14 PHANEROGAMS AND FERNS OF SOUTH ARDGOIL. 
where it flowers as low as 100 feet. It does not occur on the 
summit of any of the hills, but ascends nearly to it. It appears 
to be absent south of the Pass of the Saddle, and quite com- 
mon to the north of it. The presence of Alchemilla alpina by 
the side of a stream is a sure index (locally) that the head- 
waters are above 1750 feet. 
Broad-leaved Willow-herb (Epilobium montanum, Linn,)— 
Common by the shore and the sides of the roads and burns up 
to 500 feet. 
Square-stalked Willow-herb (Zpilobiwm tetragonum, Linn.) — 
See Roadsides (p. 3). 
Narrow-leaved Marsh Willow-herb (Zpilobium palustre, 
Linn.)—Occasional in wet places by the roadside and on the 
hills, mainly among rushes up to 1100 feet. (Epilobium 
alpinum, Linn.)—On Cnoe Coinnich at 1800 feet. 
Enchanter’s Nightshade (Circa lutetiana, Linn.) —See Wood- 
lands (p. 4). 
Rose-root (Sedum rhodiola, De.)\—Very common on rock 
faces from 1500 feet upwards ; occurs in Eas Garbh as low as 
450 feet. It has the same range as Alchemilla alpina, being 
plentiful to the north of the Pass of the Saddle, but absent to 
the south. 
English Stone-crop (Sedum Anglicum, Huds.)—Frequent on 
rocks by the shore, and at low levels. 
Purple Mountain-saxifrage (Saxifraga oppositifolia, Linn.)— 
Frequent over the higher rocks from about 1400 feet up to 
1800 feet, and occasionally in the allts; in Eas Garbh at 
450 feet ; not to the south of the Pass of the Saddle. 
Yellow Mountain-saxifrage (Saztfraga aizoides, Linn.)— 
From sea-level up to 1800 feet; most common above 1000 
feet, but occurring in patches in the beds of the streams and 
in rocky hollows at all levels, including the shore, being the 
most common and widely distributed saxifrage. 
Mossy Saxifrage (Saxifraga hypnoides, Linn.)—Only at high 
levels, 1500 to 2000 feet ; the least common of the saxifrages, 
and only north of the Saddle. 
Starry Saxifrage (Saxifraga stellaris, Linn.)\—From 1000 to 
1900 feet; most common above 1500 feet, but descending the 
allts to 350 feet in Allt Inverlounin ; not south of the Saddle. 
Alpine Clustered-saxifrage (Saxifraga nivalis, Linn.)—At 
1800 feet on a ledge of Cnoc Coinnich. ’
