Hedges near Cork ; Mr. J. Drummond. Fl. June, July. T? .— 

 Scarcely stoloniferous. " Often ten or twelve feet high, vaguely 

 branched, and with strong arched shoots. Prickles on the stem, not 

 much dilated in general at the base, compressed, and often much en- 

 larged in the lower part, so as to be almost triangular, with a straight 

 point, or a short, hooked beak ; those on the ramuli usually in substi- 

 pular pairs. Leaflets more generally five than seven, carinate, lanceo- 

 late or elliptical, bright green and shining, or rarely opaque above, 

 paler and slightly hairy beneath ; serratures tolerably regular ; peti- 

 oles downy, with curved prickles, with or without glands. Peduncle 

 rather long, with numerous glands or short setae, a few of which are 

 rarely found on the tube of the calyx. Calyx-segments broad and 

 short, with a tapering point and linear-lanceolate pinnce, entire or with 

 a few gland-tipped teeth. Petals longer than the calyx, pink, some- 

 times white. Column of styles usually protruded, but variable in 

 length ; occasionally quite included ; stigmas forming a conical head. 

 Fruit oblong, or sometimes globular, pulpy and orange-red when ripe, 

 flavoured like that of R. arvensis. The habit of the plant, when vi- 

 gorous, of all our wild Roses, most resembles that of R. canina. The 

 prickles on young strong shoots are generally crimson or rich dark 

 purple, and the young foliage tinged with reddish brown. The flowers 

 often form large bunches, and are generally of a peculiarly pleasant 

 pink, with the stamens and the base of the petals of a glowing orange 

 tint." Borrer. 



16. R. arvensis, Huds. Trailing Dog Rose. Prickles un- 

 cinate, those of the ramuli feeble ; leaves simply serrated, deci- 

 duous, (glaucescent beneath), their disk eglandulose ; calyx- 

 segments sparingly pinnate, deciduous ; styles united, hairless ; 

 shoots trailing. Br. Fl. 1. p. 241. E. Fl. v. ii. p. 397. E.

Plentiful in hedges and bushy places near Dublin. Near Ballyna- 

 hinch, County of Down ; Mr. Templeton. Fl. June, July. T? . — 

 Bush scarcely a yard high when unsupported, with trailing shoots, run- 

 ning to a great length, especially when growing in hedges, with much 

 divided, entangled, feeble ramuli, which occasionally produce rugged 

 excrescences and take root. Pricldes numerous, not much dilated at 

 the base, uncinate, those on strong shoots compressedly conical, with a 

 straight or curved point ; those on the ramuli few and scattered, small, 

 more or less curved. Leaflets thin, nearly flat, coarsely serrated, dull
