-Aucust, 1916.] THE ORCHID REVIEW. tot 
previously advised for this genus will be found quite satisfactory. In most 
cases where these plants do not grow satisfactorily the cause is attributable 
to either too much or too little water at the roots, or a close saturated 
atmosphere. 
MaXILLARIAS.—At the present season such Maxillarias as M. luteoalba, 
grandiflora, Lehmannii, and many others may be repotted, should it be 
necessary. For such species as M. Sanderiana, and others which produce 
their flowers in a downward direction, shallow teak wood baskets, should be 
used. A compost made up of equal parts peat, Ax fibre, and osmunda fibre 
answers their requirements. The material should be made quite firm, and 
they should be grown at the warmest end of the Cool house. 
COcHLIODA N@TZLIANA, vulcanica, and sanguinea, with the numerous 
hybrids raised from them, may be treated in the same manner as Odonto- 
glossums. They succeed in the same material, and may be grown either in 
pots or shallow pans. 
OncipiuMs.—Those that had not made sufficient growth, last month to 
be repotted should, if the compost is sagan Ag have attention as soon 
-as possible. 
Ca@LocGyNneEs.—Plants of C. cristata are now making rapid growth, and 
well-established specimens must not be allowed to suffer for want of water. 
‘Cool-growing Ceelogynes delight in a damp situation whilst making their 
growth, and must not be exposed to a dry atmosphere or bright sunshine. 
‘The Ccelogynes which revel in a hot, moist atmosphere—of which C. 
pandurata is, perhaps, the most generally grown—may have new rooting 
material supplied to them when the young growths are about to push roots. 
‘A compost similar to that used for the green-leaved Cypripediums will 
answer their requirements. 
’ CALANTHES.—The deciduous Calanthes will now have filled their pots 
with roots, and may have an occasional watering with weak liquid manure. 
- The rule should be little and often, and it should be impressed upon those 
whose duty it is to apply it that no plant can stand strong doses of liquid 
manure. [ am afraid that more plants are injured from the misuses of 
manures than die for the want of it. As the leaves and bulbs get more 
‘matured they should receive more light and air to consolidate their growths, 
but care must be taken to prevent scorching. 
PLEIONES, as they complete their growth, should be inured to the light 
and receive more air than ‘heretofore. They should have sufficient 
water at the roots to keep the compost moist and the bulbs plump until the 
-leaves fall. When this occurs, and until the flower buds appear, they will 
need water in very limited quantities, after which the supply should be 
increased until the flowers are fully developed. After the flowers have 
faded the plants require sufficient water’ to keep the pseudobulbs from
