R. RUGOSA (_syn R. ferox of Bot. Reg._), a Japanese species, and its
variety R. rugosa alba, are beautiful shrubs that have proved themselves
perfectly hardy and well suited for extensive culture in this country.
They are of stiff, shrubby habit, about 4 feet high, and with branches
thickly clothed with spines becoming brown with age. Leaflets oval in
shape, deep green, with the upper surface rough to the touch, the under
sides densely tomentose. Flowers single, fully 3 inches in diameter, the
petals of good substance, and white or rose-coloured. The fruit is
large, larger than that of perhaps any other rose, and of a bright red
when fully ripe. In so far as beauty of fruit is concerned, this Rose
has certainly no rival, and whether for the rockwork or open border it
must be classed amongst the most useful and beautiful of hardy shrubs.
R. rugosa is a capital hedge plant, and being a true species it is
readily propagated from seed. R. rugosa Kamtschatika is a deep-red
flowered form with deciduous spines.

R. SEMPERVIRENS.--Evergreen Rose. South Europe and India, 1529. A
