and the flowers are very small, quite tiny, but often 
exquisite in colour and shape, generally produced 
in clusters and masses, and to distinguish them 
from their cousins of the climbing Polyantha group 
—are called by the National Rose Society pompons. 
Among the best are Gloire des Polyantha, Anna 
Marie de Montravel, EKugénie Lamesch, Léonie 
Lamesch, Perle d’Or, Petit Constant, Cecile Brunner 
Madame Phillipine Lambert. The majority of the 
new varieties are no doubt hybrids with the H.T.s 
and Teas. They are always in bloom, should be 
very lightly pruned, force well, and are best used 
as edgings except the taller growing varieties. 
The Macartney Rose (R. bracteata)—This species 
was introduced from China in 1795 by Lord 
Macartney. It is of vigorous growth, with bright 
glazed foliage, not very hardy, and best on a warm 
wall. The original was single, but Marie Leonida 
is double, sweet-scented, and generally a mass of 
bloom through the season in a warm situation. 
R. lucida, R. microphylla, and R. berberifolia are 
not hardy, but with shining foliage, and practically 
evergreen where well protected. ‘There are double 
and single forms. 
The Japanese Rose (R. rugosa).—These Roses are 
most distinct, the thickly spined wood and foliage 
being very fresh and pleasing, the single flowers 
large and fine, and the bright-red fruit handsome 
and striking. Originally the two principal varieties 
were the red and the white, the latter, very pure in 
colour, being generally the favourite, but there are 
now many hybrids of different shades, and more or 
less double. They do well on their own roots in 
good soil, for clumps, or a small ornamental hedge.
