I shall now briefly characterize those forms of British Rubi that 

 did uot come under my notice in the Malvern district. 



Subdiv. i. Rubi C^sii. 



R. Salteri, Bab. " Stem angled slightly hairy, prickles small, 

 leaflets elliptic acute, panicle compound." — Bell.-Salt. 



I am not acquainted with this bramble, except from a dubious 

 Cheshire specimen, sent me by the late Mr. S. E. Wilson, which 

 seems much like my R. sublustris ; and it is placed by Dr. Bell-Salter 

 himself next to corylifolius. It is said, however, to spread abun- 

 dantly by creeping stolons, which has hitherto been only observed of 

 the Idaean Rubi. It is stated to be " rare,"— its head-quarters the 

 Isle of Wight. With this, Dr. Bell-Salter has placed the following, 

 as a variety ; but, until better known, it may be advisable to describe 

 it separately. 



R. Balfourianus, Blox. Stem round or obtusely angular, clothed 

 with short, spreading, and accumbent hairs ; prickles irregularly scat- 

 tered, small, but strong and sharp ; petioles hairy ; leaves quinate, 

 very large, hairy above, densely pubescent beneath ; basal leaflets 

 subsessile, and slightly overlapping, central one cordate-ovate, dilated, 

 and often lobed, cuspidate, dentate-apiculate ; rachis hairy ; panicle 

 very broad, diffuse, hairy, and setose ; flowers on long setose pedi- 

 cels ; sepals broad, woolly, and setose, loosely investing the fruit. 

 In hedges, rare. 



This is a luxuriantly-developed bramble, distinguished by its very 

 large pubescent foliage, pale, but not white, beneath ; difi"used, 

 branched panicle ; and broad, woolly, setose calyces, loosely invest- 

 ing the fiuit. If really a state of R. Salteri, it is another instance of 

 the manner in which varieties sport into a monstrous appearance from 

 their normal forms, as shown in the common state of amplificatus, with 

 respect to R, Schlechtendahlii, and several others. In this, and many 

 gigantic Rubi, I have noticed that the stem often remains suberect 

 instead of arching, and, in this case, thickens at the top, becoming 

 very hairy there, and surrounded with a mass of dense, small prickles. 

 From the thickened part several other barren shoots branch off", or the 

 secondary shoots thicken in their turn, producing tertiaiy shoots ; till 

 the whole mass bends in some degree, or gets supported, the main 

 stem still remaining upright. From these suberect stems, luxuriant 

 flowering shoots proceed, often with monstrous, very compound 

 panicles. R. Balfourianus has been but rarely observed. My friend 

 the Rev. Andrew Bloxam gathered it near Rugby, Warwickshire. I
