244 THE ORCHID REVIEW. [AucusT, 1912. 
treatment. Owing to the large quantity of water these plants require when 
in full growth, they are best repotted every season, and, therefore, the plants 
must be placed in moderate-sized pans. 
CoCHLIODAS AND THEIR HYBRIDS.—Plants of Cochlioda Neetzliana, C. 
vulcanica, and C. sanguinea may also be repotted in the same kind of 
compost as that used for Miltonia vexillaria. A light position in the 
Odontoglossum house will suit them at all seasons. These plants, when 
crossed with the different Odontoglossums, have given us the beautiful 
Odontiodas, and those who saw the effect of these delightful Orchids in the 
various groups at the recent International Exhibition may well ask the 
question, What will they eventually become? Although of such recent 
introduction there are many varieties, and they all thrive under the same 
conditions as the parents. The plants are rather erratic in their time of 
growing and flowering, and, therefore, whenever it is seen that the new 
growth is about to push new roots, it is advisable to repot the plant, if it 
requires it. As these plants have very fine wiry roots, the compost should 
be used in a finer condition than generally given to thick-rooted plants. It 
should be pressed firmly into the pots, and the plants must not be allowed 
to suffer for want of water at any time. Small pots or pans should only be 
used, as over-potting is most detrimental, the plants being unable to push 
through a thick body of compost. 
TRICHOPILIAS, sometimes called Pilumnas, are a most beautiful and 
easily-grown family of Orchids. TT. nobilis and T. fragrans are two 
charming autumn-flowering Orchids which may be purchased cheaply, and 
are easily procurable. They flower profusely, and the flowers are very 
fragrant, and have lasting qualities when cut. They succeed and grow 
freely in a cool Intermediate house, suspended close to the roof, and are 
best accommodated in half pots, which should be well drained. They will 
also do well in the same compost as Miltonia vexillaria. They should 
receive copious supplies of water during their season of growth, but when 
the growths are developed and matured only sufficient moisture to keep the 
pseudobulbs plump and the roots in a sound healthy condition is necessary, 
T. suavis, T. marginata, T. Backhouseana, and any others that have 
flowered, and are pushing new growths, may be repotted, should it be 
necessary, whenever the young growths are about to push new roots. 
PLEIONES.—In the Cattleya house the Pleiones will now be completing 
their new growths, and, therefore, will need more light and ventilation. 
Give them sufficient water to keep the compost moist, there being no 
necessity to dry them to induce them to flower. The cool-growing varieties, 
as P. humilis and P. Hookeriana, will require liberal and frequent 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.
