be really native. At Ardblair, near Blairgowrie, it grows in thoroughly 
wild ground, the whole aspect of which tends to support the 
opinion that the species cannot have been introduced. Another 
locality is near Rait, on the Braes of the Carse. Here it grow r s on a 
steep, dry, warm bank, which, though cultivated in places, yet pro¬ 
duces several other local and rare plants, and the association of 
R. lutea with these seems to be an argument in favour of the plant 
being native. 
R. Luteola , L.—From having been used as a dye-plant, this 
species might be looked on with some suspicion. It seems, how r ever, 
to be considered as wild, and as such I am content to leave it. 
Viola tricolor, L.—The books say that this is a plant of culti¬ 
vated ground. It is, however, by no means confined to ground of 
that nature, and is a true native. 
V. arvensis , Murray.—A w r eed of cultivation. 
Lychnis alba, Mill.—Although no doubt has been cast upon this 
as a native, it is one of these hedge-bank and field plants w r hich ow r e 
much to man as regards places suitable for their growth. 
Spergula arvensis , L.—Mostly, and perhaps entirely, a w r eed of 
cultivation. 
Malva sylvestris , L.—Watson doubts this being native in Scot¬ 
land. With us it is never more than an outcast. 
Malva moschata, L.—This is admitted to be native from Fife 
and Dumbarton southwards. In Perthshire it is perhaps doubtfully 
native, yet on the whole I am inclined to think that it may be wild 
in some places. 
Gera?iium perenne, Huds.—Certainly an alien with us. 
Rhammns Frangula , L.—Although w T e as yet know of one plant 
only of this (near Loch of Low r s), there seems to be no reason why 
it should not be native. The situation is a wfild one, and the 
species is not likely to have been introduced into it purposely or 
accidentally. 
Melilotus altissima, Thuill., is called a denizen by Watson. Here 
it is not more than a casual. 
Lathyrus niger , Wimm.—Watson is doubtful about this being 
native, but for wffiat reason I know T not. Any one who has seen it 
in the Pass of Killiecrankie can entertain no doubt as to its being 
really wild. 
Primus Avium, L.—It is common enough as an unplanted tree, 
but w r hether it is more than a wanderer from cultivation, or whether 
in some cases, at least, it is native, is a problem difficult of solution. 
Spircea Filipendula, L.—Since this occurs at one spot only—on 
the banks of the Tay above Kinclaven—some botanists may have 
some suspicions about it. A double-flow r ered form is sometimes met 
with in gardens, but I have not seen the single-flow r ered plant—which 
is the Kinclaven form—cultivated. The plant is locally abundant 
and not near any garden; and since it occurs as a wild species as far
