January, 1922.] THE ORCHID REVIEW. 17 
CyPRIPEDIUMS.—This very useful section of winter-flowering Orchids has 
been giving a very bright display, and will continue doing so for some time 
yet. When they pass out of flower, any that require repotting should be 
attended to this month, especially those of the insigne section, and their 
hybrids. A suitable compost for these consists of equal parts fibrous loam, 
osmunda fibre, and sphagnum moss, with the addition of crushed crocks and 
coarse silver sand. Mix all thoroughly together, and before using see that 
it is fairly moist and warm to the hand. Select pots of suitable size, and 
in the case of large plants pans will be preferable ; crock them according to 
the amount of root room the plant requires, and work the compost firmly 
with the potting stick.amongst the roots. When potted, the plants should 
be given a warm, moist position, and but little water will be required for 
some time, beyond frequent light spraying overhead. 
Mexican La&iias.—These beautiful species with their hybrids are useful 
subjects to grow for flower at this time of the year. Yet they often prove 
very disappointing in the neighbourhood of large towns owing to the 
visitation of fogs. In rural districts, where one is free from this sooty 
atmosphere, they area source of satisfaction to all who see them. The 
past summer has been one to their liking, and at the present time their 
beautiful arching spikes of white and coloured flowers are commencing to 
unfold. Where a house is not set apart for them, a warm end of the 
Cattleya house will suit them, providing they get plenty of light and air in 
the growing season. Lelia autumnalis and L. Gouldiana have just passed 
the flowering stage, and should now be kept on the dry side, with only 
sufficient water to keep the pseudobulbs from unduly shrivelling. 
CALANTHES.—C. Veitchi, C. Harrisii, C. William Murray, and C. Bryan 
continue to give a useful display of bloom. Very little water will now be 
necessary after the spikes are fully developed. When the spikes 
have finished flowering, the bulbs may be turned out of the pots, the 
compost shaken off, and then stored in shallow boxes placed on a shelf in the 
intermediate house, where they may remain until the time of repotting 
comes in March. 
CyPRIPEDIUMS.—These comprise another useful class of Orchid for 
flowering at. this period of the year, and one, I am pleased to say, that is 
becoming very popular. Their flowers last a considerable time, and are 
always admired for their decorative qualities. With the various species and 
hybrids, flowers may be had from November until May. Many plants are 
now developing their spikes, and consequently should not be allowed to get 
dry; a little extra moisture at this time will be beneficial. Given a 
position in the intermediate house, they are easily grown and enjoy a 
compost of fibrous loam with some dry cow manure and a sprinkling of 
crushed crocks.
