In hedges, thickets, and the borders of fields, chiefly in the mid- 

 land and southern counties. Mr. Woods remarks that it is rare 

 in the mountainous districts. Common in Norfolk. 



Shrub. July. 



A bush about 4 or 5 feet high, much more when supported, send- 

 ing forth abundance of trailing, glaucous, often mahogany- 

 coloured, arching branches, many feet in length. Prickles all 

 scattered, not in pairs, strongly hooked, smaller than those of 

 R. canina. Leajlets 5, rarely 7, elliptic-oblong, acute, simply, 

 though sometimes unequally, serrated, generally smooth on both 

 sides ; glaucous beneath, where the ribs are often hairy. 

 Foolsfalks prickly, finely hairy as well as minutely glandular. 

 Stipulas linear, acute, narrow, glandular at the margins. Brac- 

 teas similar, linear-lanceolate. Fl. rarely solitary, generally 

 from 3 to 5 together, rather concave, slightly scented, white 

 and very elegant ; the buds frequently blush-coloured. Flower- 

 stalks often dark red, rough with numerous short glandular 

 bristles. Tube of the calyx elliptic-oblong, glaucous, partly 

 reddish, smooth, rarely glandular ; segments smooth or some- 

 what glandular, pinnate, with lanceolate smooth leaflets. Flo- 

 ral receptacle convex, but not conical, nor so prominent as in 

 R. systyla, though the styles are much longer, united, as in that, 

 into a stout furrowed column, destitute of hairs, which is not 

 the case with any other British Rose, except the last, and 

 crowned by the smooth stigmas, crowded, and partly combined, 

 into a round head. Fruit of a dark blood-colour, usually, as 

 far as I have seen, globular and smooth. Mr. Woods describes 

 it as in general elliptic-oblong, at least where the stalks are 

 aggregfvte. He highly commends its flavour, as well as that of 

 R. systyla. 



I have never perceived any specific diff"erence between R. arvensis 

 and the Ayrshire Rose, now so frequently cultivated. The latter 

 has been proved by Mr. Sabine's accurate inquiries, see Tr. of 

 Hurt. Soc. V. 4. 4i)6, to be of exotic origin, and therefore does
