Hardy Ornamental Flowering Trees and Shrubs by A. D. Webster

R. VISCOSA (_syn R. glutinosa_).--Clammy Locust. North America, 1797.
This is a small-growing tree, and readily distinguished by the clammy
bark of the younger shoots. Flowers in short racemes, and of a beautiful
rose-pink, but varying a good deal in depth of tint. It is a valuable
species for ornamental planting, and flowers well even in a young state.

Few soils would seem to come amiss to the Acacias, but observations
made in many parts of the country conclusively prove that the finest
specimens are growing on light, rich loam overlying a bed of gravel.
They are propagated from seed, by layers, or by grafting.


ROSA.

ROSA ALBA.--This is a supposed garden hybrid between R. canina and R.
gallica (1597). It has very glaucous foliage, and large flowers, which
vary according to the variety from pure white to rose.

R. REPENS (_syn R. arvensis_).--Field Rose. Europe (Britain). This
species bears white flowers that are produced in threes or fours, rarely
solitary. The whole plant is usually of weak and straggling growth, with
shining leaves.

R. BRACTEATA (Macartney Rose), R. PALUSTRIS (Marsh Rose), and R.
MICROPHYLLA (small-leaved Rose), belong to that section supplied with
floral leaves or bracts, and shaggy fruit. They are of compact growth,
with neat, shining leaves, the flowers of the first-mentioned being rose
or carmine, and those of the other two pure white.

R. CANINA.--Dog Rose. Our native Roses have now been reduced to five
