 .*•/.., ami 'styles much slmrUr than stamens. ' The leaf-serration, though 

 perhaps a little variable, also seems to me much less wavy, and the 

 prickles less constantly falcate. I must add, however, that I am 

 at a loss to name any very definite characters by which to separate 

 this var. from the typical plant (so far as I understand that), 

 except its thicker yellower foliage, and (as they appear to me) its 

 larger and more loosely reflexed sep. At the same time the whole 

 plant looks softer, the fl. more showy, and the panicla-rachis more 

 conspicuously flexuose. In my Norden Heath specimen there is in 

 the term. It. a strong tendency to lobing or subdivision on one side, 

 of which I see no sign in my other British specimens or in those 

 I have from Denmark and Schleswig. Continental botanists in 

 general seem agreed in considering insularis a var. or subspecies of 

 11. viiUraulis ; but Areschoug himself, when he published his 

 description ("Some observations on the genus Rubus," p. 139), 

 placed it next after R. polyanthemos (R. pulcherrimns), and among 

 the Discolores, an arrangement in which none of us, I think, would 

 be disposed to follow him. 



The plant which has been long known to some of us as 

 " Bloxam's calvatus " now appears to me, as it does I believe to all 

 other botanists who have seen it growing, a very strongly marked 

 var. or subspecies. It seems best placed under R. viilicaulis as var. 

 calvatus (Blox.), though Bloxam himself did not confine that name 

 to this particular plant. It is easily separable from the other 

 varieties by the following characters : — 



Var. d. calvatus (Blox.). Prickles rather crowded and unequal,

remarkably oblong, with rather short point and cordate base. Pan. 

 very lony and la.e, with la/ye jnliaye, wavy prickly rachis, and sep. 



1 >erby, Staffs., Leic, Warw. Not yet observed in the extreme south, 

 the Devon plant thus named by the late Mr. Bloxam belonging 

 either to typical viilicaulis or to the so-called "south country 

 calvatus" distributed by me from the Bournemouth neighbourhood 

 (1886-1890), and described above as var. Selmeri. I may add that 

 in some of the Twycross (Leic.) specimens of Mr. Bloxam's own 

 gathering, and now in my herbarium, the special characters of this 

 var. are distinctly less marked than usual, and that such divergence 

 as there is favours the arrangement by which calvatus is placed 

 under R. viilicaulis. On the other hand, the Bev. W. H. Purchas has 

 long held, and I think with very good reason, that the Shirley and 

 Ednaston (Derb.) plant, which has been named R. melanoxylon 

 Muell. & Wirtg. by Dr. Focke, cannot possibly be kept specifically 

 distinct from calvatus, as it has all its most characteristic features, 

 and seems to differ only (as Mr. Purchas has pointed out) in being 

 more aciculate and glandular in st. and pan., and having a narrower 

 terra. It. Of this I have lately seen a Surrey specimen, gathered 

 by the Kev. E. F. Linton at Tilford, which is the most southern 

 locality yet known for it.
