The garden varieties of Delplüniiim, as given
in the catalogues of nurserymen, are some of
them exceedingly beautifnl. A few may be
named—d e l i c a t i i v i , cardioiMaliim, Hen dcrsoni,
nnagnificiim, grandifloriim, máximum,
formbsum, Montmtrency^ Mooreámon.
DÉLTA-LEAVED, shaped like the Greek A.
DELTOIDES, triangular.
DEMITIUM, Persoon. From a diminutive of
clema, a bundle ; in reference to the mode of
growth. Linn. 24, Or. 9, Nat. Or. Botrytaccce.
An extremely minute species of Fungi, of a
bluish colour, found on the stems of herbs in
autumn—articulatiim.
DEMULCENT, having the property of softening
anything.
DENDRÓBIUM, Swartz, Prom dcndron, a tree,
and hios, life; in the places of their natural
growth, the species are generally found upon
trees. Linn. 20, Or. 1, Nut. Or. Orchidacece.
ISTo orchidaceous plants contribute more to the
gaiety of the stove than the species of this
splendid genus. L). nobile, clirysdntlmm^ Qihsoni,
firahriatum, densifldrum, and many
others, are equalled by few, and certainly not
surpassed, in the beauty of their flowers, by
any other orchidaccous plants ; and if the following
directions be attended to, they will be
found very easy of culture :—All orchidaceous
plants require (to cultivate them successfully),
a season of growth, a season of rest, and a season
for flowering ; all of which should coincide,
as much as possible, with the corresponding
seasons of those parts of the globe which they
so profusely inhabit; and the species of this
genus should especially bo subjected to a
change of treatment assimilating as much as
D E N
possible to that before mentioned, without
which, they will never flower in perfection.
I n India, three seasons only are known ; the
hot, or dry season, which is succeeded by the
rainy season, and the cold, or winter season.
I n the hot season, all, or the greater part, of
the plants belonging to this genus produce
their flowers ; in the rainy season, they make
their shoots ; and during the cold season, they
have a period of repose. The difl"erent seasons
bemg so well known, it is very easy to imitate
them in oin' hothouses, and by attending to
these simple rules, we should be enabled to
flower the species of this more abundantly
than those of any other orchidaceous genus,
besides which, they might be easily induced
to flower in this country ab any season of the
year. I), clirysdnthum, Pierardi, and some
others grow well when fasten3d singly on
pieces of wood, and treated as is recommended
under Burling Iònia ; but they all succeed well
when 2>otted in very turfy peat, raised above
the pot, in the same way as is recommended
in potting Btanhòpeas. A strong moist heat
is indispensable in the growing season, when
they may be frequently slightly syringed overhead.
They will be found to succeed best in
a warmer part of the house than the Stanliòpeas
require. They are propagated by detaching
one or more of the stems while in a dormant
state, taking care not to injure the roots, and
potting it carefully in turfy peat soil, and not
much raised above the pot, which must be
carefully drained; the pot should then be
plunged in a gentle bottom heat, where the
plant will speedily produce new shoots. Synonymes
