Aster salicifolius, Scholl. 
Province- 11-15. By the river Tay, below Perth; Syme! 
Alien. Comp. 641*, Aster salignus in part. Perhaps more than 
one species pass under the name salignus. The examples sent 
to me from Perth, by Dr. Boswell Syme, well correspond with a 
specimen from [name not legible] labelled by Hornung as 
“A. salicifolius Scholl.” I am not certain that the Cumberland 
plant belongs to the same species; and have not seen that of 
Cambridge. The Perth specimens ill accord with one from 
Strasbourg, sent as salignus. 11, N. H. of Eastern Borders. 
Aster Novi-Belgii, Linn. A. brumalis?
