Floristik und Systematik der Phanerogamen. 347 



Certain plants of wide distribution in Ireland are eharacterised by 

 being absent from deiinite areas; such constitute smaller groups, Anti- 

 Lagenian (absent from area of Lagenian type), Anti - Ultonian, Anti- 

 Central etc. 



The last few pages are devoted to a discussion of probably or cer- 

 tainly introduced plants. Aliens are generally marked by a discontinuous 

 ränge, a large number being widely spread, whilst others fall in with 

 vari'ous Types of Distribution, which is probably the effect of soil or 

 climate. Most are marginal, but both Lagnian and Mumonian types in- 

 clude a considerable number of aliens. The great Leinster anticline plays 

 an important part in the distribution of Irish plants and forms a marked 

 phytological boundary, a point already demonstrated in the previous 

 pages. — The paper terminates with a comparison between Watson's 

 and the author's types of distribution and a brief discussion of the causes 

 which may have led to the present distribution of the Flora.
