DOUBTFULLY NATIVE WESTERNESS PLANTS 185 



ARTEMISIA VULGARIS, Z., is partly a denizen, but is not common, 

 on waste-heaps, sides of cultivated fields, and neighbouring 

 shores. 



SENECIO VULGARIS, Z., is common in gardens and outskirts and 

 waste places, more rarely on roadsides and shores near houses. 



CREPIS VIRENS, Z., is partly a denizen. It is locally common in 

 cultivated fields and beside adjoining roads. On sandy shores 

 near cultivation it grows as a low diffuse form, due (always ?) to 

 the main stem being eaten by ground vermin. 



SONCHUS ARVENSIS, Z., is rare in cornfields. It is abundant in 

 north of Mull. 



LYCOPSIS ARVENSIS, Z., is not common, but occurs in widely separated 

 parts of the district. It is limited to one kind of situation, 

 namely the sandy shore, sides of cultivated fields, and the 

 adjoining sandy shores, as is also the case in Eigg. A list of 

 the kind of situations it inhabits on the west coast would be 

 interesting, as perhaps it may be a native on the sands. 



GALEOPSIS VERSICOLOR, Curt., is rare, in cultivated fields and waste- 

 heaps. 



VERONICA HEDER^EFOLIA, Z., V. AGRESTIS, Z., and V. TOURNEFORTII, 

 C. Gwe/., are rare weeds, limited, as far as I have seen, to 

 gardens and their outskirts. 



LAMIUM AMPLEXICAULE, Z., is rare in gardens and outskirts. 



LAMIUM INTERMEDIUM, Zr., is not common, in cultivated fields, and 

 casually on neighbouring shores. 



LAMIUM PURPUREUM, Z., is not common, in gardens, cultivated 

 fields, and casually on neighbouring shores. 



CHENG-PODIUM ALBUM, Z., is partly a denizen, but rare in cultivated 

 fields and on shores adjoining or near old cultivated fields. 



ATRIPLEX PATULA, Z., var. ANGUSTIFOLIA (Sw.), is not common, in 

 cultivated fields. 



POLYGONUM CONVOLVULUS, Z., is partly a denizen, in cultivated fields 

 and on neighbouring sandy shores. When the fields become 

 permanent grass this plant only keeps its hold on the shore. 



POLYGONUM LAPATHIFOLIUM, Z., is rather common in cultivated fields. 



BROMUS SECALINUS, Z., and B. COMMUTATUS, Schrad., are perhaps 

 rare casuals among sown grass. 



ALIENS. 



PRUNUS AVIUM, Z. Planted by roadsides and near houses. 



PYRUS MALUS, Z., is met with only as old trees near deserted crofts 

 and gardens.
