176 THE ORCHID REVIEW. 
Odontoglossum crispum (Alexandrz) is the latest to be molested, and even 
this should not be done after September, 
I am also asked “‘the best way to establish newly imported Odonto- 
glossum Alexandre.” When these are purchased they are often in a 
desperately shrivelled condition, and a little careful treatment is necessary 
or Many may not recover. There must be no delay; neither must there be 
undue haste. All the dead and useless matter should be trimmed off, and 
the plants placed on a layer of sphagnum moss on the stage in the cool- 
house, in an upright position. The moss must be kept moist, but it is best 
not to wet the plants themselves until reaction has set in, when they will 
become plump and push out new roots. When this happens the plants may 
be potted and treated in the usual manner. The plan of placing newly 
imported Orchids under the stages, or hanging them up head downwards 
and syringing them, cannot be too strongly condemned. The system above 
recommended can be relied upon as being the best way to establish all 
species of Orchids. When it happens that the foliage-of any survives 
the journey, and especially of those where it is thick and persistent, 
such as Cattleyas and Lelias, every effort should be made to preserve 
it, as the foliage is a great source of strength. And to assist in this 
matter it is well, in addition to setting the plants on damp moss without 
delay, to protect from strong light for the first few days by placing on 
extra shading. 
Dendrobium Bensoniz, now in flower, is second to none in beauty, but 
as regards culture it is, perhaps, one of the most disappointing, It should 
be grown in very small pans or baskets, and suspended in the hottest 
possible part of the house, and watered very sparingly. This Orchid 
generally receives its death-blow during the winter, to avoid which it must 
then also be grown hot and dry. Dendrobium aggregatum is another 
Orchid requiring the same treatment ; also Diacrium (Epidendrum) bicornu- 
tum, which is now in bloom. Epidendrum Parkinsonianum is another 
which delights in such a position as advised for Oncidium splendidum, and 
the same may be said of the genus Brassavola. ; 
This is a good season to repot Ada aurantiaca. It may be grown with 
the cool Orchids during summer, but, like the Masdevallias, requires a 
warmer winter temperature, for if kept too cool the leaves turn a sickly tint 
and becomes badly spotted, and this should be avoided if possible, as they 
frequently then die off very rapidly. 
Red spider will probably give some trouble now, principally amongst the 
Dendrobiums. Where traces of it are found—and it may be detected by the 
leaves showing a whitish appearance on the under surface—the leaves 
should occasionally be sponged, either with clear water or some diluted 
insecticide ; but by all means avoid syringing the foliage with insecticide, 
as the force produced causes it to penetrate the leaves, thus producing 
great injury.
