308 THE ORCHID REVIEW. 
CYPRIPEDIUM x MAUDIZA. 
WE have received from Messrs. Charlesworth & Co., Heaton, Bradford, 
a flower of a most beautiful hybrid, which received a First-class Certificate 
from the Manchester Orchid Society on September 27th, under the above 
name. It wasraised by them from C. Lawrenceanum Hyeanum crossed 
with the pollen of C. callosum Sanderz, and is about as intermediate 
between them as could possibly be. It is interesting to note that there is no 
trace of reversion, the plant being as true an albino as either parent. The 
dorsal sepal is very broad and rounded; the colour white closely veined 
with bright green. The petals are somewhat falcate, light green, with 
darker veins, and a few darker warts on the upper margins; and the lip 
is light green. The scape is also light green. Messrs. Charlesworth say 
that it has an exceedingly good constitution, and they must be congratu- 
lated on their success in raising it. 
CALENDAR OF OPERATIONS FOR OCTOBER. 
By H. A. BurBeERRy, Orchid Specialist, King’s Heath, Birmingham. 
THE temperature for the present month should read as follows :-— 
Coo. Hovuse.—Day, with sun, 60° to 65°; without sun, 55° to 60° ; 
night and morning, 50° to 55°. 
INTERMEDIATE House.—Day, with sun, 70° to 75°; without sun, 
60° to 65°; night and morning, 55° to 60°. 
Warm or East Inpian Housr.—Day, with sun, 75° to 80°; without 
sun, 70°; night and morning, 60° to 65°. 
The weather during September was all that could possibly be desired— 
in fact, it proved to be the best growing month throughout the summer 
and the partly formed growths have gone forward very rapidly, thus counter- 
balancing the retarding effects of the dull weather experienced earlier in the 
year. 
The present month must see the new growths properly ripened of 
consolidated, which takes place naturally if less moisture is distributed, and 
as much air admitted in each department as the condition of the outside 
weather will allow. The value of air at this season for all species is great: 
For Cool Orchids one can scarcely have too much, whilst for Warm and 
Intermediate kinds under rather than over ventilating is to be feared. O 
iter it is possible to over-do a good thing, but with ordinary care the 
latter is not likely to occur this month. 
In speaking of air and ventilation, I may again point out the great 
differences between the various structures in which Orchids are grow? 
Some are lofty, in which the circulation is free and rapid, and generally @
