Usually a tall shrub, with elongate, arching stems and branches ; prickles 
equal, generally stout, falcate or uncinate. Leaves septenate ; leaflets simply or 
doubly toothed, glabrous, the midrib beneath sometimes glandular, more rarely 
the secondary nerves, but never the whole lower surface. Stipules adnate, with free 
auricles. Peduncles solitary or few, bracteate at the base, smooth or sometimes 
glandular. Styles free, short, more or less hispid ; disc conspicuous. Fruit 
globose, ovoid, urceolate or ellipsoid. Sepals pinnate, reflexed after flowering, 
deciduous, more rarely ascending and subpersistent. 
Rosa canina, as here defined, is a comprehensive species, including 
a large number of forms, at least a hundred of which have been given 
specific rank. Consequently almost every variety of habit, size, colour
