SQ Plants observed in North Wales. 



plant The rocks were every where covered with a profusion 

 of Helianthemum canum (Cistus marifolius of English botany, 

 although not of Linnaeus), which grows intermixed with the 

 common H. vulgare. There are several other fine ranges of 

 rocks above the village, which produce Chrysocoma Linosyris 

 and other rarities; but the heavy rain, and the circumstance of 

 our having a long stage to go after getting back to Conway, 

 prevented my exploring them. In the salt marshes by the 

 river side, near Conway, Cochleariadanica? grows abundantly. 

 As we approached Holywell, ^iola lutea appeared common 

 by the road side, and the heaps of rubbish round the lead 

 mines were completely covered with Arenaria verna. 



June 13.. From Holywell to Chester and Liverpool we 

 observed no plants worth naming. 



June 15. We travelled from Liverpool to Bolton, by the 

 railway, at a speed which almost precluded any botanical 

 observation. I nevertheless noticed a patch of the white- 

 flowered variety of TWfolium pratense, and on Chat Moss 

 abundance of Osmunda regalis. 



June 16. At Egerton, near Bolton, we gathered Faccinium 

 Oxycoccus (Oxycoccus paliistris Pursh), 22quisetum sylvati- 

 cum, Polypodium Z)ryopteris and Phegopteris, with a white- 

 flowered variety of .Lychnis Flos cuculi. 



June 21. I spent this day with my excellent friend, 

 Mr. Wilson, at Warrington. A pond in his garden was 

 completely a sheet of white with the flowers of ^41isma natans, 

 originally introduced from the lake of Llanberis. With it 

 were also growing Callitricrie autumnalis, and Z21atine hexandra 

 and Hydropiper. He has succeeded in cultivating that rare 

 moss Schistostega pennata, on the inner surface of a stone 

 trough, from which the light is excluded. In the afternoon 

 we visited Woolston Moss, an extensive morass, producing 

 many good plants. Among those we gathered were Andro- 

 meda ^olifolia, iZubus suberectus and nitidus? Drosera 

 anglica, Aspidium rigidum, Utricularia minor, //ypnum 

 fluitans and Caenomyce coccifera. Hipparchia Davus was 

 flying about in considerable number ; but I was unable to 

 meet with Carabus nitens, which Mr. Wilson informed me 

 sometimes occurs there. 



June 24. At One Ash Grange, near Bakewell, I was 

 much pleased to find a station for i?umex alpinus, which, as 

 a British plant, has, I think, hitherto been confined to Scot- 

 land. It is perhaps a doubtful native of this country. The 

 limestone rocks in all the dales about Money Ash, are com- 

 pletely covered with Galium pusillum, and those which are 

 shady and moist with Gfeum rival e and Cistopteris dentata.
