DRY DUL 
Drimia, Jacquin. From drimys, acrid ; the juice of 
the roots is so acrid as EiTcause inflammation when 
applied to the skin. Linn. 6, Or. 1, Nat. Or. Li~ 
liacicE. An ornamental genus, when the plants 
are in flower; they require a mixture of sa^dy 
loam and leaf mould, or peat soil. When not in a 
growing state, they require but little water, and 
when potted just before they begin to grow, they 
will flower freely. Synonyme : 1. D. lanceasfolia,

DrIm vs, From drimys, acrid; the juice of 
the root causes inflammation when applied to the 
skin. Linn. 13, Or. 4, Nat. Or. WinteracecE. Valu- 
able trees, from twelve to forty feet high, requiring 
a mixture of loam, peat, and sand ; ripened cut- 
tings would probably root, if planted in sand, under 
a glass. The winter bark, which resembles that 
of cinnamon, is the produce of D. Winteri. Syno-

Drosera. From droseros, dewy; the plants are beset 
with glandular hairs, which makes them appear as 
if covered with dew. Linn. 5, Or. 5, Nat. Or. 
Droseracex. This is a most singular and beautifixl 
genus of plants, whose leaves are ornamented with 
red, glandular hairs, discharging from their ends a 
drop of viscid acrid juice. These hairs are so irri- 
table as to contract when touched, imprisoning 
insects, after the manner of Dionaa Miucipula. In 
their native state, they are found growing on mossy 
turfy bogs. The best way to grow them, is to plant 
them in small pots, about three parts full of peat 
earth, and some sphagnum planted on it ; the plants 
should then be planted in the moss, and the pots 
placed in pans of water, and even then, the hardy 
species grow best in the ^eenhouse. They are all 
increased by seeds, which should be allowed to sow 
themselves. Synoriyme: 1. D. intermedia.

Drummon’dia, Deeandolle. Named after Mr. Thomas 
Drummond, a well-known naturalist, and Jealous 
collector of plants, chiefly in the United States ; he 
died at Havannah, in March, 1835. Linn. 5, Or. 2, 
Nat. Or. Saxifragacex. This is a very pretty little 
plant, well adapted for the front of flower-borders, 
or to grow on rock work. It grows most luxuriantly 
in peat, though it succeeds in any light soil ; divi-

UmbelliferoE. A hardy annual, the seeds of which

Dryandra, R. Brorvn. In honour of J.onasDryander, 
a distinguished Swedish botanist. Linn. 4, Or. 
1, Nat. Or. Proteaceae. A splendid genus of plants, 
nearly related to Banksia. All the species thrive 
well in an equal mixture of turfy loam, peat, and 
sand. The pots require to be well drained, and 
the potsherds broken very small, because the 
roots are fond of running among them. Cuttings 
taken off at a joint, in August or September, and 
planted in sand. Without shortening the leaves, 
will readily root, if placed on a gentle hotbed, 
(but not plunged,) under a glass; but they must 
be covered, so as the frost cannot injure them. 
As soon as rooted, they must be potted off, as the 
sand would injure the roots if they were too long 
in it ; after being potted off, they should be placed 
in a close frame, and hardened to the air by degrees. 
The cuttings will do equally well if put in early 
in spring, just as they are beginning to push out 
young wolod.

Silenacece. This beautiful little plant is well 
adapted for ornamenting rock-work, in which

may be increased by cuttings, planted in sand, 
under a glass, or by seeds, sown in an equal mix- 
ture of loam, peat, and sand, and when the plants 
get of sufficient size, they ought to be planted on 
the top of rock-work, where they must not be 
suffered to get dry till they are well established.
