306 THE ORCHID REVIEW. 
typical C. insigne. It is said to differ chiefly from C. x Arthurianum typied 
in having some dark crimson spots on the dorsal sepal. Our illustration) 
from a photograph kindly sent by Mr. G. I’Anson, of Upper Clapton, 
will be observed that the dorsal sepal is not nearly so much spotted asin 
some of the published figures, yet the present one is an absolute fac simil, 
being done by photographic process throughout. We hope to be able 
examine this point at the coming flowering period.

CULTURE OF VANDA AMESIANA AND V. 
KIMBALLIANA. 
ON several occasions we have found these two beautiful Vandas cultivated 
in the East Indian house, and it may therefore interest some of our readers 
to know that they succeed far better under cool treatment. In Mess 
Hugh Low and Co’s. establishment, at Upper Clapton, may be seen a large 
batch, in the most robust health, which have received no fire heat since the 
end of March last. In fact, they are grown like cool Odontoglots, exceft 
that less shading is necessary. ‘They are now throwing up flower-spikes ® 
profusion. If the weather is cold at this period a very little heat ae 
advantage, enabling them to mature the buds, but in mild weather this i 
unnecessary. Vanda ccerulea is grown with them, and with great succes 
Many growers complain that this plant will not succeed for many a 
together, but in the majority of cases it is because too much heat iss 
In the Shan Hills these three species grow, together with Luisia Amesiat’s 
at from 4,000 to 5,000 feet elevation, in a comparatively cool climate, yes 
the ground is sometimes white with hoar frost. Again, in the Khasia 
Vanda ccerulea grows and flowers profusely, at 5,000 feet altitude, ot 
much as eight or ten degrees of frost occasionally occur in the month 
January. Too much heat is simply a drain on the constitution of the 
plants, and is not only unnecessary, but injurious, and therefore worst i 
useless. Those who have not been satisfied with their success under ¥ 
treatment should not hesitate to move them to cooler quarters, at leas 
part of their plants, and the remainder would probably soon follow: ‘ 
let no one hesitate to include them in their collections becaus¢ they Be 
not a warm house, for they are naturally cool Orchids. We are led to m 
these remarks because we have never met with healthier of etter-g™ 
plants than the ones above mentioned.
