THE ORCHID REVIEW. 25 
Cymbidium grandiflorum and C. Tracyanum, the former in bloom, and 
filling the house with its fragrance, and the latter developing its spike. 
These have been growing in a very cool house with C. Lowianum up till the 
beginning of December, but were then given a little more warmth and light 
to develop their blooms. __ It is not everyone that considers C. Lowianum a 
cool Orchid, but the success attained here through growing it cool warrants 
me in terming it one of the best cool Orchids we have. The treatment 
followed here will be described in due course. 
It is impossible to say a word about all the different Orchids in the Cool 
houses, so we will pass on to the Intermediate department, where are placed 
the Lycastes, a deserving class of plants not much grown just now. L. 
Skinneri is now pushing up its flower spikes, yet should still be kept 
moderately dry ; also L. plana, now in bloom. The deciduous kinds, such 
as L. cochleata, consobrina, aromatica, &c., and the strong growing L. 
lanipes, Barringtoniz and mesochlena, must be kept quite dry, except when 
showing signs of shrivelling, when a little water should be given. The 
same remarks apply to the Anguloas. Sobralias should never be kept dry 
for long at a time, and if the drainage is in good condition water should be 
given when the surface becomes dry. Miltonia vexillaria at this season is 
an intermediate subject, and being in full growth, requires very careful 
management, fluctuations of temperature, an over saturated atmosphere, 
and insufficient ventilation, being the chief things to guard against. Here, 
again, harm would result if we attempted to keep the old moss alive, the 
surface appearing dry, whilst immediately beneath the compost is quite 
moist. Small plants will naturally take water more frequently without 
taking harm than plants in large pots. The plants should be looked over 
frequently, as the edges of the inner young leaves adhere to each other, and 
these should be released with the aid of the thin part of a budding knife 
handle. If there is any suspicion of thrips being present, give a slight 
fumigation with Richards’ XL.All, and sponge the leaves with clean tepid 
rain water to remove dust and dirt. Another good intermediate Orchid is 
Odontoglossum citrosmum, which is here grown in baskets suspended from 
the roof. They have now finished growing, as far as last season’s growth 
is concerned, and should be kept very dry to induce the formation of flower 
spikes in the succeeding growths, that are just now beginning to show them- 
selves. The plants will not suffer even if the bulbs shrivel, as they soon 
plump up again when given a good watering, and this may be done 
immediately after the appearance of the flower spikes. 
Numerous members of the large and ever increasing ‘‘ slipper” family 
find existence more congenial in an intermediate temperature, such, for 
instance, as our old friend C. insigne, which will grow in almost any 
temperature, but best in the one stated above. This species always has
