.37. R. FOLTOSUS. 24' 5 



structi :" very different from the extremely hairy and abun- 

 dantly setose sepals of our plant and of E. exsecatus; in 

 the latter the hair is rather less abundant, and the setse are 

 more numerous. 



This plant is allied to R. humifusus: but the serration of 

 the leaves is peculiar, and the ovate-attenuate spinous sepals 

 are very unlike those of that species. The shape of the 

 terminal leaflet also is remarkable. 



Should it ultimately be determined that this is not the 

 R.Joliosus (Weihe), as seems quite possible, the name given 

 by Miiller must probably be adopted for it. 



I believe that Mr Bloxam has not published any account 

 of this plant, nor do I know if it is abundant at Hartshill 

 wood, from whence I possess two excellent specimens, or at 

 the other station near Atherstone. Mr Briggs tells me that 

 it is found in several places near Plymouth.
