them best for the summer months, and the house should be kept as cool as 
possible and well damped. The plants should be carefully watched for 
thrips, which are very partial to them. Green and yellow fly are also very 
fond of them, but if a mild fumigation is given about oncea week it will 
keep them clean. If once allowed to make headway they quickly disfigure 
the plants, and make them look very unsightly for a year or two afterwards. 
MILToniAs.—Miltonia vexillaria with its many varieties and hybrids 
are now making a good show, and as soon as they pass out of flower they 
should be kept drier at the roots until the young growths are well away. 
Frequent dampings between the pots will almost suffice until the young 
growths are rooted. When the young growths commence to push roots 
any plants that require it should be repotted, using a compost consisting of 
one-third each of Osmunda fibre, polypodium fibre and sphagnum moss, 
well mixed together and potting moderately firmly. 
Oncip1uMs.—O. macranthum and O. lamelligerum will now be nearing 
the end of their flowering period, and in course of a week or two after the 
flowers are off they will commence to push new roots from the base of the 
last-made bulb, when any requiring it may be repotted, using the same 
compost as recommended for Miltonias. Use pots large enough to last 
them two years. They are very strong rooting plants and require plenty of 
rooting space. I have always found it best not to flower them the first 
season after repotting, as the spikes are on the plants for such a long time 
that the plants must be thoroughly rooted to withstand the tremendous 
strain put upon them. 
- TuHuntas.—T. Marshalliana, T. Bensonz, and others, which were 
potted as advised, will now be expanding their flowers, and should have 
every encouragement. Their pots will now be filled with roots, and must 
not be allowed to get dry. Alternate waterings with liquid cow manure 
will be of great benefit to them, and help them greatly in their development 
at the present time. After flowering the plants should be removed to a 
house where they can have full sunlight and free ventilation given, to help 
them to mature their bulbs. A sharp watch must be kept for red spider 
and thrip. It is a good plan to syringe them once a week with a solution of 
good insecticide, and the plants should be laid upon their sides and the 
operation thoroughly done. 
VaNpDas.—Vanda teres and V. Hookeriana are now making a grand 
show, and while the flowers are on should be lightly shaded during the 
hottest part of the day, but afterwards they should have full sunlight and 
be syringed several times daily. V. tricolor, V.suavis, V. insignis, and 
others of this section of the genus, prefer a warm, shady and moist position. 
They are a beautiful and very interesting class, and not at all difficult to 
manage if the grower will study them a little.
