782 ARBORETUM AND FRUTICETUM. PART III. 



increased vigour when their shoots are prostrate; and, if a large space is 

 required to be covered with them, they may be planted thin, and the ends 

 of the most vigorous shoots laid in the ground : in a few years, by these 

 means, acres of ground may be covered with them. On standards with 

 short stems they make very ornamental plants for lawns : if they grow 

 luxuriantly, the ends of the shoots will descend, and, if not shortened, will 

 produce, the following season, corymbs of flowers at every bud, forming a 

 dome-shaped mass having a fine effect." (Cat., p. 12.) They have, also, a 

 fine effect trained en pyramide against a slight wooden or wire frame. The 

 varieties of R. multiflora, 12 in number, are all distinguished by the fringed 

 stipules to their leaves, already described p. 774. The original species is 

 tender, requiring a south wall ; but several of the varieties which have been 

 produced by hybridisation are quite hardy. The Boursault roses, Mr. Rivers 

 observes, are all subvarieties of R. Boursault, which he calls a variety of R. 

 alpma, and the only one " thought worthy of cultivation." These roses may 

 be easily distinguished by their long, purplish-red, and nearly thornless shoots, 

 which are often 12 ft. or 15 ft. long in one season. There are 9 varieties. 

 Besides the above great divisions, there are several climbing roses, which 

 could not be classed under them. The most remarkable of these are, R. 

 Bankszce white and yellow, R. sinica, R. Clara, R. indica major, and the 

 climbing Provence. For the above remarks we are indebted to Mr. 

 Rivers, jun. 



Rosa indica, or China Roses, 70 sorts. " From six to eight months in the 

 year, the roses in this division form bright ornaments to our gardens : 

 many of the robust varieties make beautiful standards. They are all quite 

 hardy, and some of the varieties of the most brilliant colours : others of the 

 purest white. Some of the larger and more double flowers have a peculiar 

 delicate blush, unlike any other rose." 



~Rbsa indica odordta, or Tea-scented China Roses, 51 sorts. " These are 

 China roses having a strong odour of tea : they are seminal varieties of the 

 old blush tea-scented rose (R. indica odorata), and of R. ochroleuca, or the 

 yellow China rose. They are more delicate than those of the preceding sec- 

 _ion as to cold in winter, and also in their flowers, as they seem to require 

 the warm dewy nights of August and September to bring them to per- 

 fection. In hot weather, in June and July, they are very fleeting, as their 

 flowers are large and of a delicate texture, soon fading in sunny weather. 

 They require careful cultivation, and must have a raised border against a 

 south, south-east, or west wall. This border should be a compost of rotten 

 manure or leaves, light loam, and sand, equal parts, and raised about 18 in. 

 above the surface. When grown as low standards, they are surpassingly beau- 

 tiful : but they should be taken up in November, and their roots laid in 

 mould in a shed, as our sharp winters would injure them, so as to prevent 

 their blooming in perfection if left exposed." 



Miniature, or dwarf, China Roses, from Rosa Lawrenceana, 16 sorts. " Some 

 of these are known as fairy roses ; and they indeed deserve the appellation : 

 they are exceedingly well adapted for planting on rockwork ; their minute and 

 vivid flowers having an excellent effect in such situations. In the cool autum- 

 nal months, they bloom in great perfection." 



Noisette Roses, 66 sorts. " These have resulted from a happy intermixture 

 of the China rose with the old musk rose, and from it we have the annexed 

 numerous varieties, partaking in a pleasing manner of both parents : in many, 

 the clustered habit and peculiar fragrance of the musk rose prevails; in others, 

 the perfume and magnificent flowers of the tea-scented roses are apparent : 

 together forming a most elegant section. Some of the clusters of flowers are 

 so large as to have 60 to 80 in one corymb. The constant succession of 

 flowers, till the chills of November prevent the opening of the buds, makes 

 them highly interesting : they are all very hardy, and, as standards, seem to 

 show their varied characters with better effect than as dwarfs : they are also 

 well adapted for rose pillars, as their shoots are long and flexible."
