_ DECEMBER, I911.] THE ORCHID REVIEW. 359 
seems not unlikely that some interesting novelties remain to be introduced. 
We are glad to note that the author gives the station and altitude at which 
the species were found, as well as the localities and time of flowering, and 
these should be of great service in the event of the species being introduced 
to cultivation. Future parts of the work will be awaited with interest.

THE AMATEUR’S COLLECTION.

Coot House. 
THROUGHOUT this and the following months the requisite temperatures can 
only be maintained by the use of fire heat. The thermometer should not be 
allowed to descend below 45° Fahr., except in severe weather. It should 
register between 50° and 55° Fahr. during the day in sunny weather. Ifthe 
thermometer falls below the specified degree no water must be given to the 
plants until the correct temperature is again attained. During this and the 
following months the water used for direct application to the plants should 
be tepid. Damping-down on fine days should be done about 9 a.m. and 3 
p-m.; but only once, about mid-day, when the weather is dull and chilly. 
It is advisable to look over the stock of plants daily, and only give water to 
those growing plants which require it. Any in bud or flower will usually 
need water once a day; those in full growth, every alternate day, whilst for 
those at rest, once every week or ten days will be sufficient. 
As soon as the flower-spikes of Odontoglossums or Oncidiums attain 
the length of a few inches they should be tied to sticks, and a piece of cotton 
wool wrapped round their base, to prevent their being eaten by slugs. All 
resting plants should now be placed at the coolest end of the house, together 
with those in flower, whilst those in full growth should be grouped together 
at the warmest end. The late-flowering type of Odontoglossum grande is 
now in spike, and should be fed with weak liquid cow-manure twice a week. 
The house should now be gay with the winter-flowering Oncidiums, such 
as O. crispum, tigrinum, Forbesii, and varicosum, with various hybrid 
Odontoglossums and Cymbidium Tracyanum. At this season of the year it 
is unwise to attempt the re-potting of any Orchid, but now is a good time 
to prepare the various composts for later use. Any plant, however, may be 
top-dressed with a thin layer of sphagnum moss, providing that the roots are 
not disturbed in any way. The leaves of the plants should be sponged 
once a fortnight with pure tepid rain-water, and should fogs prevail the roof 
glass should be washed immediately after it has cleared away. 
CATTLEYA House. 
Most of the cultural remarks mentioned above are applicable to the 
inmates of this house, the only exception being that a higher temperature is 
required. The temperature should register between 60° and 65° Fahr. by
