THE ORCHID REVIEW. 131 
A flower of a curiously striped form of Cypripedium X Mrs. Canham is 
sent from the collection of H. J. Ross, Esq., of Florence. It is analagous 
with C. X Dauthieri Rossianum, whose history has already appeared in 
these pages (ii., p. 20). 
A curious flower of Cattleya Mendelii, having only two sepals, two petals, 
and a slender somewhat flattened column with the usual single anther, is 
sent from the collection of Joseph Broome, Esq., Sunny Hill, Llandudno. 
It is said to have shown the same deformity for several successive seasons. 
It apparently belongs to a batch of plants which has several times been 
mentioned in these pages (see p. 199 of our last volume), but we cannot 
suggest the cause. 
Flowers of the beautiful Dendrobium x Euterpe, to which an Award of 
Merit was given by the R. H. S. on March 28th last, are sent from the 
collection of Sir Trevor Lawrence, Bart., Burford, Dorking. 1t was 
derived from D. nobile ¢ x D. Wardianum 3, and thus must rank as a 
variety of D. X murrhiniacum, which according to the record was obtained 
from the reverse cross. Mr. White states that he sowed the seed in 1893, 
and some of the plants have now bulbs nearly four feet in length. 
WATERING ODONTOGLOSSUMS IN WINTER. 
As you have invited opinions on this subject, I venture to trouble you with 
my impressions. 
Knowing, as I do, O. crispum in its native habitat, the severe ordeal to 
which it is subject during frequent recurring droughts, I have no hesitation 
in saying that this plant under cultivation in Europe should be inured 
during the dark and gloomy winter months to comparatively dry treatment 
—a realisation, to a certain extent, of the conditions to which it is habituated 
in a state of nature. 
Subsequent to severe drought, the advent of the rainy season starts the 
plant into growth with spring-like vigour. 
Cultivators have it in their power to imitate to a considerable extent the 
conditions under which the plant is found in a wild state. Then, surely, 
the time best adapted to resort to dry treatment is during our winter 
months. 
Subsequently, under the influence of long, bright days combined with 
ample humidity, the plant flourishes under the most congenial conditions. 
Moreover, in a state of nature, periods of drought have a powerful influence 
on the early production of flowers. Thus there can be little doubt that on 
similar lines of treatment under cultivation the plant will be incited to early 
loom, : '  RoBeERT THOMSON.
