very little room to grow in, and when well flowered makes a good show 
with its numerous scarlet flowers. It can be grown in the Cattleya house 
or Intermediate house, and does best suspended from the roof. Shallow 
pans suit it to grow in, or if specimens are wanted baskets will suit it. 
When mixed with other flowering Orchids they make a beautiful show, and 
will stand a considerable time in flower, and are not generally affected by 
fogs. They should be potted as soon as they have finished flowering, as 
they root from the new bulb. A compost similar to that advised for 
Bulbophyllums will suit them, and they should not be allowed to shrivel for 
want of water at any time. Give a little extra shade until they get 
established again, when they can be given Cattleya house treatment. 
They like to be placed in an airy position near the ventilators during the 
summer months. 
RODRIGUEZIA FRAGRANS, as its name denotes, is a very fragrant species, 
and the graceful spikes are much admired. It should be suspended from 
the roof, and is very free-growing, and likes plenty of room to ramble about 
in. A nice pan or basket will give a good many spikes, as most of the 
bulbs will throw two spikes. Scale is about its only enemy, and this can 
be kept down by occasional sponging with water and soft soap. Inter- 
mediate house treatment suits it during the summer months, but it should 
be removed to slightly warmer quarters during the winter. They should 
be repotted as soon as they commence to root, and placed in the stove until 
the roots get well into the new compost. Osmunda fibre, leaves and very 
little moss and crocks will make a good compost for it. Crock the pans 
well, as it likes plenty of water in the growing season, but not a sour 
compost to root into. 
ONCIDIUM CONCOLOR, for its size, and the small amount of room it takes 
up, is one of the most showy Oncidiums grown. It will now be in flower 
or just about to flower, and makes a beautiful show as a front row plant for 
a group, as its yellow flowers form a good contrast to the more brilliant 
Cattleyas. It is very little trouble to grow, and takes up very little room, 
_as it can be suspended from the roof of the Cool or Intermediate house. It 
should be repotted or top-dressed as soon as it commences to grow, and a 
compost of Osmunda fibre, leaves, moss and crocks will suit it. Give 
plenty of water during its growing season, and keep it fairly dry after it 
has made up its bulbs, until the spikes show, when plenty of water must 
again be given until the flowers are developed ; then if kept fairly dry the 
blooms will last a long time in perfection. Like most Oncidiums, it likes 
plenty of air during the summer months, and a fair amount of sunshine in 
the autumn to ripen the bulbs, which helps to prevent the appearance of 
spot during the dull weather. 
Now that we are again in the growing season, every advantage should
