B4 THE ORCHID REVIEW. Marcu, 1922. 
compost used is made up of equal parts chopped osmunda fibre and 
sphagnum moss, mixed with plenty of sand and finely broken crocks. Pots 
or pans will answer most purposes. First place in them a few crocks, then 
some of the rougher material over them, so that the plants to be potted may 
be easily accommodated. Potting should be done rather firmly, keeping 
the base of the new lead slightly below the rim of the pot. Sufficient water 
should be given to prevent the pseudo-bulbs from shrivelling, but no more, 
until root action is well- extended, when the supply of water may be 
gradually increased until well into midsummer. After this date, if satis- 
factory growth is being made, the plants and surroundings should be well 
supplied with moisture. 
SEEDLINGS.—Where the raising of seedling Dendrobiums, Cattleyas, 
and Leliocattleyas is carried on, there will be a good many plants in need of 
repotting, and these must now receive attention at once, and be put right 
for growing, so that they may enjoy the full advantage of a long season of 
activity. Keep them growing in comparatively small pots, but give them 
fresh material if possible. They are at all times best if kept well up to the 
light, but not too much exposed to the direct rays of the sun, or damage 
may be done to these small plants that will not be overcome. 
The larger plants of Leliocattleyas and Cattleya hybrids which have 
‘produced flowers during the autumn and winter months, and are showing 
signs of renewed growth, will also require attention. Use suitable pots to 
accommodate them for at least a couple of years, with a compost of equal 
parts of osmunda and Ar fibre. See that the plants are potted firmly and 
‘watered carefully until new roots begin to grow freely. 
HaABENARIAS.—These pretty, tuberous Orchids have been resting on 4 
-shelf near the glass in the warm house since flowering, and will soon push 
new growth from the apex of the tubers. They succeed better if potted 
annually, using pans of suitable size with a compost of good fibrous peat, 
loam, and sphagnum moss, in equal proportions, adding finely broken 
_crocks and coarse silversand. Mix these well together, and pot the tubers 
moderately firm. When repotted, water with a fine rose water-pot and 
place them on the shady side of a warm house, and as near the glass as 
convenient. Whilst in growth, a sharp watch must be kept for thrips, and 
-the usual remedies applied, or the foliage will soon be disfigured and give 
the plants an unsightly appearance. 
PLATYCLINIS.—These species form some of the most graceful of spring- 
flowering Orchids, and are to be commended on account of their easy 
culture. P. glumacea is probably the best known, but all the species 
. delight in similar treatment, and will thrive in the warm or Cattleya house. 
They are best grown in well drained pans in a compost of finely chopped 
-Osmunda fibre and sphagnum moss, and should be potted as they begin t0
