212 THE ORCHID REVIEW. (JULY, 1912. 
and as much light as it is possible to afford them without scorching the 
young foliage. Both species are now rooting freely and making considerable 
progress with their new growth in the warmest house. They require to be 
examined every day, so that the best rooted plants, and those which are 
pushing up flower spikes, may be supplied with water whenever they require 
it. Water should not be allowed to lodge in the centres of the young 
growths, and the whole plant should be carefully examined from time to 
time for insect pests. 
Pualus.—The different sorts of Phaius, species and hybrids, may at this 
season be repotted if they are in need of it. They will root well, and grow 
satisfactorily in the compost as advised for Calanthes, and they may be 
potted in the same manner. During their season of growth a decidedly 
moist atmosphere should be maintained by damping between the pots and 
stages several times daily. Should the points of the leaves become black, 
more air should be given, and the amount of moisture should be reduced. 
TRICHOPILIAS.—T. suavis, and its lovely variety alba, also T. Back- 
houseana, T. marginata, and several others, will now be forming new 
growths, and when these are about to push roots is the best time to do any 
repotting. They are best grown in the Intermediate or Cattleya house, 
suspended from the roof, where they can be shaded from the sun. They 
will succeed in the same compost as Odontoglossums, grown in baskets or 
shallow pans, and it is always advisable to be careful in the matter of 
watering, as, should they get an over supply, it is liable to cause the 
pseudobulbs to become badly spotted, which frequently means the loss of 
the plant. Care should be taken with the whole of this genus that the 
roots are kept in a sweet and healthy condition, therefore, if the compost is 
at all decayed it should be renewed at the proper period. These Orchids 
are not grown as much as their beauty deserves. 
TuHuNIAS, by this time, will have finished blooming, and should be 
removed to a sunny and airy house, and any that have not bloomed may 
have the apex of the growths pulled out. They must have water whenever 
they require it, and an occasional watering with weak liquid manure will be 
beneficial. They should be syringed on bright days to prevent attacks of 
red spider, which is very partial to them at this season, and they should on 
no account be put away to take care of themselves. As soon as the whole 
of the leaves fall away water can be entirely withheld. 
PHAL&Nopsis.—Plants which were repotted early in the season will by 
now be well established and rooting freely in the new compost, therefore 
they may have an increased supply of moisture at the roots, but care must 
be taken that it is not overdone. Every inducement should be given the 
plants to make their growths quickly, and, at the same time, that growth 
must be consolidated as it is made. The house should be ventilated freely,
