JANUARY, 1900.] THE ORCHID REVIEW. II 
months they will get infested with a small scale, which if not carefully 
sponged off soon disfigures the leaves, causing them to turn yellow. If 
neglected this soon spreads, and ants will distribute it over the whole of a 
plant or a batch of plants if not checked. Spraying occasionally with a 
good insecticide will keep them in check and save a lot of sponging, other- 
wise they are not troubled with insect pests. They are not difficult plants to 
grow, and their beautiful and curious flowers are always admired, and for 
the most part remain long in perfection. 
C@LOGYNE CRISTATA, and its varieties alba, Lemoniana, Trentham 
var., &c., will soon be flowering, in a temperature of 65°, and will last a 
considerable time in perfection. Give enough water to keep the bulbs 
plump, or the flowers will be small, and the plants will suffer if flowers are 
left on long. Where the flowers are wanted for decorative purposes the 
plants must be kept in a plump condition, or it will take a long time to pull 
them round again after they have flowered. These are generally termed old- 
fashioned Orchids, still where white flowers are wanted in quantity, they 
are very hard to beat. As a winter-flowering Orchid I do not see much 
chance of their being replaced by any hybrids, especially at the price 
Coelogynes can be bought at, and they will grow in a cold frame during 
summer, only requiring heat during winter and at their flowering season. 
Scale seems to be the only thing that bothers them, and this can easily be 
kept down by spraying. 
MILTonIAs.—Miltonia vexillaria, Roezlii, and X Bleuana will be growing 
freely now the days are getting lighter, and will make stronger growths. 
Leaves which have been made during dull weather, and are weak, will soon 
strengthen with sunlight to help them, and a little ventilation will give them 
that bronzy colour so much admired by growers of these beautiful flowers. 
Those plants that were potted in the autumn will be well-established by 
now, and will require an abundance of water at the roots, as the sun will 
soon help to dry them, and fire heat has to be used pretty strong yet. 
Although the sun gives a little help in the middle of the day it soon loses 
its power, and it is not advisable to drop the fires much until next month. 
Thrip must be carefully watched for, and the plants sprayed or fumigated 
as soon as any are seen. The best plan is to spray occasionally and pre- 
vent them from making any appearance at all, for it saves a lot of trouble 
and at the same time prevents the plants from being disfigured. Frequently 
in dull weather the young leaves will be seen to be stuck together, and if 
not released wili be crippled. The handle of a budding knife or thumb 
nail run gently along the leaves will release them. A temperature of 60° 
to 65° will suit them, but M. Roezlii will grow best in stove temperature. 
Keep a moist growing atmosphere, and ventilate whenever possible. A 
light spraying overhead on fine days will keep the leaves fresh, and also
