THE ORCHID 
WORLD.

NOTES. 
The Kew Herbarium. — During the year 
igio, rather more than 16,000 specimens were 
received as donations or exchanges, while 
11,350 were acquired by purchase.

Vanda Sanderiana. — A few imported 
plants of this very beautiful species have 
recently arrived at Messrs. Charlesworth's 
in excellent condition. They are strongly 
e.stab]ished in the large cocoa-nut husks in 
which they have been grown, and to which 
the roots tenaciously cling, consequently 
there has been very little disturbance to the 
constitution of the plants, which are, unfortu- 
nately, difficult subjects to cultivate in this 
country. The growth of this species much 
resembles that of Vanda coerulea, but the 
stem is stouter and larger in all its parts, and 
more thickly leaved. It is a native of the 
Philippines, and usually flowers in September 
and October.

Seed Raising. — -Considerable difficulty is 
frequently experienced in the first attempts 
at raising any particular kind of Orchid seed, 
but after a certain period of almost futile 
results success is at last obtained. Cypripe- 
diums were formerly difficult subjects to raise, 
now they are comparatively easy. Cattleyas 
gave considerable trouble until a certain 
amount of experience had been gained. 
Odontoglossums, after many years of patient 
waiting, have at last been mastered, and many 
other instances might be given. A notable 
exception has, however, been achieved in the 
genus Sobralia, of which Messrs. Charles- 
worth have recently sown seed, produced by 
crossing S. macrantha and S. Charlesworthii, 
with astonishing results. Not only is the 
seed germinating freely on the surface of the 
compost in which the parent plants are 
growing, but when sown on some pots con- 
taining Cypripediums it germinated in almost 
a solid mass, the numerous seedlings almost 
smothering some young Cypripediums which 
had previously germinated on the same pot. 
Although very few of the seedlings will be 
kept, this is, in Mr. Charlesworth's opinion, 
the finest result so far achieved in the art of 
seed raising. 
P 
CCKLOGYNE SEEDLINGS. — Seed pocls of 
Orchids, in the majority of cases, ripen their 
seed almost on the same day of the year as 
the flowers were fertilised twelve months 
previously. There are, however, exceptions, 
a few requiring only nine or ten months for 
the completion of a good pod, the time 
varying with the genus or species used. In 
some species of Coelogyne considerably more
