THE ORCHID REVIEW. 281 
late to break as on those that are in an exhausted condition. Pinch off the 
flower buds as early as possible, and thus prevent them from flowering 
for a season, and it is almost sure to have the desired effect. 
Newly imported Cattleyas, Leelias, and. Dendrobiums, as I. have before 
remarked, grow freely enough for a few years, feeding, as it were, upon 
their home-made stamina, and it is when this is spent that it is seen 
whether the right or wrong system of Orchid growing is being followed. 
Among the Dendrobiums that are now bringing their new growths to 
maturity, and will require to be taken to a cooler house to further ripen, 
will be found the following :—D. crassinode, D. Findlayanum, D. aureum, 
D. Linawianum, D. nobile, D. crystallinum, D. Boxallii, D. tortile, D. x 
Leechianum, D. x Ainsworthii, and D. x Dominianum. The last three 
are perhaps the best known among garden hybrids, but there are a host 
of other beautiful hybrids in cultivation, for the proper treatment of which 
due regard must be had to their parentage, the hybrids requiring exactly 
the same treatment as the parents. The above-named sorts when at rest 
during winter delight in a temperature of about 50° in mild weather and 45° 
in very cold weather. There are also finishing up about this time D. 
thyrsiflorum, D. densiflorum, D. Farmeri, D. Dalhousianum, D. fimbriatum, 
D. chrysotoxum, and D. suavissimum, all of which are evergreen, and these 
kinds must now also be taken to a cooler house, but it should be noted that 
they will not stand quite so much bright sunshine now, nor quite such 
a low temperature during the winter as the foregoing varieties. The 
temperature of the Cattleya house suits them well. 
Most of the Dendrobium Wardianums will also now be fit to remove, 
and this species is one that will stand more cold when at rest than any of 
the other warm-growing sorts, and is the better for a temperature of 40° to 
45° in cold weather and until the end of February. True D. Wardianum 
may be had in bloom in January, but it is a-bad plan to force them thus, 
and the plants quickly deteriorate, whereas, if not allowed to flower until - 
the middle or end of March, they would remain strong and healthy. It is 
quite natural for the new growth to push quickly from the base; they 
seldom remain quite dormant for long; but such growths make but little 
progress during the winter, only becoming thick and sturdy, and evidently 
enjoy the cold at the proper season. The flower buds also soon begin to 
swell, and this they do slowly, but surely, in the cold dry atmosphere, and 
quickly expand in March, when a little extra warmth is applied. Owing, 
however, to the new growths and flower buds showing so early, the plants 
are thought to want more heat to hasten them along, and they are straight- 
way taken to a hot and moist-growing temperature, hence the reason of 
this beautiful Dendrobium being too often seen badly flowered and ina 
dilapidated condition. There are also others now finishing their pseudo- 
bulbs, but on account of their coming from-a hotter region are best if
