26 THE ORCHID REVIEW. [JANUARY, 1913 
the magnificent group of Orchids (staged by Lt.-Col. Sir George L. 
Holford, K.C.V.O., Westonbirt (gr. Mr. Alexander), at the Royal Inter- 
national Horticultural Exhibition, Chelsea, last May, and which won the: 
King’s Cup. The flowers are very large, of excellent shape, and the colour 
a delicate pink, with a light yellow disc to the lip. This form was raised in 
the collection. The original form was raised by Messrs. James Veitch and 
Sons, Langley, and flowered for the first time in March, 1902, when it 
received a First-class Certificate from the R.H.S. under the name of 
Leliocattleya Digbyano-Schroedere (O.R., x. p. 117). The name was 
afterwards amended to Brassocattleya langleyensis (Orchid Stud-Book p. 45)- 
CALENDAR OF OPERATIONS FOR JANUARY. 
By J. T. Barker, The West Hill Gardens, Hessle, E. Yorks. 
TIME, with its chastening hand, again brings us to the opening of another 
year, and with it we see the commencement of the twenty-first volume of 
the Orchid Review. During the twenty years of its existence Orchidology 
has made immense strides, especially in the departments of the cultivator 
and the hybridist, and in this development the influence of the Review has. 
been a power for good. We cordially wish it increasing success in the days. 
to come. 
The work of the present month will consist chiefly in maintaining the 
proper temperatures, providing suitable atmospheric conditions in the 
houses, and the cleansing of the plants and the houses. The plants should 
be kept as quiet as possible, no attempt being made to unduly push them 
into growth, as this premature growth is never satisfactory, and in many 
cases damps off, and sets up decay of the rhizome. 
TEMPERATURES:—The most suitable temperatures for the different 
departments 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 houses: 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 if the temperatures are allowed to fluctuate 
widely serious damage may occur. 
VENTILATION.— The ventilation of the houses at this season must have: 
most careful attention at all times. They should be re-charged with pure 
air every day Ly some means, as a stagnant atmosphere is most injurious. 
The admission of fresh air to the houses does not, in many cases, get the 
attention it should have, and the observant grower will soon find the 
difference between a badly ventilated and a judiciously ventilated one. It
