2. Downy Rose. Rosa villosa, Linn. (Fig. 324.) 

 (Eng. Bot. t. 583. B. mollis, Eng. Bot. t. 2459, and B. tomentosa, Sm.) 



In its ordinary state, this is distin- 

 guished from the downy varieties of the 

 dog B. chiefly by the globular fruit, more 

 or less covered with small, fine pric- 

 kles, which are seldom entirely wanting. 

 It is usually more erect and bushy, 

 the prickles of the stem straight or 

 but slightly curved ; the leaflets softly 

 downy on both sides, and almost always 

 doubly toothed. Calyx-segments long, 

 and often expanded near the top, some- 

 times all entire, sometimes, as in the dog 

 B., some of them more or less pinnately 

 lobed. Flowers white or pale-pink. 



In hedges and thickets, in Europe and 

 western Asia, and chiefly in the north, 

 or in the mountain districts of the south. Generally distributed over 

 Britain, but chiefly in Scotland, northern and w r estern England, and 

 Ireland. Fl. early summer. The B. scabriuscula, Eng. Bot. t. 1896, 

 B. kibernica, t. 2196, B. Sabini, Suppl. t. 2594, and B. Doniana, 

 Suppl. t. 2601, appear to be slight varieties of this species, to which 

 belongs also the Apple Bose (B. pomifera), from continental Europe.

3. Sweetbriar Rose, 

 (Eng. Bot. t. 991 



Rosa rubiginosa, Linn. (Fig. 325.) 



B. micrantha, t. 2490, and B. sepium, Suppl. 

 t. 2653. Sweetbriar.) 



Very nearly allied to the dog B., but 

 in its typical state, as cultivated in our 

 gardens, easily recognized by the aroma- 

 tic scent of the foliage when rubbed. 

 This proceeds from small glands, co- 

 piously scattered on the leafstalks and 

 under side and edges of the leaflets, often 

 giving the foliage a rusty hue. In the 

 wild state the scent is often very faint, 

 although the glands are still numerous. 

 The plant is usually more slender than 

 the dog B., the prickles curved or hooked, 

 often intermixed with glandular hairs ; 

 the leaflets rather small, and almost al-
