204 THE ORCHID REVIEW. ' [JuLy, 1910. 
removed at once as soon as they are seen. They are very easy to sponge 
off when in a young state, but if allowed to attain the age of a few days it 
requires the aid of a brush or piece of stick to dislodge them, so firmly do 
they hold, and it takes treble the time to remove them. 
CATASETUMS, with the allied genera Cycnoches and Mormodes, are now 
growing strongly in the warmest division, and copious supplies of water are 
now necessary for them to make good bulbs. When the new growth is 
about half made up, alternate waterings with weak liquid cow manure will 
be beneficial to them. Keep a sharp watch for the small yellow thrip, 
which is very harmful to the young leaves. 
COMPARETTIAS.—At the warm end of the Intermediate house, C. 
coccinea, with its pretty yellowish red flowers, and C. falcata, with its dark 
crimson flowers, will soon be in flower, and should have copious supplies of 
water until the flowering season is past. At the cool end of the house C. 
macroplectron will be a little later, but requires the same treatment, which 
is similar to that given to Burlingtonias. 
Disa.—Disa grandiflora, D. racemosa, D. x langleyensis and D. x 
Veitchii should be kept well syringed, and never be allowed to approach 
anything like dryness at the roots at this season. They should be kept in 
the coolest and shadiest place possible, and where free circulation of air can 
be given them, if anything like success in cultivating them is aimed at. 
Frequent fumigation with XL. All compound will keep the yellow thrip 
away, which is a frequent cause of ill health in this particular class of 
plant. Keep them clean and cool, and then you have a good chance of 
growing Disas, which are very difficult subjects to grow satisfactorily. They 
are among the showiest of Orchids when well grown. 
EpIcaTTLEYAs.—The generic hybrids, Epicattleya matutina and E.-c. 
radiato-Bowringiana, should be grown in a temperature of 60° to 65°. 
They are now rooting freely, and should have a light position, with plenty 
of moisture around them. The compost should be kept moist, but not too 
wet. They are easy to manage, providing that they are not subjected 
to a sudden drop in the temperature, which will quickly cause spot to 
appear on the foliage, making the plants look unsightly, and also causing 
many leaves to drop off. 
EULOPHIELLAS.—The handsome Eulophiella Elizabethz will now be 
pushing its young growths, and if requiring repotting should be attended 
to. It will do well in Osmunda fibre and sphagnum moss, well mixed 
together, or in peat and sphagnum, half of each. Pot moderately firmly, 
and allow them plenty of room in the receptacle for two or three years’ 
growth, for with judicious watering the compost will keep sweet, and they 
do better when not disturbed too often. After repotting, water carefully 
till they are well rooted. They should be placed at the warm end of the
