far advanced. Z. crinitum and Z. Mackayi are very similar to this species, 
requiring the same treatment, and also bloom in winter. Z. Gautieri is a 
very handsome species, flowering at the same period, but different in habit 
from the foregoing. It is best grown on a tree fern stem, but failing that, a 
teakwood raft having a little moss and peat about it, is a good substitute. 
It should be suspended in the Intermediate house, and well supplied with 
moisture during the summer months. 
Cattleya labiata having now practically done duty for the present 
season, the house will look somewhat bare until the bulk of the Trianzs 
again put in their appearance. A few stray ones may be in bloom.by 
Christmas, and by then there will also be C. Percivaliana. This is 
undoubtedly a very pretty species, especially the better varieties, but it is 
at the same time one of the most unsatisfactory species I have ever had tc 
deal with. It is easy enough to grow fine pseudobulbs, with equally fine 
flowering sheaths, but it is very disappointing when the flower spikes refuse 
to come out, and such is frequently the case. They seem to prefer the 
pure air of the country, and during the period that the blooms are in 
formation extremes in heat or cold should be careful avoided, and also 
extremes in the amount of moisture at the root. C. quadricolor—often 
called C. chocoensis, or sometimes labelled C. Trianze chocoensis—will also 
be in evidence, as it is a particularly early species to bloom. Some varieties 
are very beautiful, especially those that are almost white. C. Warneri is 
now starting into active growth, and if re-potting is necessary it should now 
be performed very carefully indeed. It is best grown in hanging baskets, 
and from now onwards should occupy a fairly warm position in_ the 
Intermediate house, and be given sufficient moisture to support the new 
growths, and to enable them to move slowly and healthily along. 
Dendrobium ochreatum (Cambridgeanum) is another very peculiar 
Orchid which starts regularly to make its new growths in mid-winter. It is 
no good trying to keep them back, for they will come, and if not supported 
fairly well the result is that we get small, undersized, starved pseudobulbs, 
and the plant dwindles away. I have previously advised that this Epes 
should be grown in pans or baskets, in a well exposed position, where it 
gets the full power of the sun’s rays, such as the Mexican house would 
provide. It should occupy such a position now, and receive just sufficient 
moisture at the root to support its new growths, and keep the old bulbs 
plump. By the time the new bulbs are formed, the sun will again be 
st : : ke those new bulbs flower 
gaining some power, and if this does not ma ne hi 
immediately, as they should quite naturally do, in all probability nothing 
else will. One should aim to give sufficient nourishment in the water to 
ensure large pseudobulbs, for the plant is naturally a shy bloomer, as it : 
only when well-grown that it blooms to perfection. At the same time
