ADDITIONS TO " IRISH TOPOGRAPHICAL 
BOTANY" IN 1908— 1912. 
BY R. LLOYD PRAEGER. 
It is five years since I brought up to date the Irish county 
records.^ In order to answer some queries as to recent 
extensions of range, I have now abstracted the pubhshed 
and unpubhshed notes of the intervening quinquennial 
period (up till the end of 19 12), and submit them herewith. 
The great activity in field-work which preceded the publica- 
tion of " Irish Topographical Botany," and which continued 
till the publication of the 1901-1905 supplement, ^ has died 
away, and some of our most energetic workers are engaged 
on other branches of science ; the distribution of Flowering 
Plants in Ireland is now tolerably thoroughly known — 
more thoroughly, for instance, as Mr. Colgan has shown, ^ 
than in Great Britain. The period since 1901 (when " Irish 
Top. Bot." was published) has been fruitful, not only in 
the adding of many rare plants to the floras of the different 
county-divisions, but in the filling-up of blanks in the 
distribution of the commoner species. In 1901 I published^ 
a list of " Plant Records Wanted," showing, to the extent 
of over one thousand items, the more conspicuous blanks 
existing in the county lists. It is satisfactory to record 
that the work of the intervening twe' ve years has wiped out 
more than one-third of these — 34 per cent., to be exact. 
During the same period, a total of about 1,140 new county 
records has been added to the distribution of Irish Flowering 
Plants as given in " Irish Topographical Botany."
