SENECIO ERRATICUS. Btrtol 
Reported from the Channel Islands and Shropshire, but by 
mistaking S. aquaticus for this species 
ASTER. 
Various species of Aster from North America occasionally occur 
as the outcasts of gardens where they are cultivated, under the 
name of Michaelmas daisy. Anions; these I have seen A. brumalis 
(Nees), A. Novi-belgii (Linn.), and A. leucanthemus (Desf.). 
SOLIDAGO LANCEOLATA. Linn. 
Dr. "Walker Arnott states that this North American species is 
sometimes found "naturalized; " but I have never seen it. 
TUSSILAGO ALPINA. Linn. 
Said by Mr. G. Don to have been found in Forfarshire ; but it 
has been found by no one else ; it is the Homogyne alpina of 
Cassini and most of the continental botanists. 
PICRIS STRICTA. Jord. 
This plant (which appears to be a sub-species of P. hieracioides) 
was found in Buntingford, Ilerts, by the Rev. W. W. Newbould ; 
but probably it has been introduced with seed from the Continent. 
PRENANTHES PURPUREA. Linn. 
Partially naturalized near the Castle, Isle of Skye. I have 
seen it about 1839 on the debris of Salisbury Craigs, Edinburgh, 
but it was not persistent there. 
CREPIS PULCHRA. Linn. 
Eng. Bot. No. 2325. 
Mr. G. Don said that he found this plant among the debris of 
the rocks of the hills of Turin and Pitsandy, in Forfarshire. Dr. 
Walker Arnott remarks in the " British Flora," " The very few 
specimens from Don, which we have seen, are more luxuriant 
than Smith's acknowledged cultivated one, from which the figure 
in 'English Botany ' was made."
