The system has the advantage of sidestepping all rules of priority for 
hybrids, and is equivalent to a universally recognisable ‘‘ vernacular” 
name for each hybrid, while at the same time the hybrid retains its 
commemorative or other name (if it has one) for use on all occasions of 
solemn botanical pomp and ceremony. : T. L. MEAD.

CALENDAR OF OPERATIONS FOR JANUARY. | 
le; “Ee Yo 
HE advent of a new year brings its renewed cycle of cultural routine, 
and both the enthusiastic amateur and the professional grower will 
be making the necessary preparations. Things are abnormal at present, 
owing to the existing world strife, but we may hope for an early return to 
peaceful conditions, which, I am convinced, will give a great impetus to all 
phases of horticulture, and bring many accessions to the ranks of Orchid 
culture. An enormous change has taken place in the popularity of Orchids 
during the last quarter of a century, as the pages of the Orchid Review 
can testify, and new accessions to the cult are always welcomed, for it is 
from such beginnings that our largest collections of to-day have developed. 
The Review has contributed largely to this growing popularity, both in 
stimulating experiment and in recording so thoroughly the course of events. 
Its influence. has always been on the side of progress. This little 
appreciation from an old reader is, I hope, permissible on the Review com- 
mencing its twenty-fifth volume. May its influence continue to increase. 
For the benefit of new readers, amateurs and beginners in Orchid 
culture in particular, I will give the most suitable temperatures for the 
different departments. They are as follows :— 
Cool house: Day, 50° to 55°; with sun, 60°; night, 50°. 
Intermediate house: Day, 60° to 65°; with sun, 66° ; night, 57° to 60°. 
Cattleya and Mexican house: Day, 60° to 65°; with sun, 68° ; 
night, 58°. 
East Indian house: day, 65° to 70° ; with sun, 75° ; night, 65°. 
These figures are only given as a guide, as no harm will accrue from 
slight variations either way, but severe fluctuations may be the means of 
much harm. 
In large establishments there are often houses that are kept at 
temperatures a little higher, or lower than the figures given, hence the
