THE ORCHID REVIEW. 151 
had the effect of causing the foliage of Odontoglossum crispum to become 
very much bronzed. This will dono harm ; in fact, it is generally a good sign 
that the plants are healthy, and likely to do well. The damping down of the 
houses should now be done three times daily, and it should be done well, 
a good supply of water always being at hand for this purpose. For damp- 
ing, hard water can be used, the soft being stored for watering purposes. 
There are several cool-growing species that will be in a good condition 
for repotting this month. Among them are more of the Odontoglossum 
crispum type that have bloomed and are starting to grow. Then there are 
many of the cool-growing Oncidinmee:4 in a fit condition, such as O. macran- 
thum, O. tigrinum, O. i O. ck ph , O. varicosum, 
O. Forbesii, O. crispum, and any others that are starting ‘to grow. The 
usual peat and sphagnum moss cannot be beaten for a compost, and the 
potting should be done firmly. 
Then there are some of the small growing kinds of Masdevallia that may 
be repotted. This genus delights to grow in the coolest possible house 
during summer, but during winter the temperature should be a little higher ; 
in fact, the Intermediate house is not too high. Too much damp and cold 
is the cause of the leaves dropping off or becoming spotted with black 
marks. The pretty little white autumn flowering species, M. tovarensis, 
should now be attended to, and repotted if necessary, and also any of the 
others having passed out of bloom. Masdevallias of the more showy type, 
such as M. Harryana, M. ignea, and M. Veitchiana, will now be making a 
brilliant show in this department, intermixed with the Odontoglossums, 
Oncidiums, Epidendrum vitellinum, and other cool species that are in 
flower. No fire should now be wanted. 
Tue INTERMEDIATE HovusE.—Temperature: Day, with sun heat, 75° ; 
without sun, 65° to 70°; night, 65°; morning, 60° to 65°. Like the pre- 
ceding, this department will now require well shading from the hot sun, in 
order to keep down the temperature, and to be kept very moist by damping 
down frequently. Although air cannot be applied here in such large volume, 
yet a little should always be kept on if possible, and no favourable oppor- 
tunity for increasing this amount should be allowed to pass by. In short, 
try to keep the above temperatures with as much air as possible. No heat 
from the hot water pipes should now be required here, unless it is occa- 
sionally of an evening, when it is cold or a frost is expected, when a little 
warmth would be very beneficial. Several things in this department will 
also require repotting—such, for instance, as the Odontoglossums of the 
grande type, some of the Miltonias and Oncidiums, Cymbidiums and 
Lycastes, Adas and the Chimera section of Masdevallia, which should 
never be grown cooler than this. Trichosma suavis and Maxillarias should 
also be repotted, and other species which may be found to grow best here ;
