or baskets, and suspended at the hottest part of the house. It is best to 
re-basket, or to pick out the old compost and supply fresh annually, and 
this should be done just as the new growths begin to push forth. D. 
Lowii, D. Bensonie, D. bigibbum, D. Dearei, D. Maccarthie, D. 
macrophyllum, and D. Phalenopsis require similar treatment. A very 
pretty and very cool-growing Orchid in flower just now is Odontoglossum 
X aspersum. It is a natural hybrid between O. maculatum and O. Rossii. 
This hybrid varies very much in detail, like its parents, some forms being 
washy in colour, whilst others have a groundwork of a beautiful golden 
yellow, blotched and barred with bright chestnut-brown, and these are 
great acquisitions to the group. 
I mentioned in my last Calendar a few beautiful Oncidiums which love 
the temperature of the Cool house. There is another section of the same 
genus which I would here mention as doing best in the same department, 
supposing one important point be strictly observed, and that is to see they 
are kept dry after flowering in the autumn, and throughout the winter 
months. I refer to those lovely species which brighten up the house with 
their vivid colours in the dull autumn and early winter months, when there 
are but few other things in bloom, such as O. Forbesii, O. crispum, O. 
varicosum, and its large variety, Rogersii, O. tigrinum, and O.t. 
unguiculatum. With the exception of the last two, these are best grown 
Suspended, and all during the season before mentioned must be given but 
little moisture. They will now, however, begin to grow, and will require 
More water, gradually supplied. They are Orchids that do not take well io 
toot disturbance, but this must be done about once in two years, sai - 
most important their roots should be kept in a sound, healthy condition. 
This operation should be done when the new growths are an inch or so 
igh. 
One of the most useful Ccelogynes is the old and well-known C. cristata, 
and it is very easily cultivated. It is best not to pull this Bpeeies about too 
much when repotting. Unless the pseudobulbs are growing over the rim 
of the pot it will scarcely ever require to be taken out of it, bat simply fill 
in any hollow places with fresh peat and moss, without which the _ 
would in time get loose and shaky, presenting a more or less starv 
appearance, and small under-sized growth resulting. It will now soon 
have finished flowering and will be starting into growth, and t - 
fore the best time to do it up. Coelogynes delight in a liberal supply o 
with frequent supplies of weak liquid 
manure. After growth is completed they should have a long dry at 
throughout the winter months, or they fail to bloom satisfactorily. The 
Mexican and Cattleya house temperature is the most suitable foe C. cristata, 
4 indeed it is for most of the genus; for instance C. Sanderiana, C. 
his is there- 
water during the growing season,
