Praeger — On Types of Distribution in the Irish Flora. 27 



distribution sho-^s no marked aggregation in any part of the country. 

 It does not appear necessary to list those common plants, over 260 in 

 uumter, which are at present known to be universal in Ireland — 

 inhabitants of every botanical division. As might be expected, the 

 plants of universal distribution in this country are almost all of 

 "Watson's British type likewise ; it will be worth while to note the 

 exceptions. In the following list the "probably universal" species 

 which are not of British type are added to the "universal" plants, 

 and distinguished by an asterisk.
