BULBOPHYLLUM MACROBULBUM (BALFOURIANUM).—Knowing that the 
pages of the Orchid Review are open to help amateurs, I should like to have 
some information as to the flowering of Bulbophyllum Balfourianum. In 
1915 I obtained a part of the plant shewn by Messrs. Sanders at the Royal 
Horticultural Society, but have not succeeded in flowering it as yet. It has 
made a good growth every year with enormous bulbs, and it is now making 
a new one, with a leaf 244 inches long and 4{ inch broad. Last spring I 
took off the original bulbs and potted them up, and from them I obtained a 
new growth last year. They are now making a second growth. There is no 
doubt that the plants grow well with me, if only I could get them to flower.

WHEN cultivating Orchids for Mr. E. V. Low at Vale Bridge, Haywards 
Heath, there was a fine plant of Bulbophyllum Balfourianum which had 
not flowered for several years, so it was dried carefully until the bulbs showed 
signs of being in need of water. Soon afterwards the plant recommenced 
activity, and water was applied, at first sparingly, and then in increased 
quantities as the new growth made headway. On the completion of the 
bulb a flower spike was produced. I am convinced that all Orchids require 
a period of rest under drier conditions, and the rather severe ripening that 
the above plant thereby received no doubt lead to the following bulb being 
sufficiently vigorous to yield a flower spike. —FRED. GREENFIELD, Hay- 
wards Heath. 
BuLBopHyLLUM BALFOURIANUM grows well in the Rosslyn collection at 
Stamford Hill, London, N. It is kept in the Cypripedium house, where the 
temperature in winter is maintained at 65° at night and 70° during the day, 
With a corresponding increase in summer. The plant receives an abundance 
of moisture, and is never allowed to remain dry long enough for the sphag- 
num moss to be killed. No difficulty is experienced in flowering it. In June, 
I9Ig, it produced three spikes with an aggregate of fourteen flowers, and 
‘was awarded “Cultural Commendation ”’ when exhibited at the R.H.S. 
‘One year it flowered twice.—F. W. THURGOOD.
