north as Caithness, I think we must admit it as a native of Perth¬ 
shire. 
Potentilla anserina , L.—Although this is a plant of roadsides and 
fields, and hence in a great measure dependent on man, it seems 
nevertheless to be really native, and has not been doubted to be such. 
AlchemiUa arvensis , Lamk.—Common as a weed of cultivation, 
but clearly a native. 
Rosa rubiginosa , L.—“ Probably not indigenous in Scotland ” 
(Student's Flora), yet it is common in many wild places, and looks 
as much a native as our other undoubtedly wild roses. 
Fyrus acerba , D.C.—Undoubtedly wild in many places. 
P. Aria , Sm.—Some bushes (mostly inaccessible) grow on the 
rocky hill to the west of Killiecrankie. I have not been able to get 
sufficient specimens by which to determine the variety or sub-species. 
I cannot positively say that the White Beam is native in this locality. 
The rocks are rather rich botanically, and are not very close to any 
garden ground. Moreover, no planted specimens of the tree were 
observed in the district. Although P. Aria is not uncommon in 
shrubberies, &c., in various parts of Perthshire, self-sown specimens 
are of very rare occurrence so far as my experience goes. On the 
whole I am inclined to consider that it is wild on the rocks in 
question. 
Cratcegus Oxyacantha , L.—Though probably often only an escape, 
by the agency of birds, from cultivation, it does occur as a native, 
since I have seen it in spots in which it could scarcely have been so 
introduced. 
Ribes rubrum , L.—If the pubescence or glabrosity of the leaves 
is a sure mark of distinction between the wild and cultivated forms 
of the Red Currant, then the plant which is common on the banks 
of the Tay, &c., must be considered native. I am, however, not 
quite satisfied as to whether all or any of our specimens are really 
wild. 
Sedum Telepliium , L.—Usually a hedgebank plant, and not un¬ 
common about Perth. I think that it is probably not native. 
Lythrum Salicaria , L.—We have usually taken it for granted 
that the plants of this, which occur on the banks of the Tay below 
Perth, are all escapes, whilst we admit it as a native in several other 
parts of the county. That it does come down the Tay was demon¬ 
strated by a plant which stranded on a bank at the Woody Island. 
Whether all the Tay and Earn specimens are really escapes is perhaps 
a little doubtful, but I am inclined to think that they probably are, 
since, as a rule, they are mostly solitary. 
Epilobium angustifolium , L.—Sometimes occurring as an escape, 
but usually wild. 
Umbelliferoe. —In this order there are several species which seem 
to be undoubtedly old introductions, and some others which, from 
their restriction to roadsides, or to cultivated ground or its neighbour-
