332 THE ORCHID REVIEW. [NOVEMBER, 1909. 
good syringing on a nice day will doa lot more good than watering them 
too often at the roots, and the house will soon dry again if a nice day is 
chosen when the ventilators can be used. D. Dalhousieanum, fimbriatum, 
Gibsoni and others of this section must not be given lower than Cattleya 
house temperature if good results are to be obtained. These are better 
given stove treatment until they have finished growing, when they can be 
removed to the Cattleya house or a similar temperature. 
DENDROBIUM DEAREI which was -imported in the spring and potted up 
should now be making fine growths. Those which were potted in very 
small pots and have overgrown them should be shifted into larger pots as 
soon as they make new roots. A mixture of Osmunda fibre and leaves 
should be used, with plenty of crushed crocks to keep it porous, as this 
species likes plenty of water during its growing season. When the plants 
are strong they are almost always in bloom, and, like all white flowers, are 
always admired, and are very useful for buttonholes. Many of the imported 
bulbs will push flower spikes. These species should be given warm treat- 
ment, and not too much sun. The shady end the Stove seems to suit 
them better than a more sunny position. 
DENDROBIUM PHAL2NopPsIs and D. FoRMosUM, as they finish flowering, 
can be given a slightly lower temperature. A sunny position in the Cattleya 
house suits them during the winter, and only sufficient water should be given 
to keep the bulbs plump. D. Jamesianum and infundibulum are two very 
beautiful species which often receive Cool house treatment, but I find that 
they do much better in a temperature of 60° as an average, both during 
their growing and resting season, with plenty of sun at all times. They 
then make fine growths, and I find that the leaves do not spot. Do not 
overpot them, as they are small rooting varieties. They are irregular in 
blooming, and when the plants are strong, their season of flowering is often 
extended over several months. The flowers are large, and make a fine 
show, as the plants are evergreen and the flowers look well against the dark 
green foliage. They should not be dried quite so much as the D. nobile 
section, as if the bulbs are allowed to shrivel much they soon get into bad 
health. 
CaTTLEyas and La:tias.—The species will nearly all have finished 
their growths, and must be very carefully watered for some time. Do not 
water a plant unless it really wants it; then give it a good watering. Do 
not be tempted when going through the plants to water half dry plants; if 
they are looked over for water twice a week now it will be sufficient, and 
the temptation of watering half-dry plants will not be so great. If they are 
not dry leave them until the next watering, and they will take no harm in 
fact, it will rather benefit them. A Cattleya or Lelia which is kept on the 
dry side after it has completed its growth will make many more roots than
