270 THE ORCHID REVIEW. [SEPTEMBER, 190}. 
some may still be good, it is necessary to thoroughly overhaul some each 
year, and it is also desirable from time to time to cut back some of the 
growths that have produced flowers to within six inches of the base. The 
best results are brought about by not having much, if any, zrial growth, 
and encouraging those from the base. When the eerial growths are kept 
well cut out the basal growths come away more freely, and it is from those 
that the best heads of flowers come. They are not very particular as regards 
compost, and sucha one as advised for Epiphronitis would be very suitable. 
Give them a position where plenty of light can reach them, in the Cattleya 
and Intermediate houses, and syringe them yery freely overhead. Some 
very good effects can be brought about by training them on walls or pillars 
in the warmer Orchid houses, and, if treated thus and planted out, they do 
wonderfully well, and also provide good material for cutting. 
ODONTIODAS. 
WHEN THIS remarkable little race becomes more numerous, and is better 
known, there is a possibility of its equalling, and perhaps excelling, in 
popularity the much-prized genus of Odontoglossum. Odontiodas have 
recently evoked much discussion, and a few notes respecting them have 
already been published, but nothing in the form of a complete list has 
appeared, hence it may now be opportune to give one. The year 1908 
should materially add to the interest taken in the “new red race” of 
Orchids, for there can be little doubt but that the influence of red will be 
even greater than is that of O. Harryanum, for it will create a new colour 
in Odontoglossums which will permeate the whole family, and ramify to all 
the allied genera, as and when the linking-up operation is effected by the 
hybridist. 
Since the time that Odontioda Vuylstekez appeared at the Temple 
Flower Show of May 31st, 1904, and created such a furore, almost all 
raisers of Orchids have taken the matter in hand, and, considering the 
short time that has passed, great progress has been made, and seedlings of 
similar and other crosses exist in many parts of England and on the 
Continent. 
Mr. Charlesworth had Previously raised plants which in due time 
bloomed, and were named Odontioda heatonesis, O. Bohnhoffie and O. 
Bradshawiz. Mr. Stevens, in the « Walton Grange Collection,” has also 
several seedlings of a similar cross to that which produced the fine O. 
Vuylstekez, and some of these should flower in 1908. 
In these days, when size of flower and value of plant are the objects, the 
first results in the primary hybrids will be in many cases disappointing, for 
the difficulty of raising upon a large species of Odontoglossum is great, but 
to those persens who do not especially consider sige and colour, the results
