102 FLORA OF ARROCHAR MOUNTAINS. 
GALIUM SAXATILE, L. 
The most abundant plant of the hills, growing luxuriantly and 
flowering profusely at all altitudes, and in every conceivable 
habitat. Spreading over all parts of the moors, wet and dry—in 
the recesses of the woods, and on sphagnum bogs—trailing over 
dry rocks near the seashore, and on the moist humus at the 
summits of the mountains, the ubiquitous heath-bedstraw carpets 
the ground everywhere with its dainty clusters of small white 
flowers and slender trailing stems. Hooker gives 3,700 feet as 
the altitudinal limit of this species in Britain—a height not attained 
by any of these mountains. Certainly on the exposed summit of 
Ben Ime it seems perfectly at home. 
GaLiumM WITHERINGI, Sm. 
Wet places in Glen Loin ; not ascending the hills. 
GaLiuM APARINE, L. 
Roadsides, borders of fields, and hedges ; low ground only. 
ASPERULA opDoRATA, L. 
Frequent in the woods on Loch Lomond side and in Glen 
Loin. Not observed on the hills. 
VALERIANA OFFICINALIS, L. 
Common by the side of streams. Altitudinal range not deter- 
mined. 
VALERIANELLA OLITORIA, Poll. 
On walls facing the sea at the head of Loch Long. 
SCABIOSA SUCCISA, L. 
Common on pastures and moors throughout the district, ascend- 
ing to 2,000 feet on the mountains. 
SoLIDAGO CAMBRICA, Huds. 
Forms of the golden-rod agreeing most nearly with the descrip- 
tion of this species are common on these hills. The differences 
between this and the type of S. Virgaurea, Z., however, are not 
clearly defined. The mountain plant has usually a shorter stem,
