156 THE ORCHID REVIEW. [May, Igt1. 
staked up, and if possible a house devoted entirely to them where the 
-atmosphere can be kept a little drier, and the temperature a little cooler, 
which will be the means of the flowers lasting much longer, and more 
-comfortable to those who wish to see them. Push on with the potting of 
those which have passed out of flower, and are in the state that requires it. 
I always try to keep C. Schroeder, C. Mendelii, and C. Mossiz in a house 
-a few degrees lower than the hybrids, as I find the latter will stand a higher 
temperature, and-be the better for it. 
DENDROBIUMS.—D. Phalznopsis Schroeederianum will now be pushing 
forth its new growth rapidly, and any that require it should be repanned or 
repotted. The best receptacles for this class of plant are shallow pans, 
which can be suspended. The warmest house suits them best, very little 
-shade being necessary, and this only during the hottest part of the day. 
The compost recommended for Dendrobiums last month will suit them 
-admirably. D. formosum will also succeed under the same conditions, and 
~where the plants have commenced to grow, and are pushing forth new roots, 
‘they may also be repanned. D. infundibulum and D. Jamesianum will 
‘succeed grown in the same way in a cool intermediate temperature instead 
-of a warm one, and when well grown they are most beautiful and useful. 
Epidendrum vitellinum is now pushing up its flower spikes, and must 
not be allowed to suffer for want of water. Before the spikes get very far 
advanced the plants should be thoroughly cleaned. This class of plant 
mixed with the Cattleya family when in flower gives an additional charm. 
Anguloas and Lycastes which have passed out of lower may now be re- 
potted, if they require it, using the compost recommended for the green- 
leaved Cypripediums. A shady place in a cool Intermediate house is the 
proper place for these plants. 
CyYMBIDIUMS that require repotting may now be done. Such species as 
C. eburneum, Lowianum, grandiflorum (Hookerianum), Tracyanum, 
giganteum, and any of their varieties and hybrids, which have passed 
out of flower, and are on the point of making new roots from the young 
growths, may be done at this season. The compost I recommend is equal 
parts fibrous peat and loam, with a fair quantity of sphagnum moss and 
coarse silver sand. It should be used rather rough, and the plants should 
be potted moderately firmly, and much like an ordinary plant. After 
repotting great attention must be given in applying water, as over-watering 
at this stage means absolute ruin, one good watering after the plant has 
been repotted will suffice for some time. They will thrive in a cool part of 
the Intermediate house, where they can be shaded from direct sunshine. 
ONCIDIUM MACRANTHUM and its allies, when throwing up spikes or 
opening their flowers, should have attention in training the spike in the 
“way it is required, either fan-shaped or round stakes; it makes no difference
