R. Wahlbergii, Arrh. Stem angular, excessively armed with 

 unequal prickles and setae ; leaves pedate-quinate, with overlapping 

 leaflets, hairy on both sides ; panicle branched, long, leafy and setose ; 

 sepals patent glandular ; " drupes glaucous with silky hairs." Banks 

 of Leigh Brook near Bridges-stone Mill. 



R. suUustris. Stem angular, smooth (setae rare), with distant 

 prickles ; leaves quinate, smooth above, green with soft pubescence 

 beneath, last pair of leaflets sessile, overlapping ; panicle corymbose, 

 downy, leafy below ; sepals reflex in fruit. Hedges in the low 

 country. 



This is the " corylifoHus " of Smith, confounded by Weihe and 

 Nees with their dumetorum. The flowers are generally white, ap- 

 pearing early, but some varieties have them purple ; in others the 

 leaves assume a monstrous aspect, the central leaflet divided. The 

 most remarkable deviation from the type is my var. coenosus (Steele's 

 ' Handbook'), in which the stem is hairy, covered with sessile white 

 glands, and thus often begrimed with dust; the panicle much 

 branched, with numerous pale glands, and downy corymbose branches. 



ii. RuBi Glandulosi, Barren stem arching or procumbent, more 

 or less covered with aciculi and setae. 



R. tenui-nrmatus, Lees. Stem angular, sparingly setose ; prickles 

 scattered, slender, very weak, nearly equal ; leaves pedate or quinate, 

 the lowest pair of leaflets sessile, central one ovate or cordate-ovate, 

 acuminate, all sharply serrate, downy or glaucous beneath ; panicle 

 with distant leafy branches, hairy and armed with long descending 

 weak prickles, many setae, and a few pale aciculi, crowded at the 

 summit ; the sepals tomentose, patent after flowering. In hedges 

 and thickets about Great Malvern. 



This characteristic species has been confounded with the dubious 

 Schleicheri of Rub. Germ., but is certainly not the Schleicheri of 

 Leighton's Fascic, neither, I think, of W. and N. It approaches 

 some varieties of dumetorum, but may always be distinguished by its 

 weak prickles, that are broken at the slightest touch, its involute 

 sepals, and scattered leafy panicle. 



R. Guntheri, W. and N. Stem prostrate, angular, clothed with 

 long hairs and numerous setae, aciculi, and slender prickles ; leaves 

 ternate, quaternate, and quinate, smooth above, pilose beneath, the 

 central leaflet obovate acuminate ; panicle narrow, flexuous, subra- 

 cemose, hairy and glandular, with a few weak prickles ; petals nar- 

 row ; sepals elongated, closely reflex in fruit. Crow's-nest Wood in 

 profusion, but a local species.
