both, flowering and cryptogamic, have been dis¬ 
covered. Rosa alpina is a native of the Pyrenees, 
in Middle Europe. 
12. Rudheckia laciniata is a North American species 
and is naturalised in one or two places on the margin 
of the river. It grows in considerable quantity near 
Orchard Neuk, on the right bank of the river below 
the Friarton. Being a large showy plant it is likely 
a garden escape, and has probably been brought 
hither by the river floods at some remote period. 
13. Sanguisorba Canadensis grows near the river 
side about a mile below Perth and has every appear¬ 
ance of having been there for many years. It, as its 
trivial name imports, is a native of Canada. 
14. Senecio Doria gTOws on the left bank of the 
Tay, near the railway bridge. It was discovered 
this summer by one of our members, ISIr Lamb, of 
King Street, and was believed at the time to be 
Senecio saracenicus. We have since had an oppor¬ 
tunity of submitting it to an eminent botanical 
authority, who pronounces it Senecio Doria and not 
saracenicus as was supposed. It is a native of the 
middle and south of Europe. 
We have thus enumerated the exotics naturalised 
in this neighbourhood. Perhaps further research 
may be rewarded by the discovery of several others 
which have taken up their abode in our free country. 
A short conversation succeeded each of the papers. 
A unanimous vote of thanks was awarded to Messrs 
Stewart and Sim for their communications.
