348 THE ORCHID REVIEW. 
always occupy the warmest part of the house, and be suspended just so far 
from the glass that the cold from the same does not strike down upon them. 
Avoid, also, cold draughts, and water during winter very carefully. Under 
such treatment they should grow well, and keep free from that tiresome 
spot. They are soon laid low when attacked by spot, which I think is 
generally caused by a check brought about by too low a temperature, 
especially if they are at the same time wet. 
Schomburgkias grow very successfully with Mexican Orchids during 
summer, but will not withstand so much cold during winter as many of 
that order. I have known the Mexican short-bulbed Lelias take no harm 
when the thermometer has fallen almost to freezing point for a short time 
when the atmosphere has been very dry. But I am far from advocating 
such a low temperature, for I have never seen their coudition improved 
thereby. A well balanced intermediate temperature should be the aim, but 
if this cannot be relied upon Schomburgkias should certainly be removed 
to a warmer house. Lelia superbiens produces its spike in summer, but 
does not flower until the following early spring, when the spike will have 
reached six or seven feet in length. Calanthes should now have much less 
water, enough only to support the flower spikes, which are now getting 
well advanced. The intermediate Aérides crispum and its varieties, also 
A. Fieldingii, require but little water during winter, and delight in the 
same house as the Cattleyas. 
CYPRIPEDIUM KIMBALLIANUM. 
The facts relating to this plant and the other species of its section having 
been fully stated, it will be neither profitable nor edifying to the readers of 
the Orchid Review to traverse the remarks on the subject in the issue for 
October last. The chief question affects the first Cypripedium Kimball- 
ianum, respecting which I asked for reference to its publication as a 
species. By this I meant a description entitling it to the consideration 
of the botanist. The fact that the writer refers to the enumeration of the 
name only in catalogues and lists of garden plants, explains his _treat- 
ment of the subject, namely, to embody in his note all the material 
necessary to make it complete for the Orchid growers and amateurs 
who so largely patronise the Orchid Review. In this he was doubtless 
right, and I readily withdraw any remarks, which he may consider 
unpleasant, although nothing was further from my mind than to give offence. 
JAMES O’BRIEN. 
[We are much obliged for Mr. O’Brien’s note. Our object in calling 
attention to the matter was to rectify a series of perfectly unnecessary 
blunders, and we certainly thought that the remarks now happily with- 
drawn were unmerited. When an Orchid has been mentioned in five
