Matriearia discoidea, DC., in North Aberdeenshire. About
twelve years ago I found this plant growing on the seashore beside
the harbour of Rosehearty, on the Moray Firth coast of Aberdeenshire.
Though rather common near the harbour, I did not observe
it elsewhere ; and, regarding it as a "casual," I omitted to record it.
During August of this year I have met with it again. At Boddam,
a little
way south of Peterhead, it occurs on flat low ground on to
which boats are drawn up, much like the place where I first found
it,
but it has not yet spread far from this centre. Near Rosehearty
and Pittulie it is now extremely abundant ;
and it has spread along
the roads inland to the old castles of Pittulie and Pitsligo, and at
least nearly four miles westward, as far as Aberdour. It is especially
plentiful near farm-buildings, sometimes quite covering the ground,
almost to the exclusion of other vegetation. A native of eastern
Asia and western North America,
it has for a number of years been
known as naturalised on the eastern coasts of the North Sea ;
and
it has probably been brought by fishing craft to the Aberdeenshire
ports. It is now most thoroughly naturalised on the north coast of
Aberdeenshire. I am not aware of any previous record for Scotland.
I have seen it on waste ground and rubbish along the Thames at
Kew near London; and it is recorded ("Journ. Bot," 1900, pp.
354-355) as abundant around Falmouth Docks. JAMES W. H.
