DECEMBER, 1910.] THE ORCHID REVIEW. 337 
A supply of sphagnum moss should be secured at once, before severe 
weather sets in, so that no delay is caused when potting during the next 
two months, It often happens during that time that the supply of 
sphagnum is frost-bound for weeks, and therefore unobtainable. It will 
keep in good condition for two months if spread thinly in a cold frame or 
similar place and not allowed to get dry. 
TEMPERATURES for the month should be as follows, but the grower 
should use his own judgment in modifying them according to conditions 
prevailing :-— | 
Cypripedium House: day, 65° to 68°; night, 65°; morning, 60°. 
Cattleya House: day, 60° to 65°; night, 60°; morning, 58°. 
Intermediate House: day, 58° to 60°; night, 58°; morning, 55°. 
Odontoglossum House: day, 55° to 58°; night, 55°; morning, 50°. 
If the morning temperatures fall below the figures mentioned above, 
every effort should be made to raise them to the desired point as soon as 
possible, and the houses should not be damped down or any plant watered 
until the temperature is correct. 
ANGULOAS will only require sufficient water to prevent them from 
shrivelling until the new growths are seen pushing from the base of the 
bulb, when they may be repotted. 
BULBOPHYLLUMS are a very peculiar class of Orchids, and always attract 
a great deal of attention from visitors when in flower. They are rather 
‘slow growing plants, but not by any means difficult when given ordinary 
care and attention. A good collection of them should be grown in every 
‘Orchid establishment, as they are very interesting and sure to give pleasure 
to the cultivator, At present in the Warm house B, virescens, Ericssoni, 
grandiflorum and Lobbii are growing freely, and should be placed in the 
lightest possible position until the sun gains in power, when a slight shade 
‘should be given them. 
Brassias form another class of Orchids that is not often included in 
‘collections. It is true that many of them do not attract much attention 
when in flower, owing to their lack of colour, but there are some that are 
well worth growing, and will always attract attention when included in a 
group of flowers. B. caudata, verrucosa, Lawrenceana and maculata 
would be worth including in any collection. Their culture is about the 
same as the warmer sections of Oncidium, and I find that they do best when 
grown at the cool end of the Cattleya house all the year round. 
CATTLEYAS,—C. Percivaliana, the next of the labiata section to flower, 
is now pushing up its flower buds. It isa rather neglected species, owing 
‘to the flowers being rather small, but I think that it will soon come into 
favour again, as some very fine varieties have flowered from recent importa- 
tions, the flowers being much larger than the old type. This Cattleya
