THE ORCHID WORLD. 
[August, 1913. 
Cattleya CITRINA. — With reference to 
the culture of this species, I know the late 
Sir Chas. Strickland gained considerable 
success by placing the plants in ordinary 
greenhouses until the latter part of the 
summer, when they were removed to a warm 
vmery. These plants remained vigorous for 
the long period of fifteen or sixteen years, 
and many of the last bulbs were larger than 
any of the former ones. Mr. Bonn)', of 
Hackney, whose name is kept in remembrance 
to-day by Odontoglossum crispum Bonny- 
anum, was another successful cultivator. 
One of his best plants carried no fewer than 
fourteen flowers, all of which were open at 
the same time. Mr. Bonny placed some 
plants on the upper surface of a horizontal 
raft, but he soon found that every new growth 
and flower endeavoured to lean over the 
edges of the raft, so he rightly concluded 
that this species grows naturally in a down- 
ward direction. — Old Ainaicur.

Cattleya citrina. — The writer m last 
month's ORCHID WORLD mentioned that 
Cattleya citrina was difficult to grow success- 
fully for any length of time. When in 
England I devoted some considerable 
attention to this Orchid, and for seven years 
had ten plants which bloomed regularly each 
year and never seemed to diminish either in 
size or vigour. They were grown in pans, 
on the south side of a Cattleya house, and 
^vhen in full growth water was given in large 
quantities, but immediately the new bulbs 
were made up no more water was afforded 
until the flower scapes were visible. The 
plants were always exposed to the full sun. 
One point to which I attribute much success 
was the damping every alternate evening, 
from April till July, with a weak solution of 
soot-water. The ammonia given off seemed 
to encourage exceptionally vigorous rooting ; 
so much so that when re-panning the plants, 
as was done every year, it was always a 
matter of necessity to break the pan before 
being able to remove the plant. Needless 
to say, care was always taken not to allow 
the plants to become wetted with the 
soot-water, the staging and pans being merely 
damped. I have had little success in raising 
from this Orchid, though I once succeeded 
in getting a good pod when crossed with 
C. aurea, but the resulting seedlings, three 
in number, were very weak, and after a 
miserable existence of about three years, 
died. — C. Alwyn Harrison, Oneglia, Italy.

Orchids at San Francisco, Cal., 
U.S.A. — It may be of interest to readers of 
the Orchid World to know that the people 
of this city are one of the most Orchid- 
saving communities that I have come in 
contact with in the United States of America. 
At this time of the year, when the people are 
away in their country homes, the supply of 
cut flowers is greater than the demand, and 
one can see the florists' shops with their 
windows full of fine specimen plants of 
Cattleya gigas, C. Gaskelliana, C. Mossias 
and Lselia purpurata ; also Phalaenopsis 
aniabilis, the beautiful P. Schilleriana, 
Odontoglossum citrosmum roseum and O. 
crispum. I have not seen very good success 
with Odontoglossums out here yet, although 
this is one of the finest temperatures, for 
we get the trade winds from the Pacific 
Ocean, and the house can be kept cool during 
the greater part of the year. There are a 
few private places where hybrid Orchids are 
being grown, and I have no doubt that there 
will be some fine collections out here in a 
few years' time, for when the people do 
anything along this line it is done wefl. 
Orchid growing has come to stay. In 1915 
the World's Panama-Pacific Exposition will 
be held in San Francisco, and for this event 
six greenhouses, each 25 feet by 100 feet, 
have been erected for the culture of decorative 
plants. — W . E. Eglington, San Francisco.

VANDA CCERULEA. — Since so much towards 
the successful cultivation of this Orchid 
depends upon the correct treatment afforded 
at the outset, a few remarks upon the method 
of re-establishing imported pieces may be of
