pelled to admit them to be "rarce.'" A moment's glance at their figure 

 is sufficient to show that it has no affinity whatever with those species 

 amongst which they have arranged it ; whereas the form and nature 

 of the prickles, and the nature of the hairiness, at once associate it 

 with their R. pubescens. 



Concluding therefore that the R. diversifolius of Lindley and R. 

 vestitus of Weihe and Nees are identical forms, and only a variety of 

 R. leucostachys, it remained to choose by which name to designate 

 the variety. I have adopted that of Weihe and Nees, they having 

 noticed it anteriorly to Dr. Lindley ; though certainly the epithet of 

 rotundifolius, by which I had proposed in my own mind to call the 

 then supposed new species, when the variety first came under my no- 

 tice, would be a far more characteristic name than either of the above. 



I have received two specimens of this variety from the Botanical 

 Society of London ; one, collected in Shropshire, under the name of 

 R. villicaulis ; and the other from Worcestershire, by that of R. Ra- 

 dula — Ruhus Radula without a gland or a seta ! 



With respect to Mr. Lees' opinion that R. diversifolius is a form 

 deducible from R. caesius, inasmuch as he mistakes Lindley's plant, 

 considering it to be one with "abundance of glandulosity," * whereas 

 the author of the (supposed) species describes it as without glands, — 

 the conclusion of course falls to the ground. 



Ruhus carpinifolius (W. & N.) is one of the most remarkable and 

 beautiful of our British Rubi ; varying considerably according to the 

 situation in which it grows, and seeming to be generally not very well 

 understood : on which account I deem it necessary to give a rather 

 particular description of it. 



The mode of growth of the barren shoot is very similar to that 

 described of R. nitidus ( W. 8^ N.), being at first suberect, in which 

 condition it fi-equently remains, and also, when it does root, it is by 

 secondary growth after a temporary pause. It is therefore not truly 

 an arching species, though ranged with them. The stem is angular 

 and hairy, the hairs straight and spreading, and very apt to disappear 

 in drying. The prickles are very long, straight, and slightly deflect- 

 ed. The leaves are quinate ; leajiets narrow, variously serrated, but 

 the serratures very acute and remarkably directed forwards. The 

 panicle is variable as to its branching, but narrow and very generally 

 leafless ; the rachis is hairy, with a few glands occasionally. 



The ascending growth, the angular stem with hairs and no glands,
