This is no doubt a plant which has been intro- 
duced for medicinal purposes. It is one of a small 
croup often found in kale-yards.

Some of these are white beneath the leaves and 
densely tomotose, which seems to be Buchanan 
Whyte’s variety argenteus. In Hooker's “ Flora,” 3rd 
edition (Students’), var. setosus (Bess.) 1s given as 
growing in Orkney. Dr Fortescue writes :—<In 
‘English Botany’ the following occurs :— Var. setosws 
not native, but found about Culross, not far from 
Dunfermline; it has also been found about Battersea, 
Hartlepool, and at Kirkwall, Orkney. I have speci- 
mens of this plant from England, and could not have 
overlooked it had I met with it in Orkney. I looked 
at every patch of arvensis which I saw in Orkney 
with the hope of meeting with it, but never did so. I 
think my uncle (Dr Boswell) said it had been found 
between Kirkwall and Finstown. It may have been 
introduced and afterwards died out.”
