THE ORCHID REVIEW, 165 
anum X Schroederz, and many others? I should only be too glad to show 
your correspondent these and many other plants, when I am sure he 
would only be too ready to reverse his opinion. 
A. KEELING. 
[If Mr. Keeling will send us a flower of the crosses in question, we will 
take care that our correspondent has an opportunity of seeing them, and 
also give an unbiased opinion on the points unde1 discussion. We know 
that when with Mr. Drewett he raised a hybrid from C. callosum xX 
Fairrieanum, called C. X Juno, whose correctness has never been called in 
question. But there is the recent record that Mr. Keeling exhibited at 
Manchester a plant called C. Fairrieanum, which the Orchid Committee 
were unanimously of opinion was not correctly named. What, then, was 
it ? And was it the parent of the hybrid now offered for sale by Mr. Keeling? 
We should like to see these matters cleared up. The charge now brought 
by Mr. Keeling against the horticultural press is too vague, and should be 
substantiated or withdrawn.—ED.| 
DENDROBIUM WARDIANUM AS A SEED-PARENT. 
WE have attempted to fertilize Dendrobium Wardianum with almost every 
Dendrobium species we have, and as a seed-parent have found it 
practically useless. A few capsules have appeared, but the contents 
generally were nil. As an experiment, we have fertilized it with Ward- 
ianum pollen, and with that of crassinode, and in these cases only with 
almost invariable success. As a pollen-parent the results are different.

CHANGE OF COLOUR AFTER FERTILISATION. 
The effect of fertilisation on the flowers of Orchids is well known, but a 
curious instance of change of colour in Vanda ccerulea is recorded in the 
Chronique Orchidéenne (p. 166). A plant of this species at the School of 
Horticulture, Ghent, bore a raceme of nine flowers, and, about mid-day on 
December 2nd last, eight of these were fertilised with their own pollen. 
Next morning, less than twenty hours after, these flowers had changed to 
white, though they showed no other change, while the single untouched 
flower retained its beautiful mauve tint. 
We once observed a somewhat analagous case in Odontoglossum X 
Andersonianum hebraicum. A single flower on a raceme of this plant was 
observed to be deep yellow while all the rest were of the usual primrose 
tint. Closer examination showed that in some way this flower had been
