■which "we shall presently return. For the rest, excepting their 

 frequency in Antrim, they decrease from S.E. to N.W., reaching their 

 minimum in Sligo, Leitrim, Monaghan, and Tyrone. It may be 

 pointed out that the group embraces a number of maritime plants, and 

 therefore the maritime divisions are necessarily slightly richer in 

 species than divisions situated inland. 



3. Scottish Type : " Species chiefly seen in !N". orN. M. Britain." 

 — This type is the opposite of the last. With headquarters well up in 

 Scotland, the species range southward in diminishing numbers. They 

 are the northern plants of Britain. 



As characteristic examples of the Scottish type "Watson cites — 



Empetrum nigrum. , Trientalis europsea. 



Eubus saxatilis. Ligusticum scoticum. 



Trollius europaeus. Mertensia maritima. 



Geranium sylvaticum. 



Of these, Trientalis is absent from Ireland ; of the remaining six, 

 three are confined to the north. This and the succeeding groups being 

 much smaller than the British and English types, we will call in the 

 full strength of the group, whether the species be of pui-e or qualified 

 type, in order to strengthen the features indicated by their distribution. 

 The Scottish type in Ireland is represented by 50 species, or less than 

 half of the British total —
