DAVIESIA. 
185 
DECIDUGUS CYPRESS. 
Thorn-Apple, D. Stramonium, now | of equal parts of sandy loam and 
naturalized in England; D. Metel, 
a dwarf species, common in gar- 
dens ; D. ceratocailon, a magnificent 
plant, and D. Tétula, the purple- 
flowered Thorn-Apple. They should 
be all raised on a hot-bed, and 
planted out in May. The splendid 
half-shrubby plant, with large, white, 
tube-shaped fragrant flowers, for- 
merly called Datira arborea, is 
now called Brugménsia suavéolens. 
This splendid plant may be grown 
in a large tub in the greenhouse, in 
heath-mould, during the winter ; 
and in May, a pit may be prepared 
for it about a foot wider in diameter 
than its tub. This pit should be 
partially filled with very rotten ma- 
nure and decayed leaves, and the 
Datura, being turned out of its tub, 
and its decayed roots pared off, may 
be put into the rich compost pre- 
pared for it, when it will grow most 
vigorously A plant treated in this 
manner in 1835 expanded 1050 flow- 
ers from the middle of May to the 
middle of September. About the 
last week in that month the plant 
was taken up out of the ground in 
which it had been growing, its roots 
and its branches were cut in, and it 
was again placed in a tub, to be kept 
in the greenhouse till the following 
spring. It must be observed, that 
the pit prepared for the Datura must 
be in soil which is either naturally 
dry, from being of a gravelly or 
sandy nature, or which has been well 
drained ; or that the bottom of the 
pit be filled with broken bricks; in 
order that the plant may be well 
and frequently watered while it is 
growing. Probably if its roots and 
collar were well protected, it might 
be left in the open air without injury 
during the winter. 
Davir'sta.— Legumindse.—Aus- 
tralian shrubs, with orange-yellow 
coloured pea-flowers ; which should 
be-grown in a greenhouse, in well- 
drained pots, and in a soil composed 
16* 
peat. ‘The pots will require to be 
often watered, but should have no 
saucers ; as the roots are easily 
withered by drought, or rotted by 
excess of moisture. The species 
are propagated by cuttings, struck 
in sand under a bell-glass, but with- 
out bottom heat. 
Day Lity.—See Hemerroca’.urs. 
Deap Lraves.—Few persons are 
aware of the great value of dead 
leaves to a florist; but the fact is, 
that when decayed, leaves form the 
best of all manures for flowering 
plants. In this state, they are called 
leaf-mould, or vegetable mould ; 
and under one. of these names they 
will be found continually referred to 
in all books treating of the culture 
of flowers. To prepare this vege- 
table-mould, the dead leaves should 
be swept up in November, and laid 
in a heap in the reserve-ground ; 
the heap should be occasionally 
turned over, say perhaps once a 
month, and in about a year, or at 
any rate, by the end of the second 
spring, the mould will be fit for use. 
Drapiy Nicurssape.— Atropa 
Belladénna, a plant of no beauty, 
and a deadly poison. 
Decayine Leaves.—Many trees 
and shrubs are very ornamental from 
the beautiful colours which their 
leaves assume in autumn}; and 
among these may be mentioned the 
Ampelopsis, or Virginian Creeper, 
the different kinds of Rhus or Su- 
mach, the Liquidambar, the Ameri- 
can Oaks and Maples, the Rhoao- 
dendrons, Azaleas, &c. Many large 
trees, such as the birch, the beech 
the oak, and the deciduous cypress 
are also very ornamental, from their 
decaying leaves. 
Decipuous Cypress. — Though 
these trees, in favourable situations, 
become too large to be included in 
a work like the present, yet as they 
are often introduced in shrubberies, 
when of a small size, it may be here
