MARCH, 1922.| THE ORCHID. REVIEW. 85 
grow. During active growth a plentiful supply of water should be given, 
but this should be reduced at other seasons. 
GENERAL REMARKS.—March is usually a very fickle month, but duriny, 
sunny weather an increase of temperature will be advantageous to the plants: 
generally, providing there is not an excess of fire-heat at the same time. 
Sometimes the sun will make its appearance suddenly during the early part 
of the day, when the hot-water pipes are already sufficiently heated- to 
maintain the proper degree of warmth, and it will then be better to shade 
rather than allow the temperature to become excessive, or to attempt to 
reduce the same by a superabundance of air. Ventilation by means of top 
lights is often accompanied by considerable risk during this and the follow- 
ing month, and if indulged in should be done most sparingly, otherwise the 
cold draughts resulting are the means of checking tender growth, and, 
again, the atmospheric moisture is too rapidly transformed. See that all 
shading is thoroughly overhauled-and put ready for use by the end of the 
month. 
ODONTOGLOSSUM SCINTILLANS.—At the meeting of the Manchester 
Orchid Society held on January 5th, an interesting plant of the Walton 
Grange variety of Odontoglossum scintillans was exhibited from the 
collection of Philip Smith, Esq., Haddon House, Ashton-on-Mersey, The 
leading bulb carried a spike of 16 flowers, with an additional flower on the 
apex of the same bulb, and a Cultural Certificate was awarded to Mr. E. W. 
Thompson, who had grown the plant to such a fine state of perfection. 
When one considers that this garden-raised hybrid is the result of crossing 
the Colombian O. Wilckeanum. with the Mexican O. Rossii, the flower 
spike is truly remarkable, for O. Rossii rarely produces more than two or 
three flowers on a spike, and even O. Wilckeanum (crispum X luteopur- 
pureum) would be considered well developed with a spike of a dozen flowers. 
In the photograph of this plant sent by Mr. Thompson, the characteristic 
spotting of O. Rossii is recorded, the sepals being evenly spotted over 
their whole area, while the petals are only spotted on the ceutral area 
of their inner half. This plant evidently possesses a good constitution, 
for the flowers had been open two months before the photograph was 
taken. 
R.H.S. Awarps.—When the recommendation of any award has been 
proposed and put to the vote of the Orchid Committee, it will not be 
considered to have been “carried ” unless the number of votes cast in its 
favour shall be at least double the number recorded against it. When a 
Challenge Cup is won by an amateur, his gardener’s services shall, in 
future, be rewarded by the bestowal of an appropriate medal.
