THE ORCHID REVIEW. 213 
late blooming Odontoglossums in the Cool House which can be dealt with 
now. 
On looking round, a few plants may now be found which have already 
completed their new growths, and these, of course, should have the lightest, 
driest and most airy positions secured for them, but the supplies of water 
at the roots should not at present be greatly diminished, because the roots 
are still actively running, and drought at the present juncture would 
probably cause secondary growths, which are better if absent. Among 
these will be some of the earliest Cattleyas, such as C. Warscewiczil, 
Gaskelliana, and C. Warneri, which bloom immediately the new psuedo- 
bulb is completed, either with or without a sheath, and those failing to do 
so quickly will most probably fail to do so this year, no matter what 
treatment is given. Some of the earliest of the Dendrobiums and Thunias 
may also be finishing up, and these it would be better to shift into 
a greenhouse or vinery for a few months as they finish off, but, as 
before said, without reducing the water. 
Dendrobium Falconeri is a most lovely species when well grown, but 
is sometimes rather troublesome to keep for long in a healthy state. It 
greatly prefers an intermediate temperature, shade, and an abundance of 
atmospheric moisture when growing, but should be rested in a cool 
temperature throughout the winter months. Either a block, raft, or the 
stem of a tree fern is preferable to a pan or basket, because its roots, which 
are largely aerial, and appear from almost every node, have then something 
to which they can cling and find support. When fixing this to a raft— 
which I prefer, because the air has more play between the bars, keeping the 
roots in a more healthy state—a number of plants can be put together at 
the required distances apart, and a fine specimen thus built up, but no 
sphagnum or other material should be fixed round the base or roots, 
otherwise such material immediately round the roots will keep continually 
soddened by the frequent syringing, while the rest of the raft is dry; a 
condition of things which must, if possible, be avoided in the cultivation 
of all block or raft Orchids. 
Pescatoreas and Bolleas are nearly allied, and very beautiful and 
interesting Orchids they are. They are easy of cultivation, provided 
suitable conditions are found for them, and when so they grow clean, 
handsome and graceful foliage, which is a pleasure to see; but unless 
something nearly approaching the correct treatment can be given, they are 
rather unsatisfactory plants to take in hand. An ordinary well-balanced 
East Indian house or stove, not too hot, meets their requirements best. 
They should there occupy a position tolerably well shaded, and where the 
atmosphere keeps pretty moist and evenly balanced. They may be grown 
either in pots or baskets, and their roots require nothing better than
