368 THE ORCHID REVIEW. 
Haynaldianum is also flowering well, and several other forms are pushing 
up their scapes very freely, promising a good succession of bloom.  Seleni- 
pedium Schlimii and some of its hybrids are also flowering freely. 
The Oncidiums are now very gay, particularly O. crispum, Forbesii, 
and varicosum, the variety Rogersii of the latter being a great improvement 
on the type. The flowers of these beautiful plants, arranged as they are 
in loose branching panicles, might almost be compared to swarms of gay 
butterflies. Several of the smaller species are also very effective, and 
amongst them I must not forget the elegant little O. cheirophorum. 
Trichosma suavis is a plant everyone should grow. It flowers very 
freely at this season, and is deliciously fragrant, besides giving little trouble 
to grow it well. Sophronitis grandiflora and Lelia x Eyermaniana are 
now well out, also Maxillaria picta and Angrecum Leonis, together with a 
number of less showy things, and altogether the houses are particularly gay 
just at present. 
Among the plants now throwing up strongly must be enumerated the 
winter-flowering species of Phalznopsis, the Zygopetalums, Leelia anceps, 
and several others which I have not time to enumerate at present, though 
they will doubtless form materials for future notes.

CALENDAR OF OPERATIONS FOR DECEMBER. 
By H. A. BURBERRY, Highbury, Moor Green, Birmingham. 
DECEMBER is 4 month of comparative inactivity with all genera of Orchids, 
many are at rest but still require careful treatment and watchful attendance, 
in order to keep them plump and healthy. The growth of others moves 
but slowly along, while those producing flower spikes are loth to expand — 
their blossoms. Indeed, during the depth of winter it is not unusual for 
of the plant is thus lost until another season. This premature decay of 
the flower buds is the result of a variety of causes. One prolific source of 
mischief is the atmosphere becoming impregnated with some foreign sub- 
stance which is most distasteful to the tender exotic. This occurs mostly 
in large towns. But even in clear country places misfortunes in this direc- 
tion are not unknown, and in many instances the grower is more or less 
powerless to prevent them. It is exceedingly difficult at times to maintain 
an artificial atmosphere during the short dark days of winter, which is all 
that the inmates of the different departments require. We must however, 
do our best to avert the casualties which might otherwise occur. 
The following temperatures should be Maintained as nearly as possible 
under the circumstances and with the means at command :-—
