tose. Sepals without any leafy point, clothed with a whitish to- 
mentum and a few setze.

Obs. 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 setz. 
Obs. 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 pomts interspersed: but in the less frequent 
forms referred above to R. pygmaeus 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. 
Obs. 8. The plant referred above to R. foliosus (Weihe) differs 
slightly from the figure and description in the ‘ Rubi Germ.’ Its
