AuGUuST, 1917.] THE ORCHID REVIEW. 18s 
which produce their flowers in a downward direction are best grown in 
shallow teak-wood baskets, but pots or shallow pans answer the require- 
ments of the others. A clean fibrous compost is suitable, and should be 
pressed quite firmly round the base of the plants. 
CALANTHES in full growth may now have liberal supplies of water, and 
those which have filled their pots with roots may receive occasional 
waterings with weak liquid manure, but care must be taken that this is not 
too strong, or much harm may accrue. These plants now need plenty of 
heat, light, moisture, and air, and should be elevated clos: to the glass. 
The late-flowering section must still be watered with discretion. 
COCHLIODA AND ITS HYBRIDS.—Plants of Cochlioda Neetzliana, with its 
many hybrids, may be repotted in the same manner, and in a similar 
compost to that used for Miltonia vexillaria, which I will call the general 
utility compost, as it answers the requirements of this class of Orchids 
generally. The different hybrids vary somewhat in their time of growth, 
and it is obvious that they are not all ready for repotting at one season, 
therefore they should be taken when they reach the desired condition 
namely, when the young growths have obtained some few inches in length, 
and are about to push new roots. These all thrive in a moist position in 
the Cool house. Oncidioda Cooksoniz succeeds under the same conditions, 
but is best grown in an ordinary flower pot upon the stages, as in the case . 
of Oncidium macranthum, the other parent. There is no special difficulty 
in the cultivation of this and similar plants. Their thin leaves are subject 
to attacks of thrip, especially if their quarters area little too dry or hot. 
Bad attacks of insect pests are attributable, in most cases, to faulry 
conditions of the atmosphere. 
GENERAL REMARKS.— Towards the end of the month steps must be 
taken towards placing the different plants in their winter quarters. The 
glass should be throughly cleaned to admit all the light possible during the 
dark days of winter. The roofs of the different houses should be made 
absolutely watertight, as drip may mean the loss of a valuable plant. The 
heating apparatus of the houses, also the boilers, should be examined, and 
any faults made good, so that when severe weather is upon us they are 
thoroughly efficient. The best results cannot be expected or attained from 
_ faulty materials, and anything within reason should be done to enable 
those who are entrusted with the charge of valuable plants to pass through 
the winter months without any undue anxiety. The usual routine of 
cleaning, potting, &c., will comprise the principal work for the month. It 
may be impossible, under the present conditions, to maintain everything as 
one would like, but essentials should not be neglected, so that when we 
once again reach those good old normal times we may look back witl 
satisfaction and reap the benefit of a duty nobly done.
