112 ICOSANDRIA POL YGYNI A . 



" The buds are peculiarly handsome when sufficiently ex- 

 panded to shew the bright red tints with which the outer 

 edge of the snow-white petals are marked." Sometimes 

 the flowers are entirely white ; and a variety with them 

 scarcely one-half their usual size, grows abundantly at 

 the sides of the road between Ancroft and Barmoor. 

 Probably a variety of R. tomentosa. 



* * * Branches without bristles. Prickles hooked, compressed. Styles 

 distinct. 



4. R. rubiginosa^ fruit obovate, bristly towards the base ; calyx 

 pinnate ; prickles hooked, compressed, with smaller, straighter 

 ones interspersed ; leaflets elliptical, doubly serrated, hairy, 

 clothed beneath with rusty-coloured glands. Sweet Briar. 



Hob. Hedges about Scremmerston and Broomhouse, but 

 not certainly wild. July. 



5. R. sarmentacea, fruit broadly elliptical, naked ; flower-stalks 

 aggregate, smooth or minutely bristly ; calyx strongly pinnate ; 

 prickles hooked; leaflets ovate, doubly serrated, very smooth. 

 Trailing Rose* 



Hab. Hedges and deans, frequent. June, July. 



It will, I think, depend upon the value which may be at- 

 tached to the character afforded by the doubly serrated 

 leaves, whether we will consider this species distinct from 

 R. canina, or not. I cannot perceive any other difference 

 between them. Flowers pale pink. 



6. R. dumetorum, fruit elliptical, smooth, as tall as the brae- 

 teas ; flower-stalks aggregate, smooth ; calyx copiously pinnate, 

 somewhat cut ; prickles numerously scattered, hooked ; leaflets 

 simply serrated, hairy on both sides. Thicket Rose. (Eng. Fl. 

 ii. 392.) 



Hab. "Deans and hedges not rare in this neighbourhood. 

 Side of the road between New Farm and the Old Lam- 

 berton Toll. Below Lamberton Shields. On banks 

 between Middleton and Langley Ford. June, July. 



A branching shrub, 3 or 4 feet high. Branches brownish, 

 smooth, or blistered, round, with equal hooked prickles. 

 Two of these are generally placed at the base of each leaf, 

 one a little below the other, and there is often a third ; 

 the base is much dilated. Leaflets 5 or 7, ovate, acute,
