very interesting to contrast its scarcity in Clydes- 

 dale with its profusion in the Forth district. 



The whole of the district Ruhiaceoe are entered in 

 his list except Galium idiginosum^ which is not fre- 

 qvient near Glasgow. G. Mollugo and G. boreale he 

 gives as not common. The stations mentioned are 

 those where they are still known to occur. The 

 former is probably not indigenous in the district, 

 while the latter is undoubtedly a native. 



In connection with the Plantains, he points out 

 that Plantago viaritiTna is by no means confined to 

 the sea-coast, quoting Ure's inland station for it, 

 *' on the roadside near to the avenue into White- 

 moss." Lightfoot says of this plant : " It grows not 

 only by the seashores, but even to the summits 

 of the highest mountains in the highlands." This 

 peculiarity it has along with many other plants that 

 are usually considered inhabitants of shores. The 

 climate of certain elevated districts is evidently 

 favourable to their growth, as is that near the sea, 

 and this is probably mainly owing to the moisture 

 of the atmosphere and the plenteous rains. 



Centunculns viiniinus is not now known to occur 

 " in a marsh near Langside," quoted by Hopkirk on 

 the authority of Dr. Brown, or " in Kenmuir bog." 

 It is still found, however, somewhat beyond the 

 boundaries of Hopkirk's district, in Cumbrae and 

 Arran. 



Epimediiim alpinum — clearly an introduction — grew 

 at that time abundantly about the ruins of the old 

 Castle of Mugdock. 



For Wall Pellitory (Parietaria officinalis), he gives 

 two stations — one on the authority of Ure, " on an 

 old wall on the roadside between Rutherglen and 

 Farme ;" and the other " on the ruins of Both well 

 Castle abundantly." At the latter station it still 

 holds its own ; and this is now, I believe, the only 

 place in Clydesdale where the plant can have any 

 claim to be considered indigenous. When we reflect, 

 however, on the number of plants that are found on
