24 THE ORCHID REVIEW. [JANUARY, 1923- 
For the ordinary people who want flowers in their houses, one big well- 
‘flowered Cypripedium is worth any number of bits. Those with a wide 
‘white margin to the dorsal sepal are best for producing a bright effect. We 
‘have a treasured piece of Cypripedium Boltonii, which is making three new 
growths, but it will be a year or two before we allow it to flower. 
Our Dendrobiums have been hung in the full sunlight and air for the 
last two months. They are promising well at the nodes, in some cases the 
full length of the bulbs. Some of them have been returned to the ‘‘ Monkey 
House” to flower, which is full up. When our previous efforts at 
Dendrobium culture are remembered one realizes what woolly brains we 
must have had. A few weeks ago we got a dozen Masdevallias from a 
friend. They were in a sad condition, having been bone-dry for a 
-considerable time, which is the last kind of treatment they require. We 
‘have, however, learned to go steadily with watering newly acquired plants 
until they get used to our conditions. They must have been wonderful 
specimens at one time, and are all good varieties, so we will enjoy their 
weird and wonderful flowers. We have put them on a shelf above the 
Odontoglossums, where the Odontiodas were, the latter having been moved 
a little nearer the heat for the winter. 
One does not like to talk about Odontoglossums being grown in the 
same house as Cattleyas and Dendrobiumis till a year or so has passed, but 
-an expert has given his judgment on their condition and described them as 
having “ bulky growths.” Certainly many of them are throwing good 
spikes. The Vandas in the cradle in the roof have been a failure so far as 
flowers are concerned, those in pots succeeding much better than those on 
blocks. Neither have been a real success. They have rooted and grown 
splendidly, so next year we will follow the advice of Mr. Mackay, who 
appears to have cultivated them very well, which is more than most 
people can say. Apparently they are a difficult subject to deal with at any 
time. 
BIFRENARIA HARRISONIZ.—Messrs. Veitch, in their Orchid Manual, 
state that the botanical and horticultural history of those Orchids that have 
been longest in cultivation is often most obscure, because in the early days 
of Orchid culture very little care was taken to ascertain or to record the 
dates of introduction. Bifrenaria Harrisoniz is an instance of this. All 
that is recorded respecting its origin is that it was sent by Mr. Wm. 
Harrison, a British merchant resident in Rio de Janeiro, to his brother 
Richard at Liverpool, and that on flowering it was named by Sir Wm. 
Hooker in compliment to another member of the family, Mrs. Arnold 
Harrison, the possessor of one of the finest collections of Orchids at that 
time. The probable date of introduction is thence 1821-22.
