 tose. Sepals without any leafy point, clothed with a whitish to- 

 mentum and a few setse.

Ohs. 1. The paler tint of the stem, much less strongly toothed 

 leaves and closer panicle appear to distinguish all the above forms, 

 which Dr. Bell Salter has combined under the name of R. Ra- 

 dula, from the R. rudis. Here also the prickles are not so nearly 

 equal, although the larger ones are usually almost equal, and 

 greatly exceed in size the under series which gradually merges in 

 short very thick aciculi and setse. 



Ohs. 2. The partial and general petioles, and also the midrib 

 of the leaves on the barren stems, are furnished with moderately 

 numerous rather slender but short hooked prickles, with a very 

 few short rigid points interspersed: but in the less frequent 

 forms referred above to R. pygrruEus and R. foliosus of the Ger- 

 man botanists, these rigid points become very numerous, and 

 together with the prickles vary so much in size as to merge in- 

 sensibly into each other. 



Ohs. 3. The plant referred above to R. foliosus (Weihe) difi"ers 

 slightly from the figure and description in the ' Rubi Germ.^ Its
