DISTRIBUTION OF RUBI IN GREAT BRITAIN 158 
Many of these are no doubt more or less local; but they are 
without a single exception 9 frequent in several wi ide ly-separated 
unties, while most of them are probably rather more generally 
distributed than has yet Sica me 
ition to the 54 commoner British brambles treated o 
Bised.s we have 113 i none of which have as yet been certainly 
found in more than 20 v.-c.’s. Nine of these are bay snown to occur 
in one v.-c. each; but over one-third of the are 104 are found 
in more than 10 v.-c.’s, and 19 of them in from 15 to 20 v.-c.’ 
These last are, as a rule, among our most mba tb species 
and subspecies, and within the next few years they will surely be 
found in other v 
The 9 forms biol thus far are known from only 1 v.-c. each 
are—R. durescens, mercicus, orthoclados, macranthelos, Lejeunet, 
nemorosus (Geney.), Durotrigum, tereticaulis, and rubriflorus, Of 
these, one, R. mercicus (once locally abundant near Birmingham), 
now seems in danger of extinction; while three more, macranthelos, 
Lejeunei, and tereticaulis, though all occurring in more than one 
ay seem abundant nowhere.
