THOMAS HOPKIRK OF DAL-BETH. 229 



there is every probability that Dr. Brown did really 

 find this plant at Daldowie. I have observed it, 

 along with Galuiin horeale^ in wild places by the 

 banks of streams that flow into the Avon, and there 

 it is undoubtedly native. As these localities are in 

 the hilly district drained by the Clyde, and at no 

 great distance from Daldowie, there is every likeli- 

 hood that it formerly grew in that nearer station. 

 This receives support from the occurrence of Galium 

 horeale about Carmyle and elsewhere in that neigh- 

 bourhood. 



He records the two species of Biclens — tripartita 

 and cernua — for the district. The former he states 

 to be frequent, and the latter rare. Neither of 

 them now appears to be frequently met with in the 

 vicinity of Glasgow, though both are indigenous. 

 Perhaps the extension of the system of agricultural 

 drainage, by curtailing the area of ^Yet ground and 

 reducing the number of stagnant i)ools and open 

 ditches, may have rendered Clydesdale less suitable 

 for the growth of these marsh plants. 



Tansy (Tanacetum vidgarej seems to have been 

 then much commoner than now. It has probably 

 become rarer, owing to its cultivation in gardens 

 having been almost entirely given up. 



Hemp -Agrimony (Eupatoriuin cannahinuin) ap- 

 pears to be found near Glasgow in only one station 

 as at that time, though so frequent in its occurrence 

 along the coast. 



Mugwort (Ai^temisia vulgaris) is still frequent in 

 hedges and waste ground. 



Of the CudAveeds, Filago mluivia was then found 

 plentifully on the Tollcross sandhills, and F. 

 ger7nanica appears to have been observed occasion- 

 ally, as in the gravel-pits at Bothwell. 



For Senecio viscosus he merely quotes lire's 

 station, "at Rawhead," and he siDeaks of it as rare. 

 Neither does Patrick seem to have been acquainted 

 with any other station. Hennedy gives two additional 

 localities for it; but calls it "not common." This
