been many very beautiful additions of late years, including 
the famed Jaréchal Niel. Some of the varieties of this class 
also are in bloom during the whole Summer and Autumn, 
which, coupled with the beauty of their flowers, causes them to 
be much sought after. 
IX. Rosa Sysriz#: Roses with confluent styles—This is 
the only distinctive character, but the leaves are often persis- 
tent, which may be considered as a secondary character. We 
have here :— 
R. systyla, the Hill Rose, closely resembling the Dog Rose, 
from which it differs mainly in its confluent styles, and also 
in having usually more numerous-flowered corymbs, and the 
rather more persistent though always deciduous foliage. This 
bush is common in England and Northern France. By some 
authors it is united with the following. 
Lady Mouson’s Rose, R. Monsonic, is attached to this as a 
variety, perhaps hybrid; but some authors have called it a 
distinct species. It was found in a hedgerow in England to- 
wards the end of the last century. This pretty somewhat 
dwarf variety is still preserved in the collections of some 
English amateurs. 
R. arvénsis, the Field Rose, is common all over Europe, in- 
eluding Britain. It is distinguished from the preceding by its 
more creeping shoots, unequal prickles, and by its leaves being 
glaucous beneath. The leaves consist of 5 to 7 small flat oval 
toothed leaflets. The flowers are solitary or clustered, small, 
single, scented, white slightly tinged with yellow towards the 
centre. The calyx-tube is obovoid and glabrous, and the 
' “mature fruit nearly round and scarlet. 
It has been clearly demonstrated by the botanist Sims first, 
and subsequently by Dr. Lindley, that the Ayrshire Rose of 
English gardens, doubtless of hybrid origin, should be attached 
to the Field Rose. 
This Rose, which has preserved most of the characters of R: 
arvénsis, and particularly its confluent styles and perfect 
hardiness, has given birth to several varieties pretty widely 
spread in gardens, with double or semi-double white, pink, 
or bright carmine odoriferous flowers. The Rose Williams’s 
Fellow Briar, sometimes classed with the Ayrshires, may it- 
self be a mere hybrid. The Ayrshire Roses are, from their 
hardiness and rapid growth, admirably adapted for covering 
old trees, pillars, buildings, etc. One of the best is Bennet’s
