British Wild Flowers and Trees 231 



R. villosa, which in various forms makes a large bush, with 

 erect or arching branches, very hairy leaves and densely 

 glandular sepals. It is distinguished from the last-mentioned 

 by its larger size and equal prickles, and from R. canina by 

 its straight prickles. Under it we have R. tomentosa, with a 

 large pale pink flower, and R. mollissima, with a smaller, 

 deeper-coloured flower. The succeeding species is R. involuta, 

 under which are numerous kinds, small and erect, with short 

 branches and crowded prickles, passing into bristles. Among 

 them we may note R. Wilsoni, with bright red flowers, and 

 R. Sabini, with ample foliage and pale pink flowers. Next 

 is our fragrant R. rubiginosa, the sweet Briar, which, however, 

 is less fragrant, as it approaches R. canina and R. villosa. 

 Near to this species we may mention R. macrantha and R. 

 sepium, both of which have rather pretty flowers, though 

 they are somewhat small. R. hibernica is the next species 

 to refer to, and it is intermediate between R. spinosissima 

 and R. canina, though most like the latter. It is small and 

 erect, with short, sometimes arching branches and erect 

 globose naked fruit. It is figured with pale pink flowers. 

 Rosa canina is the familiar Dog Rose, of which the varieties 

 are very numerous. It has long arching branches, with stout 

 hooked prickles, having a thickened base, and in the common 

 form is the strongest growing of British Roses. It is often 

 very beautiful, and, all things considered, some of the best 

 results may no doubt be got from this species. R. caesia 

 and R. incana, belonging to this species, have glaucous leaves. 

 The foliage of R. Bakeri is very pretty, and R. dumalis is a 

 fine tall kind, but the varieties of this species are so numerous, 

 that it is difficult to specify. Our last species is R. arvensis, 

 known from R. canina by the union of the styles into a long 

 slender column, that species having the styles free. There
