with rose coloured spots. The spur is short and is generally more deeply coloured 
than the sepals and petals. It is a native of the mountains of Sylhet and Nepal 
in Northern India and grows at an elevation above sea level ranging from about 
4000 to 7000 feet. 
The rainfall per annum is as follows:— 
January inch May 45- 50 inches September 35-40 inches 
February 23 inches June 95-100 ,, October 17-22 , 
March 8- 9 ,, July 100-105 .; November 2-5 ,, 
April 25-30 ,, August 80- 85 ,, December about $ inch 
The temperature range is as follows, the figures given being the lowest mean and 
the maximum registrations for the particular months:— 
Jan. (Winter) 41-67" May §4-80° Sept. (Autumn) 64-77° 
February 44-71° June (Summer) 63-77° October 57-76" 
March (Spring) 47-75° July 63-82" Nov. (Winter) 46-70° 
April §0-81° August 63-78 | December 43-70° 
The plants grow high up on tall trees and they receive shade from the foliage of 
their harbouring tree during the greater part of the day, but in the early morning 
they often have the direct rays of the sun. 
It is apparent, therefore, that in Brisbane and places further north, cool bushhouse 
treatment is necessary, particularly in the Summer months. In those parts of 
Brisbane where the Winter: temperature falls below about 40 degrees it will be 
desirable to get it under cover of glass for the midwinter period, and, in places 
south of Brisbane, for probably the whole of the Winter months. If attempts are 
made to grow it in North Queensland the coolest possible part of the bushhouse 
must be used for it, except, of course, on the higher tablelands. 
Watering should be practically eliminated during the Winter, should commence 
gradually with Spring, be profuse in Summer, and then slacken off in the Autumn 
until the circle is complete. Even in Winter time, however, sufficient water should 
be given to prevent the shrivelling of the leaves. 
AERIDES ODORATUM 
This is probably the best known and most generally grown species of the genus. It 
is of a wide distribution, being found in India, Sikkim, Assam, Siam, Burma, China 
and Cochin-China. It is a hardy species with leaves about seven to nine inches 
long, strap-shaped, recurved and dark green in colour. The racemes are long and 
pendulous. The flowers are numerous and of good size. Sepals and petals creamy 
white, deepening in colour with age, tipped with purple. The lip is three-lobed 
and somewhat richer in colour. The spur is conical and incurved. 
As will be realised from its wide range of distribution, it is a very adaptable species 
and will thrive under very varying conditions. It is amenable to ordinary bush- 
house treatment in Brisbane and northwards, but requires slightly warmer treat- 
ment in the South. Little water is desirable in the colder months, but during the 
Summer plentiful supplies can be given.
