Native. Paludal, Inundatal. According to the localities 

 on record, it would appear that this species finds an earlier 

 northern limit than B. cemua, at least on the eastern side 

 of Scotland. The present is omitted from the Floras of 

 Moray, Aberdeen, Forfar, Edinburgh, and Bei*wick, that is, 

 all the eastern Floras. By the Flora Glottiana, however, 

 it would seem that B. tripartita occurs more frequently 

 about Glasgovr ; and while Professor Balfour mentions 

 Cantire only for B. cemua, he names Arran, Cantire, and 

 Islay, for B. tripartita. According to the Catalogue printed 

 for the Botanical Society of Edinburgh, both the species 

 do occur about the Firth of Forth ; and they are marked as 

 equally rare. Probably the names are occasionally misap- 

 plied ; the leaves varying much in fomi and division.

Native. Paludal, Inundatal, &c. Most frequently seen 

 along the banks of streams, or in hedges by water ; and no 

 term has been adopted for expressing the river-bank pre- 

 ference, because very few (if any) plants appear restricted 

 to such situations. The river-bank plants, indeed, are in- 

 teimediate between the paludal and inundatal ; being more 

 or less flooded in the winter season, although the water may
