DOT DRA 
DRA DRE 
Dothidea, Fries. Derived from dothien, a tubercle> 
and eidos, similar. Linn. 24, Or. 9, Nat. Or. Fungi. 
Mostly dark species, growing upon stems of grass, 
and leaves of trees — dlnia, betullnd, Geranii, Hi- 
mdntid, Ptiridis, ribesia, Robertiand, Ulmi. 
Dots — may be pellucid, resinous, or hairy. 
Douglasia. Named by Dr. Lindley, some years ago, 
in compliment to Mr. Douglas, whose zeal in col- 
lecting seeds and plants, and whose untimely end, 
have richly earned for him a niche in the long 
gallery of departed science. Linn. 5, Or. 1, Nat. 
Or. Primulacece. This is a very beautiful, but 
scarce, little plant, growing pretty freely in peat 
and sand, and ripening its seed in small quantity. 
Mr. Douglas transmitted the seed, from whi^ 
this interesting plant was raised, from the Rocky 
Mountains, where he first found it among the 
snow, and afterwards from California,

Dove's-foot, see Geranium mOlle. 
Down, soft, short hairs. 
Downy- villous, covered with long soft hairs. 
Downy-pubescent, soft, short down, closely pressed 
to the surface. 
Draba, Decandolle. From drabe, acrid, biting ; taste 
of the leaves. Linn. 15, Nat. Or. Cruciferce. Some 
of the species of this genus are very pretty, being 
well adapted for ornamenting rock- work, or grow- 
ing in pots, among other alpine plants. A mixture 
of loam and peat suits them best, and they increase 
withlacility, either by dividing at the root, or by 
seeds. Synonymes: 1. D. aizoides. 2. D. incana. 3.

Drac.®:na, Linn. From drakaina, a female dragon; 
the inspissated juice becomes a powder, like the 
dragon’s-blood. Linn. 6, Or. 1, Nat. Or. Liliacece. 
Very ornamental trees, well worthy of being cul- 
tivated in every collection of stove plants. They 
thrive well in a light, loamy soil ; large cuttings 
root freely by being stuck in the tan, provided 
there be a strong heat. In Java, the root of D. 
terminalis is considered a valuable medicine in 
dysenteric affections. The substance called Gum 
Dragon, so well known in medicine, is the juice of 
D. Draco. Synonyme: 1. D. marginala.

Dracockphalum, Linn. From drakon, a dragon, and 
kephale, head ; the appearance of the heads of the 
flowers. Linn. 15, Or. 1, Nat. Or. Labiata. Most 
of the species are ornamental, and as such, they 
deserve a place in every garden. They succeed 
well in common garden soil. Some of the tender 
perennial kinds require the protection of a frame 
in winter, and, on that account, they ought to be 
grown in pots ; they increase readily by dividing 
at the roots. The annual kinds merely require 
sowing in a rich, light soil, in the open ground, 
where they will flower beautifully. Synonyme ; 1 .
