flowers at intervals, and are not, therefore, 
constantly in flower, as some persons might 
suppose from their being termed ‘ 1 Perpetual’ 
and he points out the following means of ob¬ 
taining from nearly all such a good second 
bloom: When the first bloom is not quite 
over, prune the Rose trees rather short, and 
even disleaf the parts which are retained. 
That being done, give a good watering so as 
to thoroughly moisten the soil about the 
roots. New shoots will soon push, and about 
two months afterwards they will have flower- 
buds at their ends. This mode of proceeding, 
he remarks, will, however, only prove suc¬ 
cessful as regards a second bloom in a toler¬ 
ably warm climate, for in others the weather 
will become too cold before the buds open. 
In this case, though a second bloom cannot be 
obtained by the above proceeding, bloom can 
be secured at two different periods by plant¬ 
ing the trees rather closely together, and, 
when they commence to flower, pruning every 
other one, which will have the effect of re¬ 
tarding the flowering of the plants so treated. 
In this way, after an interval of about seven 
weeks, say in the end of August, there will 
be Roses in as fine bloom as in the end of 
June, or beginning of July. 
Dios conn a Decaisneana. —A considerable 
amount of controversy has been going on in 
the French horticultural press as to whether 
this is a species or merely a variety. Which¬ 
ever it may be, M. Carriere records the fact 
that whilst nearly all the plants of Dios* 
corea batatas prove male, those of D. De¬ 
caisneana produce only female flowers; and 
he concludes that if the two were grown 
together seeds would probably be produced, 
from which new varieties might be obtained. 
OBITUARY. 
We regret to have to announce the death 
of Dr. Sclechtendae, Professor of Botany 
and Director of the Botanic G-ardens at Halle, 
and who was so well and so favourably known 
to botanists through his editorial labours in 
connection with the u Linn as a ” and the

CALENDAR OF OPERATIONS. 
STOVE AND ORCHID-HOUSE. 
Stove .—The object here will be to keep up 
as gay an appearance as possible during the 
dreary months of winter. All the large speci¬ 
men Clerodendrons, Allamandas, Echites, 
Achimenes, &c., should be removed to any 
spare house where a little heat is kept up, to 
winter. This will give room for the various 
plants which, having been struck last spring, 
and grown on through the summer, will now 
be in condition to bloom freely through the 
winter; let them be fully exposed to light. 
Orchids .-—Unless any plants show indications 
of a new growth, the moderately cool and dry 
treatment must he persevered in; such, how¬ 
ever, as are commencing to push must be potted 
at once and placed in more heat.. Keep plants 
in bloom in a dry part of the house. 
GREENHOUSE. 
Mixed Greenhouse .—As the plants are staged 
for the winter, let them have a surfacing of 
fresh soil; give air daily, and apply fire occa¬ 
sionally when wet, to dry up damp, and make 
the air of the house healthy. But little water¬ 
ing will be necessary at this season, except 
for such plants as have been a long time with¬ 
out shifting; let the watering be done in the 
morning, so that the house may get dry be¬ 
fore closing-up time. Camellias and Azaleas. 
—Keep cool and airy, unless early blooms 
are desired. A few free-blooming Azaleas 
may be placed in a moderately warm house, 
if wanted to bloom by Christmas. Cinerarias 
will now be growing very fast; fumigate if 
aphides are detected. This should be done 
with care, the foliage being very tender ; burn¬ 
ing a little tobacco two successive nights will 
be most effectual. Those for winter flowering- 
will now be throwing up their blooming-spikes, 
and may be selected from the general stock 
in the pit, and placed in front of the green¬ 
house. Shift any part of the young stock 
that is filling the pots with roots. Heaths 
and Epacrises. — Properly speaking, these 
plants should have a house to themselves, 
for they neither arrange well nor yet thrive 
with other plants. At this season they will 
require abundance of light and air. Do not 
apply fire heat to them unless the frost is very 
severe, and we may say at once none will be 
required this month, unless by day, during a 
continuance of wet weather. Pelaraoniums. 
1/ 
—Cleanliness during the winter has much to 
do with the successful cultivation of the 
Pelargonium. The glass, stages, and every 
part of the house should be clean, as well as 
the pots and everything about them. The 
house should also be kept dry, and not too 
cold at night. Give plenty of air on other 
occasions, and so that cold draughts may be 
avoided ; let the plants have plenty of room, 
keep them clear of dead leaves and green fly, 
and success will be tolerably certain. 
CONSERVATORY. 
As the entire stock is now in the house, air 
must be given on all favourable opportunities, 
to harden the plants well before winter. It 
will help to prevent mildew; and by applying 
a little fire on wet days at the same time, a 
close damp atmosphere, which is at all times 
injurious to the health of plants, will be 
avoided. Chrysanthemums should be brought 
in as they come into bloom, and with Epi-
