PREFACE TO THE TENTH 
EDITION 
The present edition is, with two exceptions, a reprint of the 
last. At the late Mrs Babington's request I i^ndertook to 
bring the names up to date, and to add a short appendix to 
include the most important additions to our knowledge of the 
British flora. 
It will be noticed that generic names whose authors did not 
employ the binominal system have been ignored. Such names 
should have exactly the same place in binominal nomenclature 
as those of Tournefort, etc., i.e.^ they should date for priority 
from the time when some binominalist author introduced 
them into the modern system. This departure from the 
Vienna code was made with Mrs Babington's consent, and 
will be found to lead to the retention of many recognised 
names. This principle was not adopted at Vienna, because 
M. Bri(iuet stated that it would cause many name-changes as 
a result of rejecting Adanson's work. M. Briquet's fears were 
unfounded. Adanson's names are all rejected here and the 
result is only one change, viz., Chamagrostis for Mibora, and 
the use of the latter was one of the first changes caused by 
the use of non -binominal works. Further, the majority of 
the generic name-changes made in accordance with the 
Vienna code are due to the use of non-binominalist names. 
It seems clear that the rule was created in misapprehension 
and should be revoked, since it leads to results opposite from 
its purpose
