later. The sepals and petals are light apple-green with a few minute brown 
spots, and the lip yellowish green, densely spotted and suffused with warm 
shining brown. Habitat not known.—Kew Bull., 1895, p. 284. 
SCELOCHILUS CARINATUS, Rolfe.—An interesting little plant, introduced 
from the Andes by Mr. F. C. Lehmann, and flowered in the collection 
of Sir Trevor Lawrence, Bart., in September last. The sepals are light 
yellow, the petals maroon purple with a white margin, and the lip whitish 
with maroon-purple blotch at the base of the reflexed limb.—Kew Bull., 
1895, p- 284. 
SACCOLABIUM HAINANENSE, Rolfe.—Closely allied to the Himalayan S. 
gemmatum, Lindl., but with broader flat leaves. It was introduced from 
Hainan bythe Rev. B. C. Henry, and was sent from the Hongkong Botanic 
Garden to Kew, where it floweredin March last. The petalsand dorsal sepal 
are lilac-purple, and the rest of the flower white.—Kew Bull., 1895, p. 284-

CULTIVATION OF ODONTOGLOSSUMS. 
Mucu has been said with regard to the cultivation of Od gl 
crispum and its varieties ; and perhaps a few notes will be acceptable, as 
to my practice at Arddarroch. We received an importation of 4,000 plants 
of O. crispum here in April, 1894, and most of them were potted up in a 
mixture of polypodium-fibre and sphagnum moss in equal proportions, the 
material being chopped up with a chaff-cutting machine. The larger plants 
were put into as small pots as convenient for the size of the plants, and the 
smaller ones placed ina bed of the same material. They were placed ina 
house facing north and south, the former being placed on an open stage, 
well up to the glass, which I find a great advantage to all Orchids, especially 
Odontoglossums. At first they were watered very sparingly, only receiving 
a thorough soaking once in four weeks, but were syringed over-head on fine 
days until the pots were filled with roots ; afterwards only receiving water 
when thoroughly dry. Under this treatment I find they thrive satisfactorily. 
As regards the potting of established plants, I do not bind myself to any 
hard and fast rule. I like to pot a plant when it needs potting, but just 
after it commences to grow; as it is then sending forth its new roots. 
September and October I find the most suitable months for this operation, 
as it isthen when most of the plants are starting to grow, and they then 
have time to establish th before the hot pp I do not believe 
in potting Odontoglossums in spring, for I find that disturbing them at the 
roots at that time of the year is hurtful to the plants, as they have no time 
to get re-established before the hot weather sets in. The material I find 
best for established plants is good peat and sphagnum moss in equal pro-
