maculata in a tuft of Veronica, though their presence was not suspected till 
the spikes appeared. The seeds had evidently blown there from a plant 
near by, and the presence of the Veronica prevented the seedlings from 
being disturbed. In a similar way seedling Orchises have been found in 
tufts of Iris. We once tried to raise Cypripedium Calceolus from unques- 
tionably good seed, but without success. We should be obliged if any of 
our readers will forward us any of their experiences on the subject. There 
are many natural hybrids among hardy Orchids, and artificial ones are not 
outside the range of possibility. 
RESTING OF DENDROBES. 
THis is a very open question, where and how to rest Dendrobiums. I, with 
many’ others, used to consider it essential, in order to flower them well, to 
remove them from the growing houses and place them in such a structure 
as a vinery or peach house, where they had much air and sunshine. I have 
now changed my views, and consider that way now quite unnecessary to 
produce abundance of flower. On the principle of resting which we now 
adopt we get a better class of flowers, and the general well-being of the 
plant is preserved, besides giving strength and sustenance to the new growth 
previous to new roots being emitted. The majority of our bulbs are as 
plump after they have finished flowering as they were before. 
I believe the whole thing is centred in full development. It is often 
thought that when the new growth has attained its full length the time has 
come for ripening to start, but full development is not attained till some 
time later, and, when full development is attained, maturity soon follows 
without much artificial aid. Then the new bulb contains much substance, 
and can produce its flowers without feeling any great strain. 
The process we adopt is as follows:—From the middle of August we 
admit a little air from the side or top ventilators at night, never much. The 
time of shading is also very gradually reduced, scarcely altering the supply 
of’ water till the new bulbs assume a golden colour, when the water is 
gradually reduced, but we never withhold it long enough to cause any 
shrivelling of the bulbs. During November and early December we allow 
them to remain dry as long as-possible, and if they are properly matured 
they will go several days without harm, maintaining a minimum tempera- 
ture of 55° till the new year, by which time the buds will be pushing fast, 
when the temperature may be raised five degrees at night, and rather more 
water given. 
Many growers cannot devote a- house to Dendrobiums, but nearly as 
good results can be obtained by taking them to the Intermediate Orchid 
house when the growth has attained its length.
