238 35. R. GUNTHERI. 



from the — wavy racliis forming an angle at each joining, 

 distantly, irregularly, and shortly branched panicle, leaves 

 with a thin coat cf felt beneath, and much more slender 

 prickles of R. Giintheri : also the nuts are exceedingly 

 different in shape. 



There hardly can be any doubt of the identity of our 

 plant and the R. Giintheri of the Ruhi Germanici. Arrhenius 

 considered it to be a state of R. glandulosus produced in 

 shade ; but we find that that species does not take this 

 form under such circumstances : also its panicle and arma- 

 ture are very different, and its leaves are considerably 

 dissimilar. It has much in common with R, hirtus, with 

 which Godron combines it. 



The R. Guntheri of Questier in Billot's Fl. exsic. (No. 2057) 

 appears to be R. rosaceus : my R. Guntheri has been sent 

 by him as a form of R. dumetorum. 



The wavy rachis, reflexed fruit-calyx, and usually 3-nate 

 leaves seems to distinguish R. Guntheri.
