kept drier, and slightly cooler, which will prolong the flowering period and 
make the house more accessible and enjoyable to thase visiting them. The 
potting of the plants, as they pass out of flower and begin to push roots at 
the base of the pseudobulbs, should have attention whenever necessary, 
taking care not to overwater the new compost until new roots have entered 
it freely. 
SOPHRONITIS GRANDIFLORA.—This miniature Cattleya thrives in the 
Cool house, and now that the plants are commencing to push new roots- 
from the growths which recently flowered, they should have new rooting 
material given them, if they are in need of it. The Cattleya compost will 
answer their requirements, but it is obvious that these small plants will 
require it cut up into much smaller pieces, and small receptacles must be 
used for their accommodation. 
Cympipiums include some of the most useful and easily-cultivated 
Orchids, both species :and»many most beautiful hybrids, and, as their 
flowers last a considerable time in perfection, they will undoubtedly receive 
extended popularity. Being plants which resent root disturbance they 
should not be potted until really necessary, as the plants bloom more 
freely and produce finer flowers when the pots are well filled with roots. 
Any plants that have not sufficient room to develop the season’s growth, or 
of which the compost has become decomposed, should, of course, be 
repotted. The pots should be well drained, and a larger shift may be given: 
than to most Orchids. A compost in which good yellow loam fibre, with 
some fine broken crocks to keep the whole open, sbould be used. The best 
time to repot is whenever the half-made pseudobulbs are about to produce 
roots. Extreme caution is necessary in the application of water to the 
newly-potted plants, until the roots have freely entered the new compost ; 
an excess in many cases not only means the loss of leaves, but also decay 
of the pseudobulbs. They grow best in a shady position in a Cool inter- 
mediate house, with plenty of fresh air, and they resent strong sunshine at 
any time. 
PHAL&NopsiIs.—P. Schilleriana, Aphrodite, amabilis, and Sanderiana, 
having passed out of flower and commenced to make new leaves and roots, 
should be afforded new rooting material, if they require it. Whatever 
receptacles the plants are grown in, they should be well drained, and only 
a thin layer of clean live sphagnum moss used as compost. They should 
be grown on the shady side of the East Indian, or warmest house. Care is 
necessary, even with these pseudobulbless plants, in the application of 
water after root disturbance. 
Lycastes.—L. Skinneri and its varieties that are starting into growth 
should be repotted, if necessary, also other varieties of the same genus. 
These plants succeed in a similar compost to that used for the green-leaved
