13. R. THYRSOIDEUS. Ill 



In addition to the R. rohustus and R. speciosus, Muller's 

 R. coarctatus, R. sericophyllus, and perhaps some of the 

 other plants described in his Monograj^h, are included by ns 

 under R. thyrsoideus. 



Miiller informs us that the specimens in Wirtgen's Ruhi 

 numbered and named, 4 R. rhamni/olius, 5 and 33 R, can- 

 dicans, 39 R. villicaidis, 53 R. macroacanthus, 69, 70, 71, 

 72, and 73 R. thyrsoideus, belong to his R. speciosus: they 

 all appear to be forms of our R. thyrsoideus, where T also 

 place his R. inacroacanthus v. ohlonga (No. 10). Specimens 

 called R. fastigiatus by Mr Wahlberg and gathered near 

 Metz in France are almost exactly our R. thyrsoideus. 



The varieties o^R.fruticosus called y thyrsoideus, 8 macro- 

 acanthus, and € geminatus by Lees in Steele^s Handbook 

 belong to this species. 



I have not been able to obtain access to the original 

 Flora von Schlesien of Wimmer, and quote it on the au- 

 thority of later editions. Doubtless the name adopted from 

 some manuscript of Weihe, and used by Keichenbach in his 

 Fl. excursoria, is older than that which is now universally 

 employed for this species; but Arrhenius seems to me to 

 have shown good reason for following Wimmer, rather than 

 lleichenbach, in this matter.
