stated that the original Noisette was an accidental cross between this and 

 Rosa indica. 



Rosa multiflora, the blackberry rose, so called from the great resem- 

 blance of its clusters of flowers to those of the blackberry, is another of 

 this type. It is a native of China, Japan, and Corea. It is one of the 

 parents of several summer-flowering hybrids, such as Crimson Rambler. 

 Crossed with Rasa indica, it has produced the class of perpetual flowering 

 dwarf miniature roses known as polyantha. Rosa sempervircns is known 

 as the evergreen rose, not because it is strictly evergreen, but because 

 it holds its leaves 'longer than most roses do. It is a native of middle 

 Europe, Greece and the Balearic Islands. It is not as hardy in this 

 latitude as some of its relatives. Rosa Wichuraiaua is a native of China 

 and Japan. It was introduced into cultivation about 1887. It is espe- 

 cially useful for covering masses of rocks and is perfectly hardy. One 

 must not forget Jersey Beauty when thinking of this rose. Rosa Banksiae, 

 a native of southern China, was named in honor of Lady Banks. Un- 

 fortunately this requires the protection of a greenhouse in northern lati- 

 tudes. There is a yellow and a white form. 



Passing to the canina group, w^e have Rosa canina itself, the dog rose, 

 a native of Europe and temperate Asia. It is sometimes found growing 

 as an introduction in the eastern part of the United States. Rosa riibi- 

 ginosa is another species of this same group, a native of Europe. This 

 is familiar to you all as the sweet-brier, receiving this name from the 

 pleasant odor exhaled by the foliage, especially when crushed. 



Among the cinnamon group we have Rosa cinnaniomea itself, the 

 cinnamon rose, found wild in Europe and Asia. Rosa blanda, at home 

 in the eastern United States, is one of our charming little roses; and 

 Rosa humilis, of the same region, is especially happy growing among 

 rocks. Rosa rugosa, of Asia, is a sturdy representative and one perhaps 

 destined to play an important part in the future in hybrid work. 



The swamp rose, Rosa Carolina, delights the eye when forming groups 

 in its favorite haunts, the shores of lakes and streams or in swamps. 



The Burnet or single Scotch rose, Rosa spinosissima. is a European resi- 

 dent. There are many forms of this, one known as the variety altaica. 



Rosa httca — a native of western Asia, Italy and Austria — is known as 

 the Austrian brier, and has been in cultivation as far back as 1586. 



Rosa hracteata, the Macartney rose, wild in southern China and Formosa, 

 unfortunately is not hardy in the north, and from its range this is to be 

 expected. It is just as unfortunate, however, as it is a lovely rose. It 

 has become naturalized in Florida and Louisiana. 



Rosa laevigata, the Cherokee rose, is a native of China, Formosa and 

 Japan. This is practically the range of Rosa bracteata, so of course it 

 is not hardy in the north. It is, however, extensively naturalized in the 

 south, and I recall with delight the beauties of this charming rose as I 

 saw it growing wild on the fences in Florida. 



We usually think of the rose leaf as being made up of three or more
