segregate is to be met with elsewhere. 
Rubus, A good deal of interest attaches to the Bristol 
brambles. The number of recognized forms has greatly 
increased. Some of them are widely distributed, others are 
locally plentiful, and a few occur very sparingly. One plant 
from the vicinity of Wotton-under-Edge has been described 
and named as a new species (R. Bucknalli), and this has since 
been found in Herefordshire. Perhaps no family of plants 
is more clearly influenced by the geological nature of soil. 
But it may be sufficient for the purpose of this paper to give 
merely a complete hst of the local species arranged in natural 
order according to the latest view. R. idceus L., R. fissus
