AERIDES QUINQUEVULNERUM 
This species has proved somewhat of a difficult subject in the past, as after a year 
or two it loses its leaves and dies. Plant somewhat like odoratum in appearance, 
but is distinguishable by the habit of its leaves in clasping the stem of the plant. 
Flowers also resemble those of odoratwm but are distinguishable by five reddish- 
crimson blotches on the sepals and petals, from which it gets its name. Lip is 
funnel-shaped, and the spur is green in colour and conical in shape. The flowers 
are sweetly perfumed, their scent resembling that of ‘‘Lily-of-the-Valley.” 
It is a native of Mindanao (Philippine Islands), Sumatra, Borneo and Timor, in all 
of which islands it grows upon tall trees on the interior ranges at a height above 
sea level ranging from 4000 feet to 6000 feet. The climatic conditions in each 
of these islands are somewhat similar, i.e., on the coastline the temperature 
never falls below 69° to 70° nor rises above 90° to 95°. At the elevation at which 
their native growth takes place the mean average range of temperature would be 
from approximately 57° to 78°. 
The rainfall varies considerably. In Timor it reaches fourteen inches in February, 
and falls to about half-an-inch in Midsummer; in Mindanao the rainfall is not so 
diverse, as the minimum average rainfall for any month is August 2 inches, while 
the maximum falls occur in October and November, when about 8 inches are 
averaged. In Borneo again the rainfall is fairly heavy throughout the year, the 
lowest average rainfall being in April, when 5 inches is the mean, in May, June 
and July, the dry season, about 7 inches is the average, while from September to 
February the rainfall ranges from 11 to 20 inches. 
It would seem that the best treatment for this species is to grow it in a glass- 
house close to the roof—preferably suspended over a fish pond where the evapor- 
ation will keep the plant moist. In the South hothouse conditions will be necessary, 
particularly in the Winter months.

AERIDES VANDARUM 
This species resembles Vanda teres in appearance of the plant, but is slenderer 
in form. It bears two to three large blooms on short spikes. Sepals and petals pure 
white. Lip three-lobed with erect sides. The spur is long and straight. This plant 
grows well on a board or raft or in a shallow basket. It is a native of Coimbatore 
in the Nilgiri Hills, Southern India, where it grows on the trees in the humid and 
shady forests on the mountain slopes. 
Throughout the year the temperature never falls below 70° and rises throughout 
the Summer months to 90° to 92°, while in Winter the maximum temperature is 
generally about 84° to 86. Rainfall is fairly constant throughout the year, 
though in Winter time it is not so copious, as it falls to about two to three 
inches per month, whereas the Summer rainfall ranges from six to nine inches. 
It is obvious that this plant will require warm, shaded and moist treatment.
