they fix themselves, like the sucker 
of an insect. The other end after- 
wards detaches itself from the tree, 
and becomes leaves and_ shoots. 
The roots of the mistletoe descend 
between the bark and the young 
wood, and no intimate union takes 
place between the old wood of the 
parasite and its supporter. This is 
plainly shown in a piece of an old 
thorn, given to me by H. Long, 
Esq., of Farnham Lodge, to which 
a mistletoe of very large dimensions 
was attached. The wood of the 
mistletoe is of a very fine pale yellow- 
ish tinge, and it is as hard and of as 
fine a grain as box, which it greatly 
resembles, while that of the thorn is 
dark brown. 
Vrrex. — Verbendcee, — The 
Chaste tree. The principal species 
are V. A’gnus castus, which is a 
dwarf shrub, with whitish flowers, 
which will grow in any common 
soil, and will generally stand out in 
British gardens, though it is some- 
times killed by a severe winter; 
and V. incisa, which has pretty 
palmate leaves, and purple flowers, 
but it is so long before it puts out 
its leaves in spring, and looks so 
much as though it were dead before 
its leaves expand, that it is often 
thrown aside as worthless, when it 
is in perfect vigour ; it is generally 
kept in a greenhouse, and grows in 
peat and loam. Besides these, there 
are several hothouse species, natives 
of the East Indies, which are not 
worth eureting.

Wacisno'nsia Hann dorices.— 
Bulbous and tuberous-rooted plants 
with large panicles of very showy. 
flowers, which are generally yellow. 
These plants have rhizomas or under- » 
ground stems, in the seales of which, 
in some of the species, little bulbs 
form, which, if removed and planted, 
become distinct plants. These are 
the bulbous kinds. 
the same kind of rhizoma or fleshy 
under-ground stem, but no bulbs form 
in it. All the kinds are nearly har- 
dy ; and they will thrive in the open 
ground, provided the situation be 
tolerably dry, without its heii 
necessary to take up their roots 
during winter. 
WauLense’rota. — Campanula- 
ce@.—Perennial and annual plants, 
formerly considered as belonging to 
Campanula, and of which Campa- 
nula grandiflora is the type. They 
should all be grown in sandy loam, 
and they are propagated by seeds, 
and division of the roots. 
Wauks may be considered with 
reference to their direction, their 
construction, and their management. 
In a small garden, the direction of 
the main walks should generally be 
governed by the boundary lines ; 
and hence, ina plot of ground which 
is square or oblong, the walks should 
be straight and rectangular ; the ob- 
ject in such a case bemg to produce 
the beauties of regularity and sym- 
metry. On the other hand, when the 
boundaries of a garden are irregular, 
the surrounding walk may be irre- 
gular also; the object in this irregu- 
larity being to create variety by 
contrast in the direction. When a
