16 THE ORCHID REVIEW. [JANUARY, Ig10. 
Intermediate house till March, giving them very little water, when they 
may be placed with the older-established plants for the rest of the season. 
Do not on any account try to force them into growth. A good compost for 
potting them in is half each of Osmunda fibre and sphagnum moss, well 
mixed together, and chopped about half an inch long, or, if preferred, 
Osmunda fibre may be used alone. I find that they do very well in either. 
CaTTLEyAs will mostly be at rest. C. Trianz and its varieties, and C. 
Percivaliana, are pushing up their flower buds, and should have a little more 
water, but as soon as the flowers are over give little or no water till they 
commence to make new growths. C. intermedia and C. Warneri are now 
pushing new growths, but should not be hastened in any way. Let them 
grow steadily, with only enough water to keep them moving gently, or else 
they will make weak growth and the blooms will be unsatisfactory. 
OpoNnTOGLOossuMs.—In the Odontoglossum house we find most of the 
plants in full growth, and some are in flower, while a good many are 
throwing up spikes. I think these are the most useful Orchid we have. If 
one has a good collection, both in number and varieties, one is rarely 
then without a few spikes to look at. Practically they flower twice in 
eighteen months when properly grown. If any plants require repotting 
they can safely be done now, when the young growths are about one-and- 
a-half inches high. Fill the pot about one-third with crocks, and use a 
compost of polypodium fibre and sphagnum, half of each, chopped about 
half-an-inch long and thoroughly mixed together. It should be well 
moistened a day or two before using. Pot firmly, but do not put it in 
lumps. They will require very little water till they are well rooted. Do 
not let the thermometer get above 55° with fire heat in the day time, or 
below 48° at night. If a bright day 60° will do no harm when it is run up 
by the sun, so long as you have plenty of bottom ventilation. 
INTERMEDIATE HouseE.—Ccelogyne cristata and its varieties are now 
pushing up their flowers, and should be accorded enough water to keep 
them plump. If allowed to shrivel the flowers will be weak, and flag as 
soon as they are cut. Odontoglossum citrosmum is now at rest, and the 
plants should be suspended near the glass, and kept quite dry till the 
flower spikes show from the young growth. Cypripediums of the insigne 
class do well in this house. 
TEMPERATURES for the month should be maintained as nearly as 
-possible at the following figures, using judgment according to outside 
conditions :— 
Cypripedium house: Day, 65° to 70; night, 65°; morning, 60°. 
Cattleya house: Day, 62° to 68° ; night, 62°; morning, 58°, 
Intermediate house: Day, 60° to 65°; night, 60°; morning, 55°. 
Odontoglossum house: Day, 55° to 60°; night, 53° ; morning, 50°.
