colours—white or cream, with cross-bars of reddish-purple. Flowers appear in 
the early Autumn, and last for 6 to 7 weeks. 
This orchid is found between 5500 feet and 6800 feet on the Tenasserim Moun- 
tains, in the far South of Burma, in the Isthmus of Kra. This area has a tropical 
monsoonal climate with an exceptionally heavy annual rainfall, the heaviest part 
of which falls in the Autumn. Even in the driest months of the year (the end 
of the Winter) rainfall does not fall below 3 inches, while the coastal tempera- 
tures are high and humid throughout the year, seldom falling as low as 60° on the 
coldest night of midwinter. The range at the elevation at which Cymbidium tig- 
rinum grows is comparatively cool, ranging between 42° minimum and 77° 
maximum. 
This orchid will stand ordinary bushhouse treatment in Brisbane, and can be 
grown out of doors in a sheltered position. Where the temperature falls below 40° 
it should be moved under glass as the Winter approaches. Water must be applied 
copiously throughout the Summer, and the compost must be kept reasonably damp 
even in the Winter. 
CYMBIDIUM TRACEYANUM. Burma. 
. A very handsome species resembling grandiflorum in manner of growth. The 
flowers are up to six inches in width. The sepals and petals vary from yellowish- 
green to brownish-green with lines of dots and streaks of crimson or red running 
lengthwise, the petals being narrower than the sepals. The lip is prominent, and 
has three lobes, the side lobes being broad, fringed at the edge, crisped and re- 
flexed. It is creamy coloured, richly marked with reddish bars and dots. The 
column is greenish, and it also has reddish spots. 
The treatment suggested for giganteum, etc., will serve this fine species well. 
CYMBIDIUM ZALESKIANUM. Native of Sikkim. 
A natural hybrid btween giganteum and grandiflorum which combines the best 
features of both parents. Variety Kalawensis is particularly fine, though rare. 
The habit of the plant resembles that of both parents—strong, large pseudobulbs 
and long, tough, sword-shaped leaves. The flowers are about six inches across, with 
yellow sepals and petals with a large sulphur-yellow lip, covered with fine golden 
hairs, brilliantly marked with crimson and with two toothy crimson plates on the 
disk. 
It is said to be rather a difficult subject, but I am growing it under the shade of 
a tree in my yard, and it is making steady growth, although it has not yet 
flowered.
