10 THE ORCHID REVIEW. [APRIL, 1903. 
young growths will soon follow, and should any plant require top dressing 
or more pot room, do not delay either operation, or the young roots will 
get damaged, however carefully the operation be performed. In repotting 
the plants do not disturb or injure the old roots if possible, keep the plants 
well elevated above the rim of the pot, and use a few neat sticks to hold all 
securely. The compost suitable will consist of equal proportions of fibrous 
peat, leaf soil, and chopped moss. Give plenty of drainage, and pot 
moderately firmly. 7 
The following plants may also now be safely top-dressed, or repotted where 
necessary : Cattleya Percivaliana, C. Lueddemanniana (speciosissima), C. 
Leopoldi, C. amethystoglossa, C. Gaskelliana, and the autumn-flowering 
‘C.labiata. After giving fresh material, keep them well shaded, and apply 
water sparingly until re-established. C. Lueddemanniana, which remains 
in the Warm house the whole year, should be grown in pans and suspended 
near the glass, where it can obtain the maximum of light and heat. Give 
water copiously when growing freely, but only a limited supply is necessary 
‘when at rest. These remarks are also applicable to C. superba. C. 
Schilleriana should be given little water until the sheath becomes apparent. 
The present is a good time to repot such species as Lissochilus, and the 
deciduous Eulophias, using pots well drained, with a compost of fibrous 
loam, leaf-mould, and coarse silver sand, with an addition of fine clean 
broken crocks. Place the plants in a sunny position in the Mexican house, 
and when in full growth copious supplies of water may be given. When 
resting the plants should be treated like Habenarias. 
The pretty Trichopilia suavis is now producing its flower spikes, and all 
the species of this genus grow best in a shady position in the Cattleya or 
Intermediate house, and if treated like Cattleyas will keep free from spot, 
which often takes hold of them when kept too wet or cold. Cattleya 
citrina has its flowers well advanced, and may now be given water more 
freely. After flowering it should be placed in ashady position in the Cool 
house, and water given sufficient to keep the pseudobulbs plump. 
Keep the night temperatures generally as previously advised, but if the 
weather be mild a slight increase may be allowed. 
THE AMATEUR’S COLLECTION. 
‘WE were speaking last month of the advantages of purchasing imported 
plants, and it may be added that many forms of flowers which would 
not do for exhibition purposes are really much more useful when the 
object is the decoration of the room or person. Take, for instance, the 
ever popular Odontoglossum crispum, ordinary forms of which lend 
themselves to decorative purposes more readily than the highly-prized 
forms with round massive flowers, because lighter in effect—a great element
