PHANEROGAMS AND FERNS 
OF SOUTH, ARDGOIL.. 
By Tuos. NisBet, M.A. 
(Read 8th November, roro.) 
THE purpose of this paper is to place before the Society the 
botanical results of some recent observations on the distribu- 
tion of the phanerogams and ferns of Ardgoil. The district to 
the north of Glencoe has been the subject of a valuable paper 
by Mr John R. Lee [Vol. III., p. 80—“The Flora of the 
Arrochar Mountains”], which includes the northern portion 
of Ardgoil. The following description deals with the penin- 
sular part of South Ardgoil between Loch Goil and Loch 
Long, and defers for further work a description of the Brack 
and Ben Donich. 
The statements made regarding the occurrence of plants 
are based on an extensive series of lists made mainly during 
numerous excursions in July and August of 1910. The 
frequency of occurrence of each plant is estimated from the 
number of times it occurs in the lists, and not from memory 
or impressions, which are apt to be misleading. The traverses 
made of the ground have included as far as possible repeti- 
tions of all the varieties of habitat at different elevations. 
In this way alone can prevailing features as well as local 
peculiarities be accurately ascertained. 
The area dealt with is bounded on the north by Corrie 
Odhair and Coilessan Glen, on the west by Loch Goil, and on 
the east by Loch Long. It is triangular in shape, the 
northern base being about four miles from east to west, and 
the sides about five miles. The range of hills which bounds 
Loch Long is broken by Coilessan Glen, Allt Guanan, and the 
Pass of the Saddle into prominent blocks called The Brack (2580 
feet), The Cnoc (2497 feet), Ben Reithe (2141 feet), and the 
Saddle (1704 feet). To the south-west of the Saddle, and 
separated from it by a stream and lochan, is a rugged ridge 
which culminates in Clach Bheinn (1433 feet). To the west 
of Ben Reithe the irregular ridge of Carn Glas (1648 feet)
