January, 1918.] THE ORCHID REVIEW. 15 
variety validum has attained the height of two or three inches they 
commence to push forth new roots, and if repotting is contemplated this is 
a suitable time to undertake the operation. They succeed in a similar 
compost to Cypripediums, and should be repotted in the same manner. 
They delight in a fairly humid position in the Intermediate or Cattleya 
house, and the delicate grass-like flower-spikes of D. glumaceum make it an 
acceptable ornament to our houses. 
OponToGLossuMs.—Plants of this genus will be in all stages of growth. 
Many will be pushing up their flower spikes, and the latter should have 
every attention as regards staking, to prevent them from becoming a prey 
to slugs and other pests, which readily devour them. Plants of O. 
Edwardii, or any of its hybrids which have recently bloomed and are 
starting well into growth, should be attended to if repotting is necessary. 
If such plants are well established, having sufficient space to develop, and 
the material in good condition, they may stand over to another season with 
safety. All Odontoglossums delight in a good free drainage, and will 
succeed in two parts Ar fibre to one of sphagnum moss. Any plants, either 
species or hybrids, with growths which are some two or three inches in 
height and are about to push new roots, may be repotted if the compost is 
decomposed or the plant is in need of more root room. These early-potted 
plants, when the compost becomes settled and the moss commences to 
grow, form suitable seed-beds to sow seeds upon of almost all cool-growing 
Orchids. The seeds should be sown thinly over the surface, and be kept 
moist at all times. Extreme care should be taken in the application of 
water to the seed beds, as there is great danger of washing the seeds 
away. It is best applied with a very fine sprayer. When the young 
seedlings make their appearance, they should be removed to a light and 
airy position to prevent them from damping off. This is a simple and easy 
method for those who are anxious to raise seedlings for the first time, and 
experience and practice will teach them what are the requirements of the 
young plants. 
CALANTHES which have produced their flowers should be rested as 
advised last month, until they start to grow in the spring. 
GENERAL REMARKS.—The busy season is fast approaching, and a little 
forethought will save much time at a later period. A stock of potting and 
other materials should be obtained, so that when the potting season is upon 
us there is no delay for the want of materials. Neglect in potting Orchids 
does not pay in the long run, as a half-starved plant takes much longer to 
re-establish itself than a healthy one. The cleansing of the houses and 
their inmates should be brought to a conclusion as speedily as possible. A 
remorseless warfare against all insect and other pests: must be waged at all 
times
