DRY STOVE. 
more than an inch in diameter, 
which gardeners call crocks or pot- 
sherds, as from their porous nature 
they form reservoirs of moisture, 
which will prevent the plants from 
ever becoming too dry. Cinders, 
on the contrary, are to be preferred 
for delicate or succulent-rocted 
plants, as the crocks retain so much 
moisture as to be injurious to the 
roots of these plants. The Austra- 
lian and Cape shrubs, should have 
their pots drained with two or three 
layers of crocks, as these will retain 
sufficient moisture to prevent the 
roots from withering, which even 
an hour or two of perfect dryness 
would occasion them to do. 
Drititinc.—Sowing seeds singly 
in furrows made in straight lines; 
a mode of sowing very useful in 
culinary crops, but seldom practis- 
ed with flowers, which scarcely 
ever require to be hoed up. 
Dro’sera. — Droserdcee.— The 
Sundew. British, American, and 
Australian plants, with hairy leaves 
and curious flowers, which require 
to be grown in moss, or peat, or 
heath-mould, kept moist, and dur- 
ing the heat of the day covered 
with a bell-glass. The hairs on the 
leaves support drops of water in the 
hottest weather, and being very ir- 
ritable, close on any insect that 
may chance to touch them, like 
those of Dione‘a musc?pula, Venus’s 
Fly-trap, the leaf bending over the 
insect, and holding it in prison. 
The Italian liqueur called Rossoglia 
is said to take its name from one of 
the species being used in its compo- 
sition. ‘The Australian species from 
the Swan River, seeds of which 
have been introduced by Capt. 
Mangles, promise to be very beau- 
tiful. All the kinds of Drosera ap- 
pear to be very short-lived; and 
probably will not live longer than 
three or four years, whatever care 
may be taken of them. 
DUVAUA. 
plant structure, for tropical plants 
which do not require a moist heat, 
such as some of the kinds of Cacti, 
cr other succulent plants. The 
temperature of the dry stove should 
not be less, even in winter, than 
between 55° and 65°; but in sum- 
mer it may be from 10° to 20° 
higher. The plants are placed on 
shelves or benches; and they are 
grown in pots of sandy peat, or 
very porous soil, thoroughly drain- 
ed, which in general should be kept 
much drier than the soil of plants, 
either in the greenhouse, or in the 
moist or bark stove. The plants 
generally grown in a dry stove are 
the different species of Melocacti, 
Epiphyllum, Cereus, Euphorbia, 
Stapelia, Agave, Mesembryanthe- 
mum, Crassula, Sedum, Sempervi- 
vum, Larochea, and several sorts 
of bulbs, such as Lachenalia, Oxa- 
lis, &e. 
Dume Cane.—Calddium segui- 
num.—A kind of Arum, requiring a 
bark stove, and more curious than 
beautiful. 
Duvau's.— Anacardidcee, or Te- 
rebinthacee.—Chilian shrubs, which 
prove nearly hardy in the climate 
of London. They were called 
A'myris by Cavanilles, and Schinus 
by Ortega, both professors of bo- 
tany at Madrid; and they are oc- 
casionally found under these names 
in gardens and nurseries. The 
commonest kind, D. depéndens, 
Dec.,* (A’myris poly'gama, Cav.,) 
withstood the winter of 1837-8, in 
the Horticultural, Society’s Garden, 
with very little protection. The 
leaves of plants of this genus, if 
thrown upon water, will start and 
jump about in a very extraordinary 
manner; and they smell strongly 
of tarpentine. The plants should 
be grown in a light dry soil, and 
trained against a south wall, where 
they can be protected by a thatched 
coping during winter. The flowers, 
Dry Srove.— A hothouse, or| which are white, are produced in
