E have ourselves in the Flora Scotica fallen into the
error of considering the Avena alpina of Sir James Smith,
which is not uncommon in the Scottish Highlands, as the
A. planiculmis of Schrader. The true plant of Schrader
has only hitherto been found, and that lately, in one spot in
Britain, namely, at Glen Sannox, on the ascent of Goat-
fell, from Loch Rannoch, in the Isle of Arran, Scotland,
by Mr. Stuart Murray. Cultivated in the garden, it preserves
all its characters, and in every respect agrees with
our wild German ones, and with others from the Continent,
cultivated in the Botanical Gardens of Edinburgh and
Glasgow.
