RESTING ORCHIDS 45 
easy to do much mischief by subjecting them to a too 
prolonged and rigorous resting time. Seedling Orchids, 
as a rule, require little or no resting season until after their 
first flowering, and Cattleyas, Lzliocattleyas, and other 
evergreen hybrids require a rather shorter period of rest 
than deciduous species. 
Bulbophyllums, Cirrhopetalums, and many other small- 
growing Orchids are frequently killed by attempting to give 
them a dry resting season, although there is a section which 
lose their leaves in winter like the deciduous Dendrobiums, 
and these are benefited by being dried off in a cooler house 
when the leaves fall, keeping them dry until growth starts 
again, in the same manner as Dendrobium nobile, D. War- 
dianum, D, crassinode, and other deciduous Dendrobiums. 
The evergreen Dendrobiums of the D. densiflorum and 
D. Farmeri class require a short rest in a lower tempera- 
ture, and should be watered a little occasionally, especially 
if they show a tendency to shrivel, which is not a good 
thing for any Orchid. 
Aérides, Vandas, and Saccolabiums require a lower 
temperature in winter, and less water. Many of these begin 
to grow in March; after that season they require heat and 
moisture more liberally. 
As a rule, the plants themselves give the best indication 
when the resting season has arrived, and, in the case of 
those which lose their leaves, they show how much rest is 
necessary. The starting of the new growth indicates when 
growing conditions should be restored. In respect to the 
very small-growing species, and especially evergreen kinds, 
it is much better to ignore the resting season rather than 
to lower the vitality of the plants by a severe drying off.
