“THE ORCHID REVIEW 53 
maintained with a free admittance of fresh air. If the outside conditions 
are such as to prevent the ventilators being opened, then it would be better 
to reduce the above figures 5 degrees all round. Make do with as little 
warmth from the hot water pipes as possible. For these warm houses, 
however, a little will still be required during the night, and perhaps also by 
day. The Dendrobiums, with the exception of D. Bensonz, D. Parishii, 
D. crystallinum, D. nodatum, and a few other late flowering kinds, are now 
all potted up, and are making new growth, and will henceforth delight in a 
good deal of heat and moisture, providing, as before stated, air is not denied 
them. Let them be suspended in pans or baskets well up to the light, but 
guard just at present against keeping the compost too saturated, or the 
new growths are apt to damp off. It is yet rather too early in the season 
to commence syringing, unless it is the D. Wardianums, which could be 
syringed and given a position at the coolest part of the house. Be on the 
alert for red spider in this department, which is sure to come, and 
more especially if the temperature is too hot or dry. The Coryanthes, 
Spathoglottis, Catasetums, and such like species, should now be basketed 
up, and put in growing order. 
The mention of baskets reminds me of the improved one (West's 
Patent). I have now tried it, and believe it is certainly an improvement 
on the old one, for two most decided reasons—firstly, being so much lighter, 
and secondly, by facilitating the work of watering. 
There are but few Dendrobiums which can be grown in a warm green- 
house temperature with other greenhouse plants, but D. Falconeri is one of 
them that will. It is now showing for bloom, and should receive more 
water. D. Falconeri grows best when fixed to a teak wood raft. During 
the summer when making growth it should be given copious supplies of 
water by being syringed several times daily, but during the winter it should 
have long intervals of absolute drought until the spring, when the flower- 
buds show. D. speciosum, an Australian species, is another that will grow 
well in the same temperature, as will also D. Jamesianum, and its near 
ally D. infundibulum. The latter two kinds should be grown in small pans 
and suspended. 
A question that beats me is one asking—‘ How to grow Oncidium 
Jonesianum,” and I am obliged, for all practical purposes, to give it up. I 
remember about ten or eleven years ago the first importation of some 
thousands coming to this country; they all arrived in grand condition, and 
were fine strong healthy plants. It was new and pretty, and consequently 
the sale was brisk. This importation was followed by another, and yet 
another, till O. Jonesianum was one of the most common Orchids in the 
country. It seemed to possess a very robust Coaaeaieine, and come away 
well, soon making a good big p ly followed by a fine
