THE ORCHID REVIEW. 
[JULV, IV2I. 
-where they grow abundantly on the small branches of stunted oaks, with 
very little, if any, foliage. They are exposed to the direct rays of the sun 
and other elements at all seasons. The larger and better specimens, how- 
ever, are found in more favourable localities in the dense shade of the forest, 
usually bordering, or within the influence of, the rivers and streams. The 
temperature at this altitude ranges from 60 to 80 degrees, but during the 
rains rising about ten degrees higher. During the winter it is very much 
less, even hoar-frost is not absent. The rainfall on these hills may be roughly 
estimated at 200 inches annually, and, in consequence, the atmosphere is 
somewhat humid, yet there is an abundance of sunshine owing to the 
absence of fog and mist, which are common to the Himalayas only. The 
result is no stagnation of the air, and the branches of the trees, having no 
moss or lichen on them, remain dry nearly all day. Though the annual 
rainfall is so high, yet within not more than a radius of twenty miles the 
greatest rainfall in the world is recorded annually at Cherripoonjee, viz., 
5-600 inches, or as much as 30 inches during 24 hours, and at an altitude ot 
about 4,000 feet. 
Having noted the conditions under which Vanda ccerulea grows in its 
native habitat, I have cultivated them at Barrackpore very successfully, 
though the temperature is higher and the atmospheric conditions different. 
There is no reason why these plants should not thrive in just as hardy a 
style in any of the tropical countries where the conditions are somewhat 
similar. The secret of 
growing Vanda ccerulea is 
plenty of sunshine at a 
temperature not exceeding 
100 degrees, with a certain 
amount of humidity, which 
may be established by 
placing a layer of sphagnum 
much rain as the plants can 
get, and a good resting 
season after flowering, say 
from September to Febru¬ 
ary, when the plants are 
naturally dormant. They 
may also be grown in shade 
if other conditions are favourable. This mode of cultivation would not 
apply to England or America, where, owing to the severity of the weather, 
treatment under glass is necessary. 
It is questionable whether the plants of Vanda coerulea from the Khasia
