THOMAS HOPKIRK OF DALBETH. 233 



Poterium Sanguisoi^ba, which is not mentioned by 

 Kennedy, he records for "dry sandy banks near the 

 Clyde, Dalbeth." It does not now seem to occur 

 there, and has no claim to be considered native 

 though occasionally found. Specimens have recently 

 been gathered on a railway-cutting near Old Kil- 

 patrick. 



With regard to the Willows, of which his list 

 includes ten kinds, the critical determination of 

 species has been so fully developed since his time 

 that it would serve little purpose to institute a 

 comparison. 



He records the whole of the Juncacece still known 

 to occur about Glasgow. 



Of the Grasses, Kennedy gives seventeen species 

 more than Kopkirk; but most of these are found 

 on the shores of the Firth, or on mountains not 

 included in Koi)kirk's district. One grass — Lepturus 

 filiformis — which occurs abundantly between Greenock 

 and Gourock, is not mentioned either by Kopkirk or 

 Kennedy. Among those which grow in the district 

 embraced by the Flora Glottiana, and which are not 

 mentioned, are : Melica riutans (rare), Kocleria cristata 

 (rare), Avena fatua (a weed), Arena strigosa (a weed), 

 Poa aqiiafica (which has perhai)s extended into the 

 district since his time), Poa maritima (occurring on 

 the coast at the very limits of his district), Bi^omus 

 secalinus (not indigenous, and probably introduced 

 with seed), and one or two others. One species 

 mentioned by him — Panicum sanguinale — of which 

 he found only one i)lant, though common on the 

 Continent, is not a native of Britain. 



Of Carices he enumerates twenty-eight species. 

 Kis recurra, cwspitosa, and stricta seem to be glauca, 

 Scop., rulgaris, Fries, and aquatilis, WahL, var. 

 TVatsoni, respectively. Ke gives depaiipei^ata as very 

 rare, but occurring in a small wood near Balvie. 

 Kere it may have been introduced, as George Don 

 had it in cultivation in his garden in Forfar. Balvie 

 was evidently at this time a centre about which
