• THE GREEN-HOUSE, HOT-HOUSE, AND STOVE. 
hottse, Where it will flower earlier than upon 
Ilit- open wall. It succeeds in a soil of peat 
and loam, and is increased by eyes planted in 
puts, placed in a mild temperature. These 
must, of course, be taken off early in spring, 
cut to about an inch and a half in length, and 
covered about half an inch with mould, in the 
sime manner as practised for propagating vines. 
We believe this method was first practised in 
the Claremont-gardens, but is now pretty 
generally followed. Formerly, this plant was 
rare, and considered difficult to increase : the 
usual method being by cuttings of the roots, 
and by laying. Plants originated from single 
eyes frequently flower the same year, when 
about a foot high. 
" Passiflora Loudonii, and P. kerme- 
pixa, are two splendid varieties of this popular 
family. They are increased by cuttings of 
the young shoots planted in sand, and covered 
with a glass, and also by layers and seeds, 
when the latter can be obtained. Any mode- 
rately rich, light soil suits them ; and, con- 
trary to the generality of the genus, they will 
flower well in a low temperature. Speaking 
of this plant, Mr. Lindley says, — ' This is, 
beyond all comparison, the most beautiful 
species in cultivation, except racemosa. Its 
flowers have a richness of colour which art 
cannot imitate ; they are produced in great 
abundance at almost all seasons ; and in con- 
sequence of the length of the slender stalks 
from which they singly hang, the whole plant 
has a graceful aspect, which is unrivalled even 
among Passion-flowers.' It is rather a singular 
circumstance in the family of Passiflora, that, 
although all of them are fruit-bearing plants, 
they are shy in fruiting unless impregnated 
with the pollen of each other instead of that 
of their own. 
" Tacsonia pinnatistipula. — This elegant 
climbing plant is closely related to Passiflora : 
it is a native of China and Peru, from which 
place it was introduced by Mrs. Marryat, of 
Wimbledon, one of our most eminent patrons 
of floriculture. It is easily increased by cut- 
tings of the previous year's growth, planted in 
pots filled with sand or sandy loam, and placed 
in a slight bottom heat. It produces abun- 
dance of fruit, from which seeds can be ob- 
tained, and vegetates freely in light, rich mould. 
They should be sown as soon as gathered." —

The Bulb-house comes next, and, inde- 
pendently of the excellent directions for the 
treatment of all the principal families, there is 
a catalogue of everything beautiful belonging 
to it. We then come to the Succulent- house, 
in the heating of which the author introduces 
various plans, and refers to the succulent- 
house at Claremont, which in its day was 
eertainly one of the most perfect things of the 
kind. The parties who grow succulents in 
any degree of perfection, or to any extent, arc 
not numerous, and perhaps the most beautiful 
and ingenious thing of the day is that at Mr. 
Williams's, at Hendon ; the neatness, extent, 
arrangement, and general appearance of the 
collection there renders it one of the lions of 
the metropolis. Although thei'e are more 
extensive and more costly collections, there 
are none more interesting. The treatment of 
these subjects is judicious, and the instructions 
plain, and when all the varied tribes of plants 
which form the chief features in a succulent- 
house, have been enumerated, we pass to the 
mixed green-house, which affects every body 
who has only one, and this extends to tens 
of thousands. Here we have excellent arrange- 
ments laid down in very understandable lan- 
guage, highly useful in their collective cha- 
racter. And after these we have notes of the 
different families, which we think it quite fair 
to quote; and as, in the order of the book, there 
are paragraphs about soil, and shifting or 
potting, we will precede the notes by quoting 
these also: — 
" Soil. — The majority of green-house plants 
which come under the present head will flourish 
to the utmost perfection in a soil composed of 
half light turfy sandy loam and peat earth. 
Some few, such as Protea, prefer a rich loam 
of a middling texture, and others, such as 
Pimelea, Roella, Lechenaultia, prefer a sandy 
peat alone. The fresh soil of a properly se- 
lected piece of uncultivated land, having abun- 
dance of fibrous vegetable matter contained in 
it, should be preferred. All garden mould, or 
that which has been under a state of cultiva- 
tion, should be carefully rejected. 
" Shifting or Potting. — Enough has been 
already said upon this subject, under the various 
heads already noticed, to render any lengthened 
description of" the process unnecessary here ; 
we will only refer to what has been said on 
the subject, and state that all green-house 
plants should be shifted at least once a year, 
many of them oftener, according to their habits 
of growth or the purpose for which they may 
be intended. There is one very general and 
very great fault in shifting plants, and that is, 
placing them in too large pots ; nor is this a 
subject that any written directions can explain 
or rectify. We know of no other rule that 
can be at all considered as bearing on the case, 
or that we have words to explain, other than 
proportioning the size of the pot to the number, 
size, and form of the roots. Thus a Heath, or 
Azalea, requires a much less pot to grow in 
than a Paeonia or Fuchsia of the same size ; 
and such plants as Chrysanthemum, Calceo- 
laria, &c, that require to be grown rapidly to 
increase the number and size of their flowers, 
and also those being only herbaceous, that is,
