114 THE ORCHID REVIEW. (APRIL, 1912. 
pass out of flower and are seen to be making new roots, they may be 
repotted, if the compost in which they are growing is exhausted, or the 
plant requires a larger receptacle. Those plants which flowered during the 
winter months should have attention as soon as it is observed that they are 
beginning to push new roots. C. Lawrenceana, pushing up its flower 
spikes, should be kept in a fairly dry position, and only given enough water 
to keep the compost moist, and prevent the bulbs from shrivelling. After 
the flowers have faded, and the plant is seen to be pushing roots, it may 
have attention. This plant, when at rest, requires a warm, light position. 
If placed in a humid, cold atmosphere, the leaves turn black, and the bulbs 
decay. The present is a good season to repot any seedlings of either of the 
above families, as they get nicely established before the hot weather is 
upon us. 
L4&LIA ANCEPS and its varieties that require repotting should be finished 
as soon as possible, as they require a long season of growth, and take some 
little time to re-establish themselves after being disturbed. 
DENDROBIUMS.—For some time past the members of this large family 
of Orchids have been a prominent feature in our houses. Many of the 
earliest plants to flower are now developing their new growths, which will 
produce new roots when they attain a few inches in height. This is the 
best season to supply fresh rooting material to any requiring it. They may 
be grown in either pots, pans, or baskets, according to their character, and 
a suitable compost ‘consists of equal portions of peat, polypodium and 
osmunda fibres, and sphagnum moss. The pots and pans must be well 
drained, and no water should be given until the new roots are seen to be 
pushing through the compost. The plants may be slightly sprayed over- 
head on bright days, but this must be done with discretion, as if the water 
is allowed to lodge in the young growth it will decay, which is a great 
check to the plant. 
CATASETUMS, CYCNOCHES, and MORMODES.—As soon as the young 
growths are seen to be pushing from the base of the pseudobulbs of any 
member of either of the above families they should be repotted. They are 
best done annually, and a suitable compost is the one used for Cattleyas. 
The pots must be well drained, and the plant potted moderately firmly, and 
the long, heavy pseudobulbs neatly tied to a stake to keep them secure. 
For some time after repotting no water will be required, providing the 
compost is moist when they are done, as should it become wet there is 
great danger of losing the young growths. The plants should be grown 
close to the glass in the warmest house, and when in active growth they 
require a liberal supply of water. The plants should be rested with the 
Dendrobiums, and only have sufficient water to prevent the pseudobulbs 
from shrivelling.
