NOTES ON ENGLISH EUBI. 131 



the living plant in England, but numerous dried English speci- 

 mens. 



Cont. distrib. Denmark, N.W. and C. Germany, N. France. 



24. E. pulcherrimus Neuman. R. polyanthemos Lindeg. — Mr. 

 Baker puts it under R. umbrosus Aut. Anglor. as a glandular variety. 

 This view may be correct, as the differences seem to be of little 

 importance. I know, however, no intermediate forms. I have not 

 seen the living plant, but I have received dried specimens from 

 different parts of England. 



Cont. distrib. S. Sweden, Denmark, Germany (very local). 



25. E. macrothyrsos Lange. — Mr. Griffith and Mr. Bailey have 

 sent me specimens of this beautiful bramble from N.W. Wales. 



Cont. distrib. Very local in N.W. Germany (Holstein, Hartz 

 Mount.) and N. France (Oise, Seine Inf. ; see Assoc. Eubol. 430, 631). 



26. E. pyramidalis Kaltnb. — In general appearance it resembles 

 R. villicaulis (calvatus), but it is distinguished by smaller prickles, a 

 very soft, nearly velvety under side of the leaves, a dense and 

 always glandular panicle, &c. I have seen a good deal of dried 

 English specimens. 



Cont. distrib. S. Sweden, Denmark, N. and W. Germany, 

 Belgium, N. France. 



27. E. vestitus W. et N. R. leucostachys Schleich. — In such 

 genera as Rubus it is nearly impossible to follow in every case the 

 rules of priority. We cannot choose the first name, if its meaning 

 is not quite clear and correct. The first description of a bramble 

 is often very incomplete or erroneous, or it combines different forms 

 or separates allied ones. The name of tl leucostachys '' or "white 

 spike" shows that the author did not include the ordinary pink- 

 flowering form. On the other hand, the description of R. vestitus 

 given by Weihe et Nees is very accurate ; the authors have studied 

 the influence of soil and moisture upon the plant, they have pointed 

 out under what circumstances this species will produce pink or 

 white flowers, orbicular or elliptic leaflets with a white or a green 

 under surface. Therefore, I think we shall do better to prefer the 

 name R. vestitus, published a few months later, than leucostachys, for 

 the same reasons as we prefer R. suberectus to Nessensis and rosaceus 

 to heter acanthus. I have seen R. vestitus at many places in S. 

 England. 



Cont. distrib. Denmark, W. Germany, Belgium, Switzerland, 

 Austria (very local), France. 



V. Stems arcuate-prostrate, bearing prickles of nearly equal size and 

 glandular seta, or small })rickles. No intermediate aciculi and 

 bristles. 

 a. Glandular seta, scattered or confined to the lower part of the 

 barren stem. 



28. E. Bor^anus Genev. — Not rare around Plymouth, where I 

 saw it with Mr. Briggs at different places (Egg Buckland, Bick- 

 leigh, &c). 



Cont. distrib. W. France.
