as common then as now, though Hopkirk applies 

 the somewhat limited term "frequent" to each. G. 

 Tetrahit is classed as a "native or colonist," and G. 

 versicolor as a " colonist," by Hewett C. Watson ; but 

 I am doubtful whether versicolor has not quite as 

 good a claim to be considered truly native as the 

 other. It is equally common in this district, and, 

 as Watson himself observes, is "perhaps truly a 

 boreal variety of Tet7^ahit" It is interesting to note 

 that these weeds have not lost their hold since 

 Hopkirk's time, as so many others have done. It is 

 quite clear that thqy are not dependent on human 

 sowing like Venus' Comb, the Corn Rose, and some 

 others. 



The three Woundworts (Stachys) had the same 

 distribution as at present. 



Black-Horehound (Ballota nigra), which seems to 

 have disappeared from the neighbourhood of Glas- 

 gow, was then sometimes found on waste ground, 

 and Hopkirk gives as a station, "about Cathcart 

 Castle." It was probably grown a good deal owing 

 to its reputation in rustic medicine. 



Motherwort (Leonurus Cardiaca) was merely a 

 casual then as now. 



Calamintha Clinopodium was only occasionally met 

 with. It is found in truly wild places, and is un- 

 doubtedly a native, though by no means common. 



Origaiiiiin vulgare (Marjoram) he gives as " in 

 bushy places and at hedge bottoms frequent." It is 

 now rarely met with, and this is probably accounted 

 for by its having been supplanted in cottage 

 gardens by more brilliant and odoriferous plants. 



Besides the typical Wild Thyme he gives three 

 varieties, two of which — the one with white flowers, 

 and the hirsute one — we now consider mere forms. 

 The other — ^^flore amplo" — is perhaps the variety 

 cha^ncedy^ys. 



For the rare Bartsia viscosa, so distinctly a western 

 plant, he records two stations : " Banks of the Clyde 

 at Ardoch Cottage. Abundantly behind the inn,
