NOVEMBER, 1909.] THE ORCHID REVIEW. os 
a plant which is never given a chance to become dry, and roots in Cattleyas 
mean healthy plants and fine flowers. The plants should be looked over 
occasionally for scale, which must be carefully sponged off or it will soon 
turn the bulbs and leaves yellow. If they are sprayed occasionally with 
insecticide it will prevent a lot of it, but the plants want looking over as 
well several times during the winter to keep them thoroughly clean. It is 
most important in Cattleya growing to keep them clean, and the glass 
should be washed whenever it gets at all dirty, both inside and out, to give 
them all the light possible during the winter months. The stages and 
surroundings should also be kept clean, as it helps to keep away woodlice, 
slugs, cockroaches, &c., which are great pests in a Cattleya house. 
L&LIOCATTLEYAS, &c.—The hybrids are not so difficult to manage as 
the species, being much more robust and not so fickle under general treat- 
‘ment. Where a number of these are grown, and some are active and others 
resting, they should be sorted out, and the growing plants placed at the 
warmest end of the house. These, of course, will need an ample supply of 
water until their growths are finished, while those which have made up their 
growths can be kept on the dry side until they commence to push up their 
buds, when the supply must be: incteased ‘slightly, or the flowers will not 
develop properly. With the numerous varieties which are now in cultiva- 
tion, flowers can be had all the year round if a careful selection is made. 
They are very fine for grouping, and much freer flowering than the species. 
The long-stemmed varieties are very useful for cutting, and there is an 
endless variety of colours amongst them. Like the species, these are 
subject to scale, and should be looked over occasionally to keep them clean 
and in perfect health. Amongst the hybrids no fixed rule can be given for 
potting, as they are growing and resting at all seasons. Plants should be 
potted only when the roots are active, and not overpotted at any time. A 
mixture of Osmunda fibre, with a few leaves mixed in, and plenty of crushed 
crocks, should be used. Pot firmly, keeping the plants just below the rim 
of the pot. ‘When plants are potted in the winter time they must be 
carefully watered, and if the compost is damp when used they will go for 
some time without watering, if they are syringed overhead on every 
favourable occasion, and this will keep the bulbs from shrivelling without 
souring the compost. Always stage newly-potted plants in a batch by 
themselves, andthen no mistakes occur in watering. 
VANDA C@RULEA.—As the plants: finish flowering they will do well 
staged with the warmer Dendrobes in the Cattleya house, where they may 
remain during the winter. They will need very little water during the 
winter, just enough to prevent the leaves from shrivelling will suffice. They 
are rather difficult plants to handle, and a suitable corner has to be found 
for them for successful culture. Frequently the most unlikely place is just
