TI THE ORCHID REVIEW. [May, 1918, 
Although the/plants.may appear to be growing strongly, care should be 
exercised in watering, as an excess at this stage may be the cause of much 
harm. C. Triane, C. Schroedere, with many hybrid Cattleyas, Lalié- 
cattleyas, Brassocattleyas, and allied subjects, that have recently passed out 
of flower, may have attention as regards repotting whenever they commence 
to make new-roots.. Any plants of C. Mossie and Mendelii which have 
failed to produce flower sheaths may be repotted when they -are about to 
push new roots. Those which have deteriorated through loss of toots or 
or other causes, will also begin to make fresh roots at this season, and may 
be repotted into small receptacles and started afresh. The pots should be 
well drained, and a well-cleaned compost of Ar fibre will answer the 
requirements of the plants. 
SOPHRONITIS GRANDIFLORA and its hybrids may be treated in precisely 
the same manner as Cattleyas when fresh rooting materials are required, 
but, owing to their dwarfer nature, must be placed in smaller receptacles, 
and the potting materials pulled into much smaller pieces. | 
ODONTOGLOssuMs.—Plants of O. Rossii, Cervantesii, Humeanum, 
(Erstedii, and other Mexican Odontoglossums, that have recently passed 
out of flower, will now require a rest, and should be suspended close to the 
roof glass, and be afforded only sufficient water to prevent the pseudobulbs 
and leaves from shrivelling. An excess of water whilst the plants are at 
rest will cause the roots to decay. It is difficult to determine the amount 
of rest each plant requires, but they will resume growth, each in its propet 
season, and then each plant requires individual attention. The Columbian 
Odontoglossums will now be blooming freely. a 
PHALENOPSIS.—Although not grown at the present day to the sam 
extent as formerly, Phalzenopsis are most desirable Orchids, and require 4 
shady position in the warmest house. After flowering, they should be 
induced to take a short rest, but must not be allowed to suffer for the want 
of moisture, either in the atmosphere or at the roots. When they commence 
to make new leaves and roots is the proper season to afford new rooting 
material. 
DENDROBIUM PHALzNopsis will by this have commenced to grow, and 
will quickly push new roots from the base of the new shoots, therefore 
before these roots make much progress, any necessary repotting should be 
taken in hand. These plants should be placed in the smallest receptacles 
possible, and be afforded a light position in the warmest house. They w 
also succeed grown suspended in a Croton stove. In repotting any of this 
section of Dendrobiums the material should be placed quite firmly around 
the base of the plants. Other Dendrobiums that require similar attention 
at this season are the tall growing D. Dalhousieanum, moschatu™ 
fimbriatum, clavatum, &c. | ; og
