FLORA OF ARROCHAR MOUNTAINS. gI 
NASTURTIUM OFFICINALE, R.Br. 
Common in ditches and watery places. Ascends to 2,900 feet 
on Ben Ime. 
CARDAMINE PRATENSIS, L. 
Frequent throughout the district, and ascending the hills to 
some distance. At a moderate elevation it is a not uncommon 
plant of the rock ledges. Noted at 2,000 feet on Crois. 
CARDAMINE HIRSUTA, L. 
Very abundant on walls and banks around Arrochar and 
Tarbet. Ascends to 1,000 feet on Ben Vorlich. 
COCHLEARIA OFFICINALIS, L. 
On the shore, near the mouth of the Glen Loin burn. Not 
abundant. 
CocHLEARIA ALPINA, Wats. 
Alpine, and confined to high altitudes, not descending below 
2,000 feet. This is a sub-species (perhaps merely an alpine form) 
of C. officinalis, L., differing from the sea-shore plant principally 
in the shape of the pods, which are oblong and narrowed at both 
ends, instead of being almost globose as in that plant. C. alpina 
is fairly abundant on the Arrochar peaks, though not growing on 
the actual summit in any instance. The highest altitude noted 
is 3,000 feet on Ben Ime. 
SISYMBRIUM OFFICINALE, Scop. 
On waste ground near the shore, at Arrochar. 
CAPSELLA BURSA-PASTORIS, Mcench. 
Roadsides and edges of fields ; not ascending. 
VIOLA PALUSTRIS, L. 
Very common all over the district, and at all altitudes, attaining 
over 3,300 feet on the summit of Ben Ime. This violet is a 
characteristic plant of moist alpine pastures, especially at a high 
elevation. It occurs also in wet meadows associated with Juncus 
acutifiorus, and beds of Eriophorum. 
VIOLA SYLVATICA, Fries. 
a Common in woods, along the banks of streams, and on rock- 
_ ledges. Ascends to 2,700 feet on Ben Arthur.
