stones, remains of old walls, &c.— 
is of great use for laying at the- 
bottom of a flower-bed or border in 
an open garden in which bulbs are 
to be grown. A similar bed has also 
been found very useful for growing 
Dahlias, as they are very liable to 
be injured by stagnant moisture. 
Ro‘z1a.— Rubidcee.—The Mad- 
der. The perennial species, which 
are not remarkable for their beauty, 
are quite hardy, and will grow in 
any soil. There are also some half- 
hardy shrubs, which are worth cul- 
tivating in a greenhouse for their 
flowers, which are generally yellow. 
A red dye is derived from the roots 
of all the species, but principally 
from those of R. tinctdrium, which 
is cultivated as a field-plant in the 
south of Europe. 
Ru‘sus.—Rosacee.—The Bram- 
ble. There are but few ornamental 
species of this very extensive genus. 
R. odordtus, the flowering Rasp- 
berry, with reddish flowers, and R. 
nootkanus, the Nootka Sound Brain- 
ble, with large white flowers, both 
kinds being sweet-scented, are the 
mostornamental ‘To these may be 
added the double-flowered common 
Bramble (R_ fruticdsus, var. pom- 
ponius) and R. spectabilis, the Cali- 
fornian Bramble, with fragrant dark | 
purple flowers, and dark yellow fruit. 
All the Brambles are very hardy, 
but very short-lived ; their stems 
dying down every second year, like 
those of the common Raspberry 
(Ribus ide‘us). They all send up 
numerous suckers, by which they 
are propagated ; and they all delight 
in a moist soil and shaded situation; 
though they will not thrive exactly 
under the drip of trees. 
Rupse’cKx1a.—Composite.—Very 
showy perennial, biennial, and an- 
nual plants, which should be grown 
in light rich soil. They attain a

very large size, and are therefore 
only suitable to large gardens. They 
are all hardy, and of the easiest cul- 
ture of their respective kinds. 
Rue.—See Ro‘ra. 
Rue’tuia.— Acanthicee. — Her- 
baceous plants with pretty tube- 
shaped blue flowers. Some of the 
species require a stove, and others 
a greenhouse ; but they should all 
be grown in light rich soil, and are 
propagated by cuttings. 
Ru’mex.—Polygéneze.—The Dock. 
Most of the species are British weeds, 
but some few are grown for their 
flowers. ‘They like a very deep and 
rich soil. 
Ru'scus. — Smilacinee. — The 
Butcher’s Broom. Very curious 
evergreen shrubs, mest of which 
bear their flowers and fruit on their 
leaves. All the species prefer shady 
situations under the drip of trees, 
where but few other plants will grow; 
and they are all readily increased by 
suckers from their roots, which they 
throw up in abundance. One of the 
kinds is sometimes called the Alex- 
andrian Laurel. 
Russe'L1a. — Scrophularinee. — 
R. juncea is a very elegant stove- 
plant, with slender rush-like bran- 
ches, and scarlet tube-like flowers. 
It should be grown in light rich soil, 
and abundantly supplied with water 
while in a growing state. It is pro- 
pagated by cuttings, struck in heat. 
Rou'va.—_ Rutacee.—The Rue. R. 
gravéolensis a well-known glaucous- 
leaved plant, having a very unplea- 
sant smell, and a bitter taste. ‘he 
leaves are nearly blue, and from 
their peculiar colour sometimes pro- 
duce a good effect in a shrubbery. 
The flowers are yellowish. The 
plant will grow in any soil or situ- 
ation.
