DOUBTFULLY NATIVE WESTERNESS PLANTS 181 



(CNICUS PALUSTRIS, Willd., is native, and is very common in wet 

 pastures, by sides of streams, in glens, on wet rocks, in woods, 

 and by ditches and roadsides. It follows cattle to the moors, 

 on which it is not permanent, and spreads up the sides of 

 valleys as well as along their bases on soil which is not peaty; 

 but it usually occurs there only as isolated plants, following I 

 believe the footsteps of cattle and sheep.) 



LAPSANA COMMUNIS, Z., is a denizen, I believe, being generally 

 distributed but not common. I have taken special interest in 

 the distribution of this plant for some time, and have satisfied 

 myself that it is not a native of this district. Although without 

 pappus, it spreads quickly in new suitable stations. Generally 

 near cultivation it grows on some sea cliffs ; but in suspicious 

 localities, e.g. in copses near cultivation, or if at some distance 

 from cultivation, other denizens are found with or near it. 

 One station is in a remote glen ; but it is close to the spot 

 where the proprietor of that district occasionally has picnics ; 

 and it grows nowhere else in the glen. Another remote station 

 is a wet rock on the side of a wooded hill ; but on looking 

 round I found an old cattle track with Plantago major on it 

 about twenty yards off, and following this came to a disused 

 cattle shelter, not readily recognisable, in which were nettles 

 and Cnicus lanceolatus. The plant grows at only one other place 

 in this wood, and this is close to another cattle track. 



TARAXACUM OFFICINALE, Web., is a denizen probably, but is rather 

 common on roadsides and on neighbouring banks and sandy 

 shores. It grows occasionally on sandy shores at some distance 

 from cultivation, where it has a permanent hold unaffected by 

 man's agency. 



SONCHUS ASPER, Hoffm., is frequent. A small form grows on sea 

 cliffs, which, I think, is native it grows in similar places in 

 Eigg and Skye. An increasing species through cultivation. 



(FRAXINUS EXCELSIOR, Z., is native, being common in glens and copses.) 



MYOSOTIS ARVENSIS, Lam., is a denizen probably, being common on 

 dry cultivated fields and waste places, and on roadsides. A 

 large-flowered form grows in two stations ; one being near a 

 ruined castle, the other near an old cattle shelter. This is the 

 common form on cliffs in Eigg. 



MYOSOTIS VERSICOLOR, Retchb., is a denizen probably, or a colonist. 

 It is common in waste places, and on the sides of dry cultivated 

 fields, and on roadsides. 



(SCROPHULARIA NODOSA, Z., is a native probably. It is generally 

 distributed, but is not common. Although most frequently 

 found close to houses, on waste places and roadsides, and by 

 sides of streams, it also occurs among rocks remote from houses.)
