Gnaphahum uhginosum, L. VI., VII. Sometimes it forms a loose 



sward on damp sandy-muddy shores. 

 Bidens cernua, L. V., VI. Distribution restricted, and plants usually 



scarce (fig. 78). 

 Senecio aquaticus, Hill. "I., II.," IV., V., VI, VII. Frequent about 



the shores of lowland lakes, but scarce in Area VII. 

 Serratula tinctoria, L. IV. This southern plant is well established in 



dry bushy places about the west shores of Loch Ken. 

 Cnicus palustris, Willcl. VII. In this Area it is frequently very 



abundant about marshy shores. In the other Areas, although a 



common plant, I have not seen it in sa\y abundance on the shores of 



the lakes. 



CAMPANULACE^. 



Lobelia Dortmanna, L. " I., III.," TV., V., VI., VII. Frequently very 

 abundant, but only in lochs that are more or less peat3\ Rare in 

 Area VII. 



GENTIANACE^. 



Menyanthes trifoliata, L. " I., II., III.," IV., V., VI., VII. This species 

 is ubiquitous, and thrives under all kinds of environmental 

 conditions. 



BORAGINACE^. 



Myosotis palustris. With., including M. scorpioides, M. strigulosa, M. 

 repens, and M. csespitosa. "I., II., III.," IV., V., VI., VIL The 

 characters distinguishing these are so interwoven that it is fre- 

 quently almost impossible to decide definitely upon tlie specimen 

 in hand. Although common, they are of but small importance as 

 a constituent of a loch flora ; I have therefore included the whole 

 in the aggregate M. palustris. They occur chiefly about lowland 

 non-peaty lakes. 



Symphytum officinale, L. Seldom found upon the shores of lochs, but 

 it does rarely so occur in Area VIL 



SCROPHULARIACEJi:. 



Scrophularia aquatica, L. " I.," IV., V. [VI. — J. M'A.]. Always scarce. 

 Scrophularia nodosa, L. IV. Abundant about the shores of Loch Ken 



and a few other places. A few plants occur sporadically about the 



lochs of Area I.
