98 FLORA OF ARROCHAR MOUNTAINS. 
Pyrus Matus, L. 
The wild apple is common on Loch Lomond side, probably as 
a relic of former cultivation. A specimen was noted at 400 feet 
on Ben Vorlich. 
CRAT&GUS OXYACANTHA, L. 
The hawthorn is common throughout the lower parts of the 
district, the highest altitude noted being 500 feet on Ben Vorlich. 
SAXIFRAGA OPPOSITIFOLIA, L. 
Alpine.—Occurring on all the six mountains in the district, 
Mr. Brown having gathered it this year for the first time on Ben 
Arthur. It is fairly common on the other peaks from about 2,000 
to 2,500 feet altitude, but ascends to 2,700 feet on Ben Vane, and 
to 3,000 feet on Ben Ime. Below 2,000 feet it becomes rare, but 
descends as low as 1,500 feet on Crois. Mr. Nisbet reports 
having seen the species as low as 400 feet in the bed of the Allt- 
Sugach, evidently washed down by the stream. This, however, is 
exceptional. 
SAXIFRAGA STELLARIS, L. 
Alpine.—The most widely distributed saxifrage in Britain, both 
in altitude and area. This species is usually met with on our hills 
from about 2,0o00 feet upwards. It is characteristic of moist 
invariable inhabitant of cold springs. It does not usually descend 
much below 2,000 feet, but was noted at 1,800 feet on Ben Vorlich. — 
It ascends to the tops of the mountains, and was noted on the 
actual summits of Ben Ime, Ben Vane, and Ben Vorlich. 
SAXIFRAGA AIZOIDES, L. 
This, although a truly mountain species, is frequently seen q 
growing at low altitudes, sometimes even descending almost to — 
sea-level. Its special habitats are wet rocks, springs, the beds of — 
streams, in the spray of waterfalls, etc. It is common on the iam 
Arrochar hills, ascending to 2,800 feet on Ben Ime. 
SAXIFRAGA HYPNOIDES, L. 
Alpine.—This species appears to be restricted to high altitudes — 
in the Arrochar district, although found at lower elevations else- — 
where in the Clyde area. So far the only records for these 4
