S. oleraceuSf giving two varieties of it — laciniatus and 

 non-lacinia tus. 



Of Leontodon Taraxacum he mentions a variety 

 with narrow, very deeply laciniated leaves. He gives 

 L. palustre as a species, "on wet moors, not uncom- 

 mon," Avhich still remains true of it for habitat. 



Cichorium Intyhus, Succory, grew on the borders 

 of fields, but was very rare. It is found casually as 

 an escape from cultivation. 



For Serratula tinctoria, Saw-wort, his only station 

 is "Banks of the Clyde between Daldowie and Both- 

 well." This plant is undoubtedly an introduction, 

 and I am not aware of its having been observed of 

 recent years in any part of Clydesdale. 



The Welted Thistle (Carduus acanthoides), though 

 somewhat uncommon in the district, is abundant at 

 the present day in the immediate vicinity of the 

 city. What a glimpse of the diminutive Glasgow of 

 1813 is afforded by Hopkirk's station for this plant — 

 " abundantly in the waste ground beside St. George's 

 Church ! " Why, that is the very heart of the city 

 nowadays; and botanists have to go much further 

 afield for thistle-treasure. 



Carduus Marianus, the Milk Thistle, is of course 

 a garden-escape, found occasionally on rubbish and 

 near houses, just as in Hopkirk's time. He gives as 

 a station "on the rocks, Dumbarton Castle." 



Carduus tenuiflorus grew about Balvie, where 

 many introduced plants seem to have been found — 

 a circumstance to which I shall have again to refer. 

 This thistle is not known to occur now in any part 

 of Hopkirk's district, and had most likely been intro- 

 duced at Balvie. It may, however, be native about 

 Largs, where Hennedy states that it is found. 



The Melancholy Thistle (Carduus heterophyUus) is 

 entered in the list on the authority of Dr. Brown 

 as found at Daldowie. It is not now known to 

 occur there ; and from the fact that Hopkirk quotes 

 Dr. Brown, he had probably not found it there him- 

 self. Though it usvially grows in hilly districts,
