THE ORCHID REVIEW. 169 
the moisture-holding material should be of such a body as not to be too 
readily influenced by the hot-water pipes. The top staging should be far 
enough away from the lower one to admit of the free circulation of air 
between the two. When too close together, the air remains more or less 
stagnant, there being no upward current through the plants. 
A good body of coke under the pipes, and blue, corrugated, Staffordshire 
bricks for a pathway make excellent flooring.

DENDROBIUM x SCHNEIDERIANUM. 
IT is very interesting to be able to compare a hybrid with its two parents, 
and to see the way the different characters are combined. For this reason 
we now reproduce a photograph taken by Mr. Eric Ball, of Ashford, 
Wilmslow, showing the charming hybrid Dendrobium X Schneiderianum,

together with its two parents, D. Findlayanum ? and D.aureum ¢. The 
seed parent in this case, it will be observed, has exerted a preponderating 
influence, and, indeed, ifthe history of the cross were not known, it would 
be difficult to say what modifying influence had been at work, at all events 
so far as the photograph is concerned, though in the living flower the 
characters of D. aureum are less difficult to trace. D. X Schneiderianum 
was obtained from a cross effected in the collection of Mr. Oscar Schneider, 
of Fallowfield, near Manchester, but the seedlings were raised by 
Mr. W. Holmes, gardener to M. C. Moseley, Esq., Grange Thorp, Rusholme, 
Manchester, and the first flowers appeared in 1887, when it was described 
by the late Professor Reichenbach.
