THE BRITISH RUBUS-LIST I/O 



It contains a list of British Rubi, revised and rearranged up to date 

 (April 1917) with vice-coinital census numbers and illustrative 

 notes — all prepared with a view to a new edition of the London 

 Catalogue. It is perhaps not necessary at present to reproduce the 

 list and notes in their entirety; hut some points may be made, in 

 supplement to the paper published last year in this Journal, p. 101. 



Mr. Rogers does not include Focke's variety plymeusis of R. 

 er/reqius Focke (see Journ. Bot. 191-1, p. 204) ; and the omission is 

 probably intentional, as 1 find no cover for this form in his Rubus 

 herbarium. R. opacus Focke is given specific rank at the head 

 of the SubrJiu mn ifolii. Under iucaroatas are placed var. b. rotundi- 

 folius Rogers, "the usual S. England form" of Handbook, pp. 27, 

 28 ; and var. c. subcarpinifolius Kogers, " the Upper Wye Valley 

 form, 1 ' ib. p. 28. R. Lindleiamis has a var. latifolius Rogers, the 

 Co. Down variety of Handbook, p. 28. R. chlorothyrsus Focke 

 finds no place in the list, and R. amphichloros P. J. Muel], though 

 included, is placed in square brackets. Instead of R. micaiis Gren. & 

 Grodr., we are to revert to the name R. adscitus Gene v. ; our plant is 

 certainly identical with Genevier's, whereas proof is at present 

 lacking that Lefv. & Mueller's hypoleucus is cpuite the same. Rogers's 

 var. mollissimus of hirtifolius stands. 



The most important changes are found in Groups XI. & XII. 

 After pallidus and var. are placed R. glare os as Rogers & Marshall, 

 with census 5 ; R. horridicaulisP. J. Muell. 7; R. rosaceus Wh. & N., 

 34, and var. b. Furcliasianus Rogers, 5; then R. scaler Wh. & N. 

 to R. foliosus Wh. & N. The Koehleriani run : — R. hystrLv, Wh. 

 & N., 5Q ?, var. b. bercheriensis Druce, 4, c. infecundvs Rogers, 42, 

 d. adornatus (P. J. Muell.), 21, e. Rowellii (Rogers), 4; then 

 R. hostilis, R.fusco-ater, and R. Koelderi onwards. Var. wiinuti- 

 fiorus (P. J. Muell.) is retained under R. hirtus without sign of 

 doubt; but c. cdlcareus Rogers MS., under R. corylifolius Sin., is 

 omitted.
