flowers of this Sobralia, like others of the class, are very 
fugitive, but they mainta; 
a continuous succession, flowering from 
the same sheath for some time ; 
as one flower fades another bud appears, so that quantities of flow 
before the sheath is exhausted. It blooms during August 
native of Costa Rica. 
This Sobralia requires the same treatment as that recommended under plate 250: 
for S. xantholeuca, where all details of culture will be found. These plants are 
subject to thrips and red spider, more especially if they are grown in too dry an 
atmosphere, combined with high temperature; but if our cultural instructions are 
followed out they will not be so liable to these pests. The red spider may be 
kept in subjection by carefully syringing the plants during warm weather, which 
will be highly beneficial to them, in addition to ridding them of their insect 
enemies; a sponge and clean water should also be frequently applied for the removal 
of these pests, as, if allowed to remain, they greatly disfigure the foliage by rob- 
bing the plant of its juices, which they cannot long endure, but will speedily get 
into an unhealthy condition and dwindle away. Cleanliness, although one of the 
simplest, is, nevertheless, one of the most. essential principles in the cultivation of 
Orchids. When found to be infested with pests of any kind the plants should 
be thoroughly cleansed, 
as soon 
ers are produced 
and September, and is a 
and when this is accomplished a careful and incessant 
watch must be kept over them, in order to prevent a relapse. 
Oprruary.—THomas Moorr.—We regret to record the death of Mr. Thomas 
Moore, F.L.S., at his residence, The Botanic Gardens, Chelsea, on New Year’s Day, 
in the sixty-sixth year of his age. He had been suffering for some time past, 
but up to within a short time of his death he had been able to attend to his 
botanical pursuits, when a severe cold and cough overtook him, and he was com- 
pelled to keep his bed for a few days. We had a card from him only two days 
before the new year to say that he should, as usual (when better), be able to attend 
to the Botanical part of the Orchid Album. With the deepest regret to his family 
and friends he passed away on New Year’s morning. His death will be felt by all 
who knew him, for he was a kind-hearted, and most unassuming man; always ready to 
give advice to those who sought it, and whatever information he gave might be 
safely relied upon, so that he has left a prominent name among horticulturists, both 
at home and abroad, and in fact with all who came in contact with him. His 
knowledge of plants of all descriptions was unsurpassed in any man we have known. 
We have travelled many hundreds of miles with him to various shows, and were 
often judges together, and fully recognised him to be one of the very best judges 
of plants we have ever met. Mr. Moore was the author of many standard works. 
upon Ferns, both British and Exotic. He had also been associated with many : 
horticultural works, both as editor and sub-editor, commencing his literary career with
