198 THE ORCHID REVIEW. 
come under this category. Nearly all the summer and autumn 
Cattleyas thrive infinitely better under the vines when they get the 
ammonia from the vine border, and the abundant syringing and air the 
vines enjoy in spring, while the summer and autumn airiness and drying, 
when the grapes ripen, consolidate their growth and encourage flowering. 
Cattleya Warscewiczii (gigas), Cattleya Dowiana aurea, Cattleya labiata, 
Lelia anceps (in the coolest place), Odontoglossum grande, Odontoglossum 
Insleayi, Oncidium Jonesianum, Vanda cerulea, Vanda Roxburghii, 
Vanda Denisoniana, Dendrobium nobile, Lelia autumnalis, all have done 
well, and many of them very exceptionally well in a warm Muscat house. 
They should be near the lower ventilators, where they are placed over saucers 
of water, and in the full draught of the ventilators, which are constantly open 
in fine weather. It is curious to see how the roots of Vanda ccerulea push 
out just where they get most air, provided there is water underneath the 
basket they are in. 
All these Orchids I have mentioned thrive in this house from March till 
November, when the vines are pruned and the chrysanthemums are brought 
in. The amount of cold air and moisture needed by the chrysanthemums 
makes it then necessary to put these Orchids into the Mexican house, 
where the temperature is between 50° and 60° as a rule. Any house, 
however, that is sufficiently warm and airy will suffice for winter if it be not 
a north aspect, and I venture to think that those who care to follow out the 
lines of treatment I have suggested for the above-named Orchids will not 
repent taking my experience as a guide. 
ORCHIDS AT CAMBERWELL. 
Among a large number of interesting Orchids seen in flower the other 
day in the collection of R. I. Measures, Esq., Cambridge Lodge, Camber- 
well, we noted a fine plant of Cypripedium Sanderianum bearing a spike of 
three flowers, the petals measuring 19} inches long; also several good C. 
Rothschildianum and other species and hybrids. In the Masdevallia house 
M. Harryana and its allies made a brave show, bearing hundreds of their 
brilliantly-coloured flowers. Mr. Chapman’s method of treatment was 
detailed at page 105 of our last volume, and it is satisfactory to record its — 
success, as we have heard it said that these plants do not thrive in smoky 
localities. During last winter’s frost the temperature was often lower than. 
usual, sometimes below 40°, but this was attended with no bad results, the 
plants being kept rather dry. Among many other species in flower, we 
noted the remarkable Pleurothallis Roezlii, and a fair proportion of the 
usual showy species which flower at this season. The collection was fully | 
described in our last volume. : Cues :
