306 THE ORCHID REVIEW. 
The influence of P. Rothschildianum is unmistakable on this occasion, 
while the modified shape and the spotting on the lip are as clearly traceable 
to P. bellatulum. The photograph was taken exact size, but it is probable 
that the flowers will become larger when the plant becomes stronger, when 
also the hybrid may be expected to show the racemose character of 
P. Rothschildianum. It is a very interesting hybrid. 
CALENDAR OF OPERATIONS FOR OCTOBER.

Tuts month is, I always think, a most enjoyable one to the Orchidist. His 
labour of the past half year now becomes apparent. It is his harvest, so 
to speak, and the better and the more judiciously he has worked, so also 
will be the results attained. The plants should now have completely over- 
come the momentary checks caused by divisions, repotting, &c., and be 
well provided with vigorous new roots, and in order to make one cheerful 
he has only to note day by day—and it is impossible for a lover of Orchids 
not to do so—the effect of all this upon his plants. Even on those species 
that have finished up their pseudobulbs for a considerable time, and are now 
more or less ripened up, new roots will still bristie and thread their way, 
making as it were a tufted mat on the surface of the fresh new compost; 
whilst those new pseudobulbs that are now forming, or have recently done 
so, will be observed to broaden and fill up rapidly, assuming proportions 
second to none of their ancestors in size and substance. These are signs 
of past good work and of present healthy conditions. 
The following table of temperatures may now be of some assistance as 
a guide, but it need not be too strictly adhered to. One must be guided 
principally by the reigning conditions of the weather and allow a rise or fall 
of from 5° to 10° as the elements dictate. 
CooL OR ODONTOGLOssuM HovusE:—Day, 60°, night, 55°, morning, 
50°. Fire heat here during the night will now again be pretty frequently 
needed, and also during the daytime should the weather be very cold and 
dull. It is best to have a gentle warmth in the pipes, if only for a few hours, 
so that reasonable ventilation may still go on. Much harm will be done to 
Odontoglossums if fire heat is employed excessively—they will not stand it. 
Have enough only to maintain a steady and regular temperature of from 
50° to 60° with ventilation. This will be found to be by far the best 
temperature throughout the winter months. Odontoglossums grow none 
the better, but rather worse, if subjected to a very low winter temperature. 
Those among them having made up their bulbs should be given a rest by 
keeping them much dryer than others in full growth. Do not, howevel 
dry to excess any that are in the midst of growth. Moderation with this
