“OCItOBER, 1916.| THE ORCHID REVIEW. 247 
roots. I do not advocate, however, placing them in positions out of sight, 
as the old adage, out of sight, out of mind, is often too true. 
DEcIDUOUS CALANTHES.—These most useful winter-flowering Orchids 
are now showing their flower spikes from the base of the newly-made 
pseudobulbs. The plants should be afforded ample space, and receive as 
much light as possible, with water at the roots whenever they become dry. 
The late-flowering varieties of the C. Regnieri section, with others that 
produce their flowers at the same season, are fast making up their pseudo- 
bulbs, and still need abundance of water at the roots, with an occasional 
watering with liquid manure. The temperature of the house should not be 
allowed to fall below 65° at night, until the flowers are expanded, when they 
may be placed in a house a few degrees lower, where the flowers will last 
considerably longer than if left in a high temperature. 
CATTLEYAS AND ALLIES.—Any plants of this large family may still be 
repotted, provided they are making new roots, the precautions advised 
from time to time respecting the application of water to the compost being 
strictly observed. 
OncipIuMs.— In the Cool house several species of these interesting and 
useful plants are developing their flower spikes and preparing to bloom, 
and they will open their flowers much better if removed to the coolest end of 
the Intermediate house, the slightly warmer conditions being a great 
assistance to them. In order to prevent the plants from suffering it is 
advisable to remove the flower scapes when the flowers are all open, as it 
is very exhausting if they are allowed to remain too long upon the plants. 
MiLTon1as.—Miltonia spectabilis and its varieties Moreliana and 
atrorubens, with M. Clowesii and M. Regnellii, are interesting members of 
this genus, which produce their flowers during late summer and early 
autumn. When their flowering period is over, and the pseudobulbs have 
finished growing, the supply of water at the roots should be gradually 
reduced, and the rooting material kept on the dry side until growth 
commences again in the spring. M. Roezlii, and its variety alba, with any 
of the late-flowering plants of M. vexillaria or its hybrids, may still be 
repotted, should they require it, and the new growths are in the desired 
condition. M. Roezlii requires slightly warmer conditions than M. 
vexillaria, and all should now be placed in their winter quarters at the 
warm end of the Intermediate house, and watered only when necessary. 
VaNnpas.—The end of October is the best time of the year to overhaul 
Vandas of the V. tricolor and suavis section, as at this season the plants 
produce roots in abundance, and continue to do so throughout the winter 
months. The pots in which they are grown must be well drained, and 
clean, living sphagnum moss is the best material to pot them in. Those 
that are not in need of new material may be surfaced with living moss,
