a gentle watering settles them clown 
firmly, and their after-management, until 
the blooming season arrives, is merely to 
secure them all the air possible, and to 
keep them moderately moist. As the 
flower-stems rise they should be fastened 
to sticks, and the number of buds re¬ 
duced to about three or four- for strong 
plants, and not more than one upon 
those which may be weakly; the same 
attention to tying the pods, shading and 
carding the flowers, will be necessary 
for these as for pinks, though where a 
large collection is grown, it is usual to 
have a frame or stage covered with can¬ 
vass, which, by means of rollers, . is 
wound up or let down at pleasure; with 
the command of such a convenience, the 
beginner must be careful that he does 
not injure his plants by too much nurs¬ 
ing, as they are very impatient of a 
confined atmosphere; plenty of pure 
water, and occasionally licpiid manure, 
should be given through the blooming 
season. 
New varieties of each of the foregoing 
are obtained from seed,, though to in¬ 
crease the chances of an improvement, it 
should be cross-impregnated, and when 
thoroughly ripened, let it be gathered 
and preserved till the following March 
or April; sown then in pans of light 
rich earth it speedily vegetates, and, in 
ordinary cases, the plants bloom in the 
following year. 
The other perennial species and their 
varieties are easily originated from seed 
treated in the manner described, and are 
afterwards increased by cuttings, as re¬ 
commended for pinks. They are all 
hardy, and in a border of good earth will 
grow and flower for many years. 
" DIGITALIS (Linn.) Nat. Or. Scro- 
phulariace<g% The tox-glove is an es¬ 
teemed ornament of the borders of the 
flower-garden; they prefer a rich loam- 
ing soil, with partial shade in summer, 
are readily increased by seeds or divi¬ 
sion of the old roots. 
DILLWYNIA (Smith.) Nat. Or¬ 
der Leguminosce. Handsome greenhouse 
plants, of neat habits of growth, free to 
flower, and easily cultivated in pots oi 
sandy peat; an airy part of the green¬ 
house should be allotted them in winter, 
and through the summer they will be 
benefited by being placed out of doors. 
It is essential, in order to produce hand¬ 
some plants, that the young shoots be 
frecpiently stopped while the plants are 
young, or they are liable to overgrow 
themselves. 
DIONiEA (Linn.) Nat. Qrd. Ce~ 
phcdotacecB. The only species 1). musci- 
pula, is a singular little plant whose 
leaves are armed with spines, and have 
an irritable power, for when touched, as 
by the alighting of a fly or other insect, 
the lobes of the leaf fold together, and 
they either transfix the trespasser, or he is 
made a prisoner beneath them. It should 
be grown in pots of peat and moss, stood 
in a pan of water, and covered with a 
bell-glass; the coolest end of a stove is 
the most appropriate position for it. 
DIOSMA (Linn.) Nat. Or. Rutacea. 
All the species of this genus are highly 
ornamental, their neat habit ol growing, 
the fragrance of their foliage, and the 
great number of flowers they produce,. 
render them particularly deserving of 
attention; they are easily cultivated in 
pots of sandy peat with the ordinary 
management of greenhouse plants. 
DIPLADENIxi ( De Candolle.) 
Nat. Ord. Apocynacea. Very beautiful 
stove-climbers, producing their large 
richly -coloured flowers freely upon com¬ 
paratively small plants. Turfy loam and 
peat appear to be the most appropriate 
soil, and if a gentle bottom heat can be 
allowed in the early part of the season, 
much benefit will be conferred upon the 
plants. 
DIS A (Linn.) Nat. Ord. Orclddacea. 
These really beautiful terrestrial Orchids 
are unfortunately difficult of manage¬ 
ment, or their beauty would.insure them 
universal adoption. In their native re¬ 
gions, at the Cape of Good Hope, they 
appear to grow in a soil composed chiefly 
of sand and decayed vegetable matter, 
and with us require a light soil of similar 
character, which must in addition be well 
drained; if placed in an ordinary pit, and 
protected from frost and wet in winter, 
“ the most reasonable prospect of a suc¬ 
cessful result will be insured ; they are
