II2 FLORA OF ARROCHAR MOUNTAINS. 
POLYGONUM LAPATHIFOLIUM, L. 
Waste ground near the shore at Arrochar, and in Glen Loin. 
POLYGONUM VIVIPARUM, L. 
Alpine.—This species is not at all common on these mountains, 
but occurs on Crois and on Ben Ime, and may probably be found 
on the other hills. The altitude has not been noted. 
OXyYRIA RENIFORMIS, Hook. 
Alpine.—Very abundant along the watercourses from about 
1,500 feet upwards. Ascends to over 2,800 feet on Ben Arthur. 
RUMEX OBTUSIFOLIUS, L. 
Waste places ; low ground only. 
RUMEX cRISPUS, L. 
Waste ground, especially near the seashore ; low ground only. 
Rumex Acetosa, L. 
Common everywhere in pastures and alpine moors, ascending 
to high altitudes. It occurs on the extreme summits of all the 
hills except Ben Narnain—hence attaining over 3,300 feet on Ben 
Ime. 
RUMEX ACETOSELLA, L. 
Dry banks and wall-tops ; low ground only. 
MERCURIALIS PERENNIS, L. 
In the woods and shady places; ascending to 1,800 feet on 
Ben Vane. 
Urtica pioica, L. 
The distribution of the nettle is an interesting problem. It is 
to be met with on the hills at places where buildings have at one 
time existed, but does not spread beyond these. Its limits seem 
to be determined by the operations of man. 
Myrica GALE, L. 
Abundant all along the bases of the mountains, but not ascend- 
ing. In one or two localities this shrub attains great luxuriance, 
as is the case, in particular, near the base of Ben Vorlich above
