Differs from lutetiana only by its aciculate peduncles. 

 Not unfrequent, especially in the south of England. A form 

 with sepals glandular on the back, from the Pass of Lanrick, 



{Bloxam\).

R. DUMALis, var. glandulosa, Gren. Jura^ p. 215. 



Bears the same relation to dumalis that the last does to lute- 



tiana. 



Not uncommon. Extreme specimens with the calyx-tube 

 prickly as well as the peduncle, and sepals glandulous on the 

 back, gathered in Somersetshire near Bridgewater (T. Clark I) 

 and Weston-super-mare {Woods !), and in Devonshire (Briggs !). 

 i2. psilopTiyllay Rau, Enum. p, 101, only differs from this by its 

 hairy petioles.

R. tJMBELLATA, Li6er/, in Lej. FL Spa, ii, p. 313. 



The representative of urbica in this group. As gathered by Mr. 

 Borrer in Surrey and Mr. Briggs near Plymouth this has nume- 

 rous flowers in a cluster, and flat leaves broadly rounded at the 

 base with moderately open serrations ; but the commoner form is, 

 like ordinary urbica, less robust, with narrower more sharply 

 toothed leaves. 



Var. CiESiA (Smith), 



Woods. Linn. Trans, xii. p. 212, 



Herb. 7S; Borrer, Brit. Flora, edit. 3, p. 242 [ex parte). 



Very near the last, the leaves grey-green, softly hairy beneath 

 and slightly so on the upper surface, the teeth slightly compound. 

 Petiole slightly glanduloso-setose. Stipules and bracts pubes- 

 cent on the back. Sepals glandular on the back.
