Arnoseris pusilla , Goertn.—This has not been found for many 
years, and must have been a casual. 
Lapsana communis , L.—One of these doubtful plants which occur 
only in or near cultivated ground. Though not used now, it was 
formerly eaten, but that is no argument against its being indigenous. 
Crepis virens , L.—A weed of cultivation, and hence doubtfully 
indigenous. 
Lactuca mrosa , L., has, I think, been regarded by some local 
botanists as a possibe introduction on Kinnoull Hill and other places 
where it grows in the neighbourhood of Perth. It attains its 
northern limit here, but there are no grounds whatever, so far as 
I know, for supposing it not to be a native. It has been cultivated, 
but only, I think, long after it was known to occur in Perthshire. 
Lactuca muralis , Fresen.—Perthshire is given, as a Scottish 
locality, in the Student’s Flora without any qualifying remark. The 
only station I know for it is, however, on a wall near Crieff, and this 
cannot be looked upon as a probable locality for a native. 
Sojichus arvensis , L., S. oleraceus , L., and S. asper , Hoffm.— 
Chiefly occurring as weeds of cultivation, but not entirely. 
Tragopogon pratensis , L.—From the places in which this edible- 
rooted plant sometimes occurs it is not altogether above suspicion. 
Yet in other stations it seems wild enough, and as it is undoubtedly 
native both north and south of Perthshire, it is probably so here. 
Campanula glomerata, L. — The distribution of this plant, being 
almost, if not entirely, confined to the sea-coast in this part of Scot¬ 
land (although elsewhere it is not so restricted), makes it imperative 
that the question of its nativity on the banks of the Tay above Stanley 
should be considered. It has been known in that station for a very 
long period, and, although stragglers occasionally come down the 
river, it is practically confined to a comparatively short area on both 
banks. If it had been an introduction it is reasonable to suppose 
that it would have long ago spread all down the river. As it has not 
done so, and with due consideration of all the circumstances of its 
occurrence, I think that it must be included amongst the natives. 
Anagallis arvensis , L.— A weed of cultivation. 
Fraxi?ius excelsior, L.—Hooker says “generally planted.” It is 
often self-sown from planted trees, but in some parts of Perthshire it 
is undoubtedly native. 
Echium vitlgare , L.—“An alien or colonist in Scotland” (Watson). 
It is certainly, however, independent of man for its continuance, and, 
I think, may be claimed as a native. 
Symphytum officinale , L.—Watson calls this a denizen in North 
Britain. It is a plant that was formerly cultivated, and now occurs, 
with us, chiefly in the form of solitary plants on the banks of the Tay 
and other rivers. In these cases it seems most probably an escape 
only. In a wet wood near the Pond of Drummond the ochreous
