OCTOBER, 1912.] THE ORCHID REVIEW. 393 
plants as soon as they are observed to be pushing up, and on the strongest 
plants as soon as all the flowers are open. 
VanpbAs.—In the Cattleya house such plants as V. Kimballiana. and V. 
Watsonii are developing their flower spikes, and should have water applied 
to them until the flowers are open sufficient to keep the sphagnum in a 
growing condition, but after the flower spikes are cut, or faded, very little 
water is needed to keep their terete leaves plump. V. tricolor, V. suavis, 
and others of this section which have lost some of their lower leaves, may 
be repotted at this season, when they soon recover from the ordeal and 
quickly re-establish themselves. 
CyMBIDIUMS.—Strong healthy plants of Cymbidium Tracyanum, C. 
Lowianum, C. insigne, and many hybrids that are now showing flower 
spikes should have plenty of water at the roet, others which are not yet 
showing should be kept rather dry for some little time longer, otherwise 
growth will commence and the plants fail to bloom. 
CYPRIPEDIUMS will now be pushing up their flower spikes, and these 
should be neatly tied up to small green stakes of suitable lengths, as advised 
last month. C. superbiens (Veitchii), as it passes out of bloom, should be 
repotted, should this be necessary. This plant succeeds best grown in the 
Cattleya house in a partially shaded. position, potted in a compost as 
advised for other tessellated-leaved Cypripediums. 
Disas.—The tuberous roots of these most attractive terrestrial Orchids 
are best repotted at this season, just as the new growths push up from the 
sides of the old flower spikes. The pots must be well drained, using a 
compost of equal portions of fibrous peat, osmunda fibre, and sphagnum 
moss, with a fair sprinkling of half-decayed leaves and coarse silver sand, 
or, better still, powdered sand stone, all mixed thoroughly well together. 
After repotting, one watering should be given to settle the compost around 
them, and then for some time spraying once or twice a day, or even more, 
according to the outside conditions, will suffice to keep them moist. The 
house in which they are growing must be freely ventilated, with only 
sufficient heat to keep frost away from them in cold weather. They delight 
in a cool, moist airy position at all times. 
MILTONIAS.—Miltonia spectabilis and its varieties Moreliana and 
atrorubens, with M. Clowesii and M. Regnellii, are interesting members of 
this genus for flowering during late summer and early autumn. After the 
plants have bloomed, and the pseudobulbs have finished growing, the 
supply of moisture at the roots should be gradually reduced, and the 
rooting material kept on the dry side until growth becomes again active in 
the new year. M. Roezlii, and its variety alba, with any late-flowering 
plants of M. vexillaria, or its hybrids, may still be repotted, should. they 
require it, when the new growths are in a desirable condition. The whole
