158 THE ORCHID REVIEW. _ [Juty-Aveusr, 19:38, 
MiLToniA BLeEvuANA, and other hybrids in which M. Roezlii is one 
parent, enjoy slightly more heat than M. vexillaria, therefore are best grown 
in the warmest part of the house, or in a house where a few degrees more 
heat is maintained. As regards other matters they succeed under the same 
conditions as M. vexillaria. 
TRICHOPILIAS comprise a beautiful and easily grown genus of Orchids. 
T. nobilis and T. fragrans are autumn-flowering species which produce 
their fragrant flowers in profusion at a season when flowers are acceptable. 
They succeed and grow freely in a cool Intermedtate house, suspended from 
the roof, and are best grown in half-pots, which must be well drained. They 
succeed in a similar compost to that used for Miltonia vexillaria. T. suavis, 
T. coccinea, T. Backhouseana, and others which have flowered, and are now 
pushing new growths, may now have any necessary repotting done. 
PLEIONES.—In the Cattleya house the Pleiones will now be completing 
their new growths, and will need more light and air to consolidate the 
bulbs. Sufficient water must be given to keep the compost moist. The 
cool-growing varieties, P. humilis and P. Hookeriana will require liberal 
supplies of water until their growths are completed. The position most 
suitable to them is one close to the roof ventilators of the Cool house. 
EPIPHRONITIS VEITCHII.—At the present time these plants are producing 
a number of aérial shoots from the flowering growths. Such growths — 
should now be taken from the parent plant and potted several together, 
when they will form nice little specimens. This, like Sophronitis, is a plant 
that many fail to grow satisfactorily, owing in many cases to receiving too 
much heat. It is best grown in shallow pans, and delights in a fairly moist 
position near the glass, with an even temperature the whole year round. 
ONcIDIUMs.—During the present period there are many of the cool 
Oncidiums that may require attention as regards repotting. The young 
growths should be some three or four inches in length, and about to push 
forth new roots, when this is attempted, as they suffer less at that stage 
than at any other. They should be placed in small receptacles, and a 
similar compost to that used for Odontoglossums, with slightly more broken 
leaves added, makes a satisfactory rooting medium for them. The warmer 
growing members of this large and varied group of plants may also have 
attention as regards repotting, should they require it, when they reach the 
desired condition. These plants revel in a hot humid temperature whilst 
making their growth, and afterwards a season of rest. The thick-leaved 
varieties are capable of standing a long, dry rest, and too much water at that 
Season causes the roots to decay, with the attendant loss of vigour. The 
cool-growing O. macranthum, and allied species that are in bloom, °F 
developing flower spikes, should have water supplied te them whenever they 
become dry. This section of the genus resents dryness at the roots or 1"
