92 FLORA OF ARROCHAR MOUNTAINS. 
POLYGALA VULGARIS, L. 
Common on the moors, ascending to 2,000 feet on Ben Arthur 
and Ben Narnain. Both the blue and white-flowered varieties are 
common throughout the district. The red-flowered form is 
frequent also, but mostly at a low elevation. 
SILENE ACAULIS, L. 
Alpine.—Frequent, and generally distributed over the higher 
parts of the mountains, where it forms dense, cushion-like patches 
in open, sunny situations. Its lower limit of altitude appears to 
be about 1,800 feet, at which elevation it was noted on Crois. It 
ascends to 3,000 feet on Ben Ime and Ben Vorlich. 
LYCHNIS DIURNA, Sibth. 
Abundant in the woods in Glen Loin, and common in other 
parts. This plant occurs also, but not abundantly, on the alpine 
ledges, ascending to 2,700 feet on Ben Arthur. 
Lycunis FLos-cucuti, L. 
Wet meadows in Glen Loin, abundant. 
CERASTIUM VULGATUM, L. 
Roadside near Succoth farm. Apparently uncommon in the 
district. 
CERASTIUM VISCOSUM, L. 
Abundant throughout the district. Ascending to 2,900 feet on 
Ben Ime. 
CERASTIUM ALPINUM, L. 
Recorded in the first appendix to the ‘‘ Clydesdale Flora” from 
Ben Vorlich, upon which mountain I found it in 1892, but did 
not take note of the altitude. Mr. M‘Lean and I gathered it last 
year on Ben Ime at 2,800 feet. So far, these appear to be the 
only records for this species on these hills. 
STELLARIA MEDIA, Vill. 
Cultivated fields and roadsides. Low ground only. 
STELLARIA Ho.osTgEa, L. 
In woods and bushy places. Not ascending to high elevations. 
STELLARIA GRAMINEA, L.
