THE ORCHID REVIEW. 123 
Cattleyas. Other sun-loving kinds are Thunias, Barkerias, Brassavolas, 
Rodriguezias, Mormodes, Cattleya Wakeriana, C. citrina, C. dolosa,. 
Cyrtopodiums, Dendrobium albo-sanguineum, D. ochreatum, D.-speciosum, 
Oncidium splendidum, Schomburgkias, and Vanda teres. Failing a Mexi- 
can house, a place should be reserved for these species at one part of the 
Cattleya or Intermediate house, which should be less thickly shaded than 
the other part. The syringe should now be well plied amongst them, 
using tepid soft water. 
The deciduous Calanthes should now be re-potted. Use pots in propor- 
tion to the size of the bulbs and the number inserted in one pot. Welll 
drain, about one half, as they are not deep rooting Orchids. Plant in an 
ordinary potting soil of fibrous loam, peat leafsoil, and sharp sand. Water 
very sparingly at first, and give a position in the warmest house, preferably 
on a shelf. . 
Sophronitis grandiflora is now starting to grow, and should have the 
necessary attention as to re-panning or top dressing. Being such a com- 
pact grower re-potting for the purpose of giving more root room is rarely 
necessary. It thrives best if suspended, is very partial to shade, and prefers 
plenty of moisture when growing, and until blooming is over, when it 
delights in a short rest. It succeeds best in the Cool house. 
Odontoglossum Rossii and O. Cervantesii, as they pass out of bloom, 
will remain inactive and at rest until about midsummer, and will therefore 
require exceedingly little water during that period. Small pans or baskets 
to grow in, very little root disturbance, and a very careful application of | 
water, even when growing, are the most essential points in keeping these 
species in a continually flourishing condition. They are very cool growing. 
Odontoglossum grande is now starting’ to form new roots and growths, 
and should be attended to. It does best in a rather generous soil, composed. 
of turfy loam, peat and sand, surfaced with sphagnum moss. Water care- 
fully after re-potting, but keep moist and in a growing condition. It 
really succeeds best in the Intermediate house, but will grow cool. 
Coelogyne cristata and its varieties will now be fit for re-potting. It is. 
not often that it requires it, the packing in of new material in any loose 
place, and the pegging down of new growths that show a tendency to grow 
over the rim, is generally all that is required. They do sometimes, of course, 
require larger pots and when so should have a compost of two parts lumpy 
peat, one of fibrous loam, and one of chopped sphagnum moss, and they 
should be potted rather firmly. It is generally not advisable to pull the 
moss to pieces when re-potting, but if the specimen is old, having a large 
number of old back pseudobulbs, it is better to do so, removing a large 
number of the old pseudobulbs, which are of no further use, and potting 
the younger portions of the plant together, which will grow much stronger
