived 
from this species, such as Mrs. Myra Peeters, 
C. intertexta alba and C. Mullen. Repotting 
should be done after the flowers fade for at 
that time numerous young roots push out 
from the base of the newly made pseudo- 
bulbs. 
Phalsnopsis. During the winter months 
there are few Orchids more difficult to 
manage, for owing to their succulent leaves, 
which are very susceptible to injury, and 
having no pseudo-bulbs to store up nourish- 
ment, watchfulness on the part of the grower 
is ver}' necessar}-. If the leaves are properly 
consolidated the plants should be able to 
withstand the dryness at the roots and of the 
atmosphere which is necessary to carry them 
safely through the winter. Specimens having 
soft ill-matured foliage should not be sub- 
jected to the same treatment as those that are 
properly ripened, they should be kept in a 
warm temperature until the leaves are fully 
developed. Well matured plants should 
receive during the winter a minimum tem- 
perature of 58 to 60 degrees, but no harm will 
accrue if a fall of a few degrees occurs 
temporarily during extremely cold nights. 
The plants should receive all the light 
possible without being placed too near the 
glass, a necessary precaution for the leaves 
are very susceptible to a sudden chill. Every 
care is necessary in affording water to the 
roots ; only sufficient is required to keep the 
leaves plump and firm. Plants should never 
be allowed to suffer from excessive dryness 
during the winter months, for when growth 
commences in spring many of the leaves will 
be lost. Care is also necessary to guard 
against the other extreme, for an excess of 
moisture will cause damping and spotting of 
the foliage. If the house cannot entirely be 
devoted to their culture the next best means 
is to group the plants together in a house 
answering their requirements. 
Vanda teres and V. Hookeriana. These 
beautiful Vandas require treatment different 
from others of their family. The sealing over 
of the points of the roots is a sign that growth 
is completed. These Orchids require a long 
season of rest when water should be afforded 
in only sufficient quantities to prevent 
shrivelling. The temperature of an inter- 
mediate house, such as the majority of 
Cattleyas enjoy, will answer their require- 
ments at this season much better than a house 
with a warmer temperature. Vanda Amesiana, 
V. Watsonii, and V. Kimballiana are now 
pushing up their flower spikes, and as winter 
flowering subjects are very useful and beau- 
tiful. The plants, as soon as the flowers are 
over, pass through a brief period of rest, little 
water will be required, but the plants must 
not be allowed to shrivel, for this miscalled 
resting system is most harmful. V andas of 
the tricolor section are fast growing and 
should be well .supplied with water. Any 
recently repotted plants should have their 
flower spikes removed. Keep their surround- 
ings always moist, and, if possible, conduct 
any aerial roots into the compost. The plants 
enjoy a circulation of fresh air at all times. 
Miltonia vexillaria and its hybrids. These 
delightful Orchids, now in full growth, should 
be in a light position in the intermediate 
house. Care should be taken that the supply
