BOTANICAL SOCIETY OF EDINBURGH xx ks 
British Botany, new edition, by Messrs. H. & G. Groves, 
from Kew and Mortlake on the river Thames; by the 
river Tay below Perth; Benniebeg Pond near Crieff; and 
by the river Boyne near Navan. It is probably an intro- 
duction in these places. As an alien it occurs plentifully 
in Leith Docks and other places round Edinburgh. 
“The specimens shown and named by Professor Hackel 
were gathered by myself in 1907 on and along the 
foot of a retaining wall, and at the foot of a hedge 
opposite, along the public road on the centre hill, north of 
Kenmure Castle, and near New Galloway, Kirkcudbright- 
shire, where there is not the slightest suspicion of this 
grass being an alien. Professor Hackel in his note says: 
‘You may perhaps find that stone walls are not a proper 
station for Poa palustris, L., but this species is really to 
be found not so seldom in such localities. Your plant 
agrees with one in my herbarium from walls near Bozen, 
Tyrol. It is true that the ligule is the only character that 
distinguishes P. palustris, L., from P. nemoralis, Li”
