ODONTOGLOSSUM LONDESBOROUGHIANUM. 
Some growers experience great difficulty in the cultivation of this fine 
species, but as it succeeds admirably with me, a few notes on the treatment 
adopted will no doubt prove acceptable to the readers of the OrcHID REVIEW. 
In 1881 my master purchased a single plant on a block with two bulbs, 
which had been imported but a short time. I took it off the block and 
potted it with two-inch pieces of charcoal, finishing off with a little sphagnum 
moss. In a very short time it began to improve. It is kept quite cool, 
about 45° F. in winter, and whenever the weather is mild I give air night 
and day. The result is that I have now six plants in the best of health, 
with three or four bulbs each, and they flower every year. Under the above 
treatment it is one of the best growers I know of, and very floriferous.

(It would be interesting to know the treatment as regards summer tem 
perature and shading, and what other plants are grown with it. It maybe 
that cool treatment is the secret of success, as with Epidendrum vitellinum 
and Cattleya citrina from the same country. Cultivators have been working 
in the dark, as the precise habitat has not been divulged. Messrs. Veitch 
recommends a maximum of sun-light and sun-heat, near the roof-glass of 
_ Cattleya house, apparently because it is said to grow on shelving rocks fully 
exposed to the sun, where the temperature rises to 120° F. by day. Messi 
Backhouse received it from the same region as O. citrosmum.—ED.]
