THE ORCHID REVIEW. 
and Jynthia Hills compare favourably with those from the Shan States. 
From my own observation I find those from the latter by far the better 
plants, being larger in size, with a greater profusion of flowers ; whereas, in 
the former, although the plants are smaller they are more robust, better 
travellers, and the inflorescence is of a more brilliant and lasting nature.- 
The characteristics of this Vanda, and the temperature in which it 
thrives, have all been recorded by such eminent botanists as Hooker and 
Roxburgh, and as there has been no geographical change since their visits, 
I can add but little to their observations, though I fail to understand why 
these authorities should have limited us to such meagre records of their 
observations. Perhaps it is that my own will'here fill the gaps and be of 
benefit to the cultivators of this particular Orchid. 
What impressed me most, as no reference to the fact has hitherto been 
recorded, was the distinction between the Vandas growing in the dense 
shady forests and those in the open on the stunted oaks, with little 
protection from the direct rays of the scorching sun. In the summer 
months, from March till June, at this altitude of 3,000 to 4,000 feet, the 
heat is very great, and yet these very same plants, similarly unprotected 
from the elements of winter are subject to frost, which though not so 
severe as at an equal altitude on the Himalayas, exists, nevertheless, in* 
more or less severity, and is a menace to these hardy, though somewhat 
sensitive plants. These drawbacks undoubtedly account for the robust 
nature of the Vandas situated in open positions, although they are smaller 
than those found in the dense and shady depths of the woods, where they do 1 
not confine themselves to the oaks alone. My own personal observations* 
induce me to believe that Vanda ccerulea is more at home in the thick and 
shady forests of Nartiung, for the plants are larger in every respect and 
produce finer panicles of bloom. 
I have observed Vanda coerulea growing on the trunks of trees with na 
less than 16 to 20 pairs of large, dark green, healthy leaves, as well as at 
the same time bearing at their base four to six smaller growths, and which, 
would, in the course of a few years, grow into large specimens clumps 1 
whereas I have seldom seen a plant of this species growing in the open on 
stunted oaks with more than six to eight pairs of leaves, and these of a very 
dull yellowish colour at the time of flowering, denoting the severe strain 
thus placed upon their constitution. It is very seldom, if ever, that 
adventitious growths are seen upon the latter class of plants. 
Nature appears to recognise the adverse circumstances these Vandas 
experience in their desolate position and compensates them with a greater 
degree of prolifity; the seedlings are much more numerous when exposure ot 
the parent plant occurs. Gomparatively, very few seedlings are observable 
in the shady localities, which pointsto the fact that it is the fully exposed
