344 THE ORCHID REVIEW, 
others, such as I have from time to time mentioned in these pages, delight in 
a large amount of direct sunshine, and are not put about in the slightest if 
grown with the Mexican Lelias, but on the other hand seem to prefer it 
and prosper. C. Lawrenceana is always late and slow growing. It is not 
a difficult species by any means, but it is simply a warmer growing kind 
than most others, and it should occupy at the present time the warmest 
house, at least until the new pseudobulbs are properly made up. 
Beware of the autumn flowering Cattleyas, and more especially C. 
labiata and C. Dowiana aurea, losing their new leaves by rot, caused by 
damping immediately the flower spike is cut off. This they are very apt to 
do, and when it occurs it is, of course, a misfortune, for the plant becomes 
greatly weakened. See that the sheath is wholly removed, and cut away close 
to the pseudobulb, with a sharp knife, the whole of the flower spike. When 
this precaution is taken it is usually effective, and the rot will rarely take 
place unless the conditions of the phere are greatly at fault. 
The time of year has now arrived when extra care should be exercised 
when watering. A bad or careless waterer is one who will go through his 
houses at fixed intervals and water everything indiscriminately. A good 
waterer will look over his plants every day, and will in the first place take 
into consideration the existing conditions of the weather; then, the 
condition of the plant, whether growing or dormant, deciduous or ever- 
green; the amount of compost round the roots, &c. Briefly speaking, a 
very little water will satisfy the requirements of all species that are more or 
less growing during winter; they will need to be kept just moist only, 
whilst those that are inactive should be watered frequently enough to keep 
them from shrivelling and plump, this will vary according to the species 
and the temperature they are in. For instance, there are two evergreen 
species, Coelogyne cristata and Dendrobium thyrsiflorum, which will rest in 
a cool department, where the temperature will average about 50°—say from 
45° to 55°, or even lower—and in such a temperature a very little water 
indeed will be found necessary to keep them plump; no more, in fact, then 
the leafless Dendrobium Wardianum, which will be in the same house, will 
teceive. With the exception of D. Devonianum, I do not like to keep 
the other Dendrobiums quite so cool when resting, as they will not stand it. 
D. nobile, D. Findl Dy: inode, and such like species, are, I 
fancy, better if not peually falling below 50°. 
Many Cypripediums are now in bloom, amongst others C. Spicerianum, 
C. insigne, and C. Charlesworthii will show up in force. These are some- 
times recommended as Cool house Orchids, but I find they really do best in 
the Intermediate house. Selenipedium Schlimii, S. longifolium, and S. X 
Sedeni are also in flower. The first-named is an intermediate species, but 
the others grow best in the warmest house.
