been many very beautiful additions of late years, including 

 the famed Marechal 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. ROSM STSTYL^: Koses 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 Eose, closely resembling the Dog Eose, 

 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 Monson's Eose, R. Monsonice, 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. arvensis, the Field Eose, is common all over Europe, in- 

 cluding 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 Eose of 

 English gardens, doubtless of hybrid origin, should be attached 

 to the Field Eose. 



This Eose, which has preserved most of the characters of R. 

 arvensis, 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 Eose Williams' s 

 Yellow Briar, sometimes classed with the Ayrshires, may it- 

 self be a mere hybrid. The Ayrshire Eoses are, from their 

 hardiness and rapid growth, admirably adapted for covering 

 old trees, pillars, buildings, etc. One of the best is Bennett
