NOVEMBER, 1915. | THE ORCHID REVIEW. 335 
Intermediate house plant—are well worth growing, the plants of some 
varieties being nearly pure white, many in number, and delightfully scented 
during the night. Plants of these species will now be flowering in various 
collections. Water must be given less frequently to L. leucantha, 
aromatica, Deppei, and cruenta. 
PLEIONES.—The Pleiones mentioned in a former Calendar will in a few 
weeks’ time have passed out of flower, and immediately after this the new 
roots will begin to push out from the green shoots from which the flowers 
have sprung. After the flowers are over the plants should be repotted. 
Shallow pans that can be suspended well up to the light are quite suitable, 
and ample drainage is necessary, as the plants need plenty of water when 
growing freely. The potting compost should consist. of fibrous loam, 
chopped osmunda fibre, and sphagnum moss, in equal parts, well mixed 
with broken crocks and coarse silver sand. After being repotted the plants 
should receive little or no water for several weeks, and afterwards only 
enough to keep the compost moist, but when in full growth afford water 
copiously. A light airy position in the Intermediate house is the place for 
them. Pleione humilis and P. Hookeriana will now have finished their 
growth, so keep them suspended in the Cool house, and water often enough 
to keep the soil just moist. Their flowering season is February. The rare 
P. yunnanensis should be treated likewise. 
SOBRALIAS.—The majority of the Sobralias will now be making many 
large roots from the base of their young growths, and in order to obtain 
Strong flowering growths these roots must have something nourishing to 
gtow in. All pot-bound plants should at once have a liberal shift, and 
large unwieldy specimens may be divided. Drain the pots to about a 
quarter of their depth, pot moderately firmly with the mixture recommended 
for the Pleiones. After root disturbance afford water carefully, and when 
well established avoid dryness at any time. Grow the plants in a light 
Position in the Intermediate house. It is as yet a little too early in the 
Season to remove this year’s flowering breaks, but as soon as the leaves on 
those stems change colour, cut them down to the roots, afterwards tie out 
the young growths clear of each other, so that light and air may pass freely 
between them. 
CymBIDIUMs.—Strong plants of C. Lowianum, C. Lowianum-eburneum, 
and others that have made their growth and are not showing their flower 
spikes, should be kept for some weeks longer on the dry side, otherwise they 
will start away into growth, and fail to produce their flowers. Thoae 
already showing their spikes should receive every encouragement. In either 
case keep the plants on the lightest side of the Intermediate house, with 
their foliage well up to the roof glass. Pot-bound specimens are more likely 
to bloom than those which were repotted in the spring.
