generally the best mode, because the 
plants aie by that means kept dis- 
tine d the stronger cannot over- 
power the weaker. At the same 
time very strong ground plants, such 
as the white and yellow Water-lilies, 
do not flower freely unless in the 
free soil, or in very large tubs. 
There are few greenhouse aquatics, 
but a number of stove plants, which 
require to be grown in water; such 
as the Indian Lotus, or Nelumbium, 
&c., and these are necessarily grown 
in pots of moderate size. ‘The most | 
suitable soil is a rich loam. The | 
Papyrus, though properly speaking 
‘t is a marsh plant, is generally 
grown in an aquarium. See Marsu 
Pants. 
Aquite’cia. — Ranunculaceae. — 
Perennial herba- 
ceous plants, growing from one to two 
feet high, of which several species | 
are very ornamental ; more especial- 
ly the common Columbine, A. vul- 
garis, and its varieties, A. alpina, 
A. canadensis, and A. glandulosa. 
They any common soil that 
is dry ; species are increased 
by seed ich will keep a long 
time, and the varieties by division 
of the root. 
A’nazis._-Crucifere.—-W all-cress. 
Herbaceous plants, chiefly annuais 
and biennials, natives of Europe, 
many of which are remarkable for 
their early flowering. A. alpina 
has white and yellow flowers, which 
appear in March, and A. dlbida 
flowers the greater part of the year, 
conunencing in mild winters in Jan- 
uary, and preducing its large tufts | 
of white blossoms till October. Some 
- of the species and varieties, such as 
A, vérna, A. alpina nana, and A. 
bellidifolia, do not grow above three 
inches high, and are admirable plants 
for rockwork, or gardens of pots.

suffruticose plants, and stove shrubs, 
with umbels of small white flowers. 
The commonest species is A. spind-

diness, and for its thriving in any 
poor gravelly soil. There is a new 
species, A. japdénica, which is said 
to be very handsome. oe

Arsore'tum—A_ collection of 
trees and shrubs, containing only 
one or two plants of a kind, ar- 
ranged together, according to some 
system or method. ‘The most com- 
|mon arrangement is that of the 
Natural System; but the plants in 
an arboretum may be placed to- 
gether according to the countries 
of which they are natives; accord- 
ing to the soil in which they grow ; 
or according to their sizes and hab- 
its, or time of leafing, or flowering. 
In all small villa residemees an ar- 
boretum is the most offectnal means 
of procuring a maximum of enjoy- 
ment in a minimum of space, as far 
as trees and shrubs are concerned. 
To render an arboretum useful and 
interesting, each tree and shrub 
should be named. 
Arsours.—Seats or resting-places, 
forming terminations to walks, or 
fixed in retired parts of shrubberies 
or pleasure-grounds. In general, 
every straight walk ought to lead 
_to some object of use, as well as of 
beauty; and an arbour is one of 
‘those in most common use. The 
structure being formed, climbing 
plants, igneous or herbaceous, are 
planted all around it at the base of 
the trellis-work, or frame, against 
which, as they climb up, they ought 
_ to be tied and trained, so as to spread 
over the whole arbour. Some of the 
best plants for this purpose are the 
different species of Honeysuckle, 
Roses, and Clematis; and the La- 
burnum, the Peripléca greca, the 
mocarpus scdbra, Lophospermum, 
Rhodochiton, the Virginian ereeper, 
Cobea  scéndens, Menispermum 
canadensis, and ivy. ~
