NOVEMBER, 1907.| THE ORCHID REVIEW. 330 
has been successfully hybridised with E. Endresii, E. ciliare and E. pseud- 
epidendrum, yielding the hybrids E. x Endresio-Wallisii, E. x Wallisio- 
ciliare, and E. X langleyense. The first-named re-crossed with E. Wallisii 
yielded E. X elegantulum, which again crossed with E. Wallisii produced 
E. X Clarissa, in which the species mentioned is represented three times. 
over. Thus we have a very interesting series of hybrids from the subject.

CALENDAR OF OPERATIONS FOR NOVEMBER. 
By W. P. Bounp, Gatton Park, Reigate. 
CALANTHES.—The foliage on most of the earlier flowering varieties: 
will by now be fully ripened, and they will need practically no water at 
all, but if they are staged in a position. where much fire heat reaches 
them, and the soil becomes dry very quickly, I do not think it well to 
deprive them of water entirely when the foliage has ripened. I believe 
in many cases the roots continue giving some sustenance to the newly- 
made bulb for some time after the leaves have fallen, and without doubt 
so long as there is a live root left a little water will be beneficial, though 
in some houses it may not be necessary. I speak more respecting the 
dryer class of house usually chosen to display the flowers of this popular 
Orchid. Give a neat stake to any spikes that are inclined to hang too 
much, but we find generally that it is only necessary to stake when several 
spikes have come from the growth of what was a single bulb at potting 
time. They are then apt to crowd themselves together if not staked out. 
These plants, when nicely arranged among ferns and light palms, present 
a picture during the dull season that every one must admire. 
Those that have only made weakly bulbs should not be allowed to- 
flower, and the benefit of having a rest will be readily seen when the plants. 
Start next season. 
The later-fowering varieties should still be kept watered as long as the: 
foliage remains green, gradually reducing the supply as the foliage ripens. 
PHAIO-CALANTHES.—A rather difficult problem presents itself in this 
case, where the deciduous Calanthes have been joined with the evergreen 
Phaius, and to meet it at all successfully I find it to be essential to go 
quite half way in the watering, allowing them to become ar

for any length of time during the winter season. The spikes os ae a sca
