DESKGLTSE ON CLASSIFICATION OF SPECIES OF ROSA. 309 



in height, having prickles mixed with gUmcluliferous setse, and pedun- 

 cles always glandulose ; it may by these characters be easily distinguished 

 from the Systylcc. The Cinnamomece, from their upriglit branches and 

 free styles cannot be confounded with the Systylce ; whilst their leaves, entire 

 calyx-divisions, the bracts on the peduncles, and their prickles, readily 

 separate the section from the Gallicancc. The PbnpinelUfoUm — which are 

 small undershrubs covered w^itli numerous prickles, leaves very small, 

 calyx-divisions entire persistent, and free styles — cannot be confounded 

 with the Sijstijlce. By their habit, the species of this section approach the 

 GallicaucB, from which they differ by their prickles, leaves, and calyx- 

 divisions. The AlpiiKB, somewhat resembling the Cinnamomece, are dis- 

 tinguished from it by their unarmed stems, peduncles without bracts, and 

 a habit and aspect different from all the others. The CanincB are ordin- 

 arily elevated shrubs, with flexuose branches, bending or straight, prickles 

 uniform, more or less robust, leaves glabrous or villose, but not tomentose 

 as in the TomentoscB, calyx-divisions pinnatifid ; by which diameters it may 

 easily be distinguished from the CinnamomeoB, Pimpinellifolia, and AJpince. 

 The Eglanteri(E are recognised by their yellow flowers ; a rare colour in the 

 genus Rosa, in which white and rose-colour predominate. The RubiginoscB, 

 with leaves always glandulose, bear a character by which they may be at 

 once distinguished from all the other sections. The Tomentosa by their 

 leaves and prickles are easily distinguished from both the Rahujinosce and 

 Canin(B. 



N.B, — In the following Synopsis the mark '-!< signifies that the species 

 has hitherto only been found in England ; f signifies that the 

 species is found both in France and England. The species with- 

 out mark are found in France but not in England.
