series of years. The plants succeed best when grown close up to the roof 
glass, where they are free from drip, and out of the way of the syringe, and 
a warm, moist atmosphere is necessary to their well being. During the 
growing season they must have liberal supplies of water at the root, but 
during the winter, when they are at rest, much less will suffice, although 
they must not be allowed to suffer for the want of it even then. Watering 
overhead is not to be recommended, and, in most cases, is decidedly 
harmful. The most suitable time for repotting these plants is soon after 
the plants have passed out of flower, but disturbance at the roots should 
not take place unless the condition of the compost and drainage make this 
necessary. For compost use a mixture similar to that advised above, but a 
little more loam fibre may be added. 
CATTLEYAS and L&iias.—The flowers of these most beautiful Orchids 
may now be enjoyed the whole year round, and among the late spring and 
early summer-flowering species and hybrids are some of the most lovely 
kinds imaginable. Plants that have flowered and have since enjoyed a 
short period of rest, will now be showing signs of activity, either by making 
fresh roots or growths. The condition of these plants at the roots should 
be ascertained, and if any are in need of fresh rooting material it should be 
supplied to them before the new roots and growths get very far advanced, 
thus avoiding injury to either. The method of repotting this class of plants 
has been explained in previous numbers, and there is no need to repeat it, — 
and the same remarks apply also to compost for them. The whole of this 
family should be potted moderately firmly, as when this is done the compost 
lasts much longer, and the water passes through much better than it does 
when they are potted loosely. Latesummer and autumn-flowering Cattleyas 
are now growing freely, and some are forming their pseudobulbs, and must 
have liberal treatment. The majority of these plants produce their flower 
spikes before the season’s growths are completed, therefore they should not 
be allowed to suffer for want of water at the roots until the newly-made 
pseudobulbs are fully developed. Newly-potted plants require careful 
watering, only just sufficient water to keep the new materials in a moist 
condition being necessary. 
LEPTOTES BICOLOR.—At the present time the plants of this ne terete- 
leaved species are making fresh roots, and repotting may be done, if necessary. 
It succeeds suspended in the Cattleya house, and is best grown in shallow 
pans, in the same kind of compost as Cattleyas, and the plants should be 
potted quite firmly. During active growth the plants must have liberal 
supplies of water, but when growth is completed the amount should be 
gradually reduced, and during the resting season only sufficient to keep the 
plant from shrivelling should be given. 
CATASETUMS and CycnocHEs thoroughly enjoy the warmth of the sun,
