174 THE ORCHID REVIEW. [JUNE, 1912. 
AERIDES JAPONICUM. 
A FLOWER has been sent for determination of this very distinct and 
interesting Orchid, with a request for its history. It is a native of Japan, 
whence it was originally introduced in 1862 by M. J. Linden. It was 
described in the following year (Linden & Rchb. f. in Hamb. Gart. Lett., 
1863, p. 210), the authors describing it as allied to A. radicosum, A. Rich. 
It is interesting to note that at the International Exhibition held in London 
in 1866 it obtained the first prize for a new Orchid shown for the first time 
in flower. Soon afterwards it was figured in the Botanical Magazine 
(t. 5798), when Sir Joseph Hooker remarked: “ The presence of Aérides in 
so high a northern latitude in Japan is a remarkable fact in Botanical 
Geography, as testifying to the warmth of the southern coasts of that 
Archipelago, and to the extension of a Malayan type of vegetation to so 
high a parallel.” According to Franchet & Savatier it grows on shrubs in 
the hilly district of Kiusiu, and in other places. It is one of the smallest 
species in the genus, which, perhaps, indicates the climatic influence of its 
northern latitude. It is also one of the few species of the Aérides group 
that can be successfully grown in the Odontoglossum house. Out of 
flower it looks more like a small Phalznopsis amabilis than an Aérides. It 
bears short lax racemes of seven to ten fragrant flowers, which are of a 
pale greenish white, sometimes barred with brown on the lateral sepals, 
and the lip white, with a purple keel and numerous purple blotches on the 
front lobe. It succeeds well in a shallow pan or basket suspended from 
the roof of the Cool house. 
RHE AMATEUR’S COLLECTION. 
By C. Atwyn Harrison, F.R.H.S. 
Coot House. 
THE treatment required by the inmates of this house will be much the same 
as advised in my last month’s article. The. amount of water, however, 
needed by all plants in full growth and in flower, will be considerably more 
than has yet been required this season. Look over the entire stock of 
Orchids daily, and to all which are active give a good dose. Damping will 
be needed in the morning, at noon, and again at three in the afternoon. © :As 
the sun has increased in force, the blinds will now have to be lowered ‘earlier 
and raised later than stated for last month. Keep the temperature as low 
as possible during ‘the day, but maintain a moist even temperature of 65° 
Fahr. at night. The plants will need spraying over their leaves in the 
morning, and again when the house is damped and shut up in the evening. - 
Any hybrids of Odontoglossum which are starting into growth can be 
repotted if they require it, using the compost advised in previous articles.
