ee THE ORCHID REVIEW. 
watering-can ; keep the sphagnum growing in this way until the plant has 
re-established itself again, when more water may be given. If the plants 
are not strong, or well rooted, remove their flower-spikes for one season, and 
give them a generous growing treatment throughout the year. All newly- 
imported Aérides should be potted in crocks only, keeping the stems and 
lower leaves well syringed to prevent undue shrivelling. As soon as new 
roots appear, pot as previously advised. 
In the Cattleya, or intermediate, house are principally grown Cattleyas, 
Lelias, Epidendrums, Coelogynes, Miltonias, Sobralias, Cymbidiums, Vanda 
tricolor, and V. suaris; also the cooler growing Cypripedium x Leeanum, 
C.x Harrisianum, C. insigne, and Selenipedium Schlimii. Cattleyas are, 
practically speaking, at rest in January, though C. Trianz and its many 
beautiful forms will now be coming into bloom. They will, therefore, 
require more water at the root to fully develop their flowers. Ccelogyne 
cristata and its varieties will also be flowering. They should receive a good 
watering of liquid cow-manure before the spikes open, to help them through 
their flowering period. When in bloom, very little, or no water must be 
given, as if kept too moist their flowers quickly become spotted. 
Vanda tricolor and V. suavis should be placed at the coolest end of this 
house. Keep the atmosphere around them constantly moist, and give the 
plants a moderate supply of water at the root,’as if kept too dry their leaves 
will shrivel, turn yellow, and fall off. They delight in an abundance of 
fresh air, therefore the ventilators nearest to them should never be entirely 
closed. The best time to re-pot them is about November, and in precisely 
the same way as advised for Aérides. Masdevallias of the Chimera section 
do best in teak baskets, hung close to the roof-glass in this house during the 
cold winter months. They require plenty of water at the root always, and 
-on bright sunny days may be taken down and well syringed with tepid rain- 
water, which not only cleanses the foliage from insects, but helps to ward 
off the much-dreaded black spot. 
The Mexican house will contain such plants as Lelia anceps and its 
many pretty varieties ; also L. autumnalis, L. majalis, L. albida, etc. After 
these plants have done blooming, no time should be lost in supplying them 
with fresh material to root in. Use shallow, well-drained pans or baskets, 
keep the plants well elevated above the rim, and pot firmly with the best 
fibrous peat and moss, using a few large pieces of crock with it, so as to 
allow the water to pass freely through. After re-potting, only enough water 
should be given to prevent them from shrivelling, or the young roots from 
-damping off, as they are very liable to do if too much water is used before 
the plants are re-established. Keep the temperature cool, and on the dry 
side, until the new growths appear, when both may be gradually increased. 
In the cool house, the principal work at this time of the year is watering, 
and thoroughly overlooking and cleansing the plants from all insect pests.
