THE CULTIVATED ROSES, 



There are so many kinds of rose in cultivation that only 

 an expert can hope to know them all or to understand their re- 

 lationships. The sweet brier and the cinnamon rose are so com- 

 monly escaped that they are described in detail above. The 

 Gallic or French rose, Rosa gallica L. is a low bristly-glandular 

 plant with handsome dark green leaves and fine red flowers, 

 often semi-double, which has occasionally escaped from old 

 gardens to roadsides. The Scotch rose {Rosa spinosissima L.) 

 is often cultivated and may become naturalized near houses. 

 The finest of the double roses of garden and greenhouse are either 

 of the damask type {R. daniascena) or the India or China rose 

 (R. indica). The hybrid roses are of these two; the tea roses 

 are of the latter type. The eglantine rose (R. eglanteria) is an 

 old fashioned rose with fragrant foliage, resembling the sweet 

 brier. The Japanese rose {R. rugosa) is a more recent intro- 

 duction but rapidly gaining favor because of its rich foliage. 

 Recently the crimson and other ramblers and other clustered 

 roses of the multiiiora group have been given especial attention. 

 Since they are quite hardy and very attractive and new hybirds 

 are appearing each year, there is much to be hoped for them as 

 additions to the rose garden. 



THE THORNAPPLES. CRATAEGUS^ 



This group of plants is best developed in the limestone areas 

 of western Vermont, particularly about Lake Champlain and 

 its tributaries. Occasionally in the Green Mountains they reach 

 an altitude of 2,200 feet, and Crataegus Kennedyi Sarg. is known 

 only on the summit oi Willoughby Mountain, at about 2,500 feet. 



' Owing to the complexity of the various forms of thornapple, 

 especially in the Champlain valley, it has been necessary either to pass 

 by the group with only a general characterization, or else to make the 

 account more technical than is the balance of this bulletin. The above 

 carefully prepared account of the groups by Mr. Eggleston has been 

 accepted as the best method of treatment under these circumstances.
