118 THE ORCHID REVIEW. 
In cultural matters a good deal depends on where a Dendrobium is wintered. 
This reminds me that when writing the February Calendar I made a some- 
what misleading remark by indicating that Dendrobium crassinode and primu- 
linum required similar treatment to D. Wardianum. This applies only to 
treatment during summer, but the low temperature enjoyed by the latter 
during winter would probably kill the two former species, especially 
D. primulinum, which should never be wintered lower than Intermediate 
house temperature. Respecting the many garden hybrids now in culti- 
vation, it may be remarked that the treatment best suited for the parent 
species is generally applicable, and thus records of parentages are useful for 
cultural purposes. 
The deciduous Calanthes will require repotting this month. C. xX 
Veitchii and others of the vestita group are most useful for winter blooming. 
Rich sandy loam is a capital thing to grow them in, and the pots should be 
half-filled with drainage. They grow well either singly, or several in a pot, 
if care be taken that the pot selected be not over large. Pot firmly, and 
secure the pseudobulb with a small stick. Calanthes succeed best in the 
temperature of the warmest house, and must be watered with great care, 
particularly from the time of repotting until the roots have well filled the 
pots. 
_ A gardener remarked to me the other day that Calanthes seemed to him 
to be generally better grown in general collections than in regular Orchid 
collections. His argument was that those who did not profess to understand 
Orchids grew these Calanthes better along with their ordinary stove plants 
than did the Orchid grower who practically cultivated nothing but Orchids. 
I conceded the point, for I have observed the selfsame thing; not always, 
but twice out of every three cases, and the reason is not far to seek. The 
general man eventually finds a position in his Stove or, perhaps, the Cucumber 
house, which he finds well adapted for the growth of his Calanthes, and is 
able to reserve this position each year ; thus success is assured. But with 
the regular Orchid grower Calanthes are often ousted from the most suitable 
positions by more rare and costly species, which must have the best places 
and the lion’s share of attention. Not that he neglects his Calanthes in 
respect to watering and other matters ; perhaps they get a little too much 
attention and kindly coddling, and thus in trying to grow his plants too well 
he fails. 
There.are other Orchids besides Calanthes that resent too much meddling 
or interfering with, and I have little doubt that they frequently get worried 
to death by these means. We get over-anxious about our pets ; too careful 
that they shall have water at regular intervals ; and by a too frequent repe- 
tition of dose after dose the compost gets into a bad state, and the plant 
becomes unhealthy, and a prey to all kinds of diseases. Again, by our over-
