314 THE ORCHID REVIEW. 
moisture, and growth is active which was previously very slow. But Iam 
afraid now that the plants will soon suffer from the almost total absence of 
sunshine. From the time of writing (September 15th) I don’t believe we 
have had here altogether during the last three or four weeks six hours of 
sunshine. I would prefer weather slightly more mixed and varied. 
Dendrobiums, however, have prospered this year more than usual. 
This seems to point to the fact that it is not only heat they like when 
growing, but air also. Undoubtedly they have had plenty of the latter this 
summer, for there has been no stagnant atmosphere. No sooner were the 
plants syringed than they were dry again, and this kind of thing Dendro- 
biums seem to enjoy. They have with but few exceptions made up really 
fine pseudobulbs, long and stout, in fact nothing so far left to be desired. 
If we can only get enough sun to thoroughly ripen them they will make a 
grand show of flower next spring. We are now gradually getting our 
spring flowering kinds in their winter quarters. This is done quite 
independent of any secondary growth that may have started again from the 
base ; such growths must fare as best they can; we must not keep the 
plants in a hot growing temperature just for their sake. 
Dendrobium Dearei is a species that requires a different and special 
treatment from most of the others during winter. It is never dormant, it 
is always either making new growth or flowering. By the appearance our 
plants now present one would think that the season was spring instead of 
autumn. The new growths are only a few inches high; consequently they 
must still be kept growing in a light position in the warmest and moistest 
house, and given a liberal supply of water, to which this species is very 
partial. D. Brymerianum is another often late to start away, making it 
very uncertain when the pseudobulbs will be pleted. It should now 
occupy a similar position, and be given a like treatment to the last-named 
until the main growths are ‘thade up, when it should at once be well rested in 
a temperature ranging between 50° and 60°, otherwise it will quickly push 
aerial growths from where the flowers should appear. D. Dalhousieanum is 
another that is also late; it should receive every encouragement until 
completed ; afterwards, like the last-named, it should be given a decided rest 
in the same temperature, until the flower spikes begin to push, about April, 
as these also are apt to turn to growths instead. 
Dendrobium crepidatum is a very pretty species, but with us behaves in 
an extraordinary manner, by appearing so healthy and then suddenly going 
off dead at almost any period of growth or rest alike. My experience and 
observation of this species is that it is most susceptible to a check through 
cold draughts, &c. It seems to require more heat than most of the other 
deciduous Dendrobiums, and I have no doubt it is collected from hot nooks 
and corners in its native habitats of Burma and Assam.
