t wig-s are occasionally unarmed, but have more usually binate uncinate 

 prickles near the base of the leaves, and others scattered, varying in 

 size and curvature. Leaflets flat, or often concave, pale bright green, 

 more or less hairy, ovate, or broadly elliptical, or often almost round, 

 occasionally narrower and more pointed, but scarcely tapering to the 

 base ; sprinkled copiously beneath, on the edges and on the petioles, 

 with fragrant viscid glands, which are found also on the backs and 

 edges of the stipules. Peduncles, and often the calyx-tube, beset with 

 seta}, of which those at the base of the latter are usually larger; seg- 

 ments setose and glandulose, with a lengthened leafy point and narrow 

 lanceolate pinna, spreading almost at right angles, with gland-pointed 

 teeth. Petals deep pink, equal to the calyx, or rather shorter. Styles 

 included, slightly hairy ; stigma scarcely protuberant. Fruit changing 

 first to yellow then to orange-red, its substance thin, scarcely pulpy, 

 •and almost insipid when ripe ; when in bunches the primordial is pear- 

 shaped, the secondary obovate, but less tapering at the base ; the others 

 elliptical. The fragrance of the leaves is compared to that of ripe 

 apples. Borrer. Mr. Templeton was of opinion that our wild sweet- 

 briar is different from the plant sold under that name in the nur- 

 series.
