GENUS RUBUS IN SUPPL. TO ENGLISH BOTANY 185 



from it considerably in the nearly unarmed panicle with few 

 suberect lower branches, as well as in the armature and 

 clothing of the stem" (" Journ. Bot.," 1892). No one seeing 

 the plant growing, especially as the season advances, would 

 connect it so closely with leucostachys. 



The " species " mentioned next in the Supplement, as R. 

 Grabowskii) Bab., not of Weihe, drops out of the list, until 

 the plant or plants which have been so referred can be 

 studied afresh. 



R. septorum, P. J. Miiller, which follows next, was the 

 name given provisionally to a Derbyshire plant which, being 

 shade-grown, proved rather puzzling. This, when R. durescens, 

 W. R. Linton, had been described, I referred to that species 

 and my naming was accepted by the Rev. W. R. Linton. 



R. Salteri, Bab., and var. calvatus (Lees). The notes on 

 these illustrate the impossibility of any one who has not 

 made a careful study of the brambles succeeding in solving 

 their perplexities. There is no doubt confusion among the 

 specimens that have been distributed, as Mr. N. E. Brown 

 remarks. The naming of specimens sent in to a club is 

 often revised afterwards, either by the same or another critic. 

 With regard to calvattts, some confusion was initiated by 

 Bloxam himself, the reputed describer of it, through his 

 accepting what we now know as R. Selnieri, Lindeb., from 

 the South of England as his calvatns. R. grains, Focke, 

 has also been referred to calvatus, before it was recognised 

 as a British species ; but both these differ considerably in 

 the fresh state from the Midland plant to which the name 

 calvatns belongs by right. R. Salteri, Bab., will be found 

 far removed from all these in the new " London Catalogue " 

 list, falling into a different group. 



R, podophyllus, P. J. Mull. The range of this plant is 

 now extended to nine vice -counties, and being a North 

 Midland rather than a Southern form, it should be looked 

 for in the South of Scotland. 



R. villicaulis, Koehler, var. adscitus, Bab. R. adscitus, 

 Genev., was so placed at a time when R. villicaulis, Koehl., 

 was generally misunderstood in this country. It is now 

 moved some way down the list, and regains an independent
