452 BOTANICAL TOUR IN THE 
the Coilantogle road. The botanical aspect of the vegetation on 
the wayside, tempted us into a wood about half a mile from 
Callander, and about midway between the bridge of Callander 
and the bridge near Coilantogle. In this wood, among other 
things of some interest, were collected Trollius ewropeus, both in 
flower and in fruit; also Trientalis europeus, now very nearly out 
of flower, and Vaccinium Vitis-Idea. Vinca minor was collected 
at Callander, but the reporter is not quite sure that it was ob- 
served in this wood. A very fine Rubus was observed here and 
in many other parts of Perthshire. The blossoms were pure 
white, and the erect habit of the plant, with its large flowers, 
rendered it there a very ornamental object. The common Orchids 
abounded here, as they did all along the roadsides from Callan- 
der to Loch Katrine. One of the most remarkable,—not for its 
rarity, for it occurred plentifully, but for its singularity, in having 
but a single flower at the extremity of the stem,—was a variety 
of Orchis maculata, which variety might be called var. uniflora. 
Plenty of the more common forms grew in the same spots, some 
with larger, some with smaller spikes. 
After spending half an hour in botanizing among the trees, we 
rejomed the road and travelled onwards, crossig the western 
branch of the Teith by the bridge near Coilantogle, and, a little 
further on, met the coach-road to Loch Katrine by Kilmahog, 
the northern and most picturesque of the two roads leading from 
Callander to this celebrated locality. The northern road was 
not new to us, and the one we chose was not only so, but it 
shortened our journey two miles. The road skirted along the 
eastern shore of Loch Vennachar and we were induced to look 
into the lake for aquatics. None however were visible except a 
few plants of Littorella lacustris. On the roadside, where the 
road impinges on the wooded hill, a solitary plant of Hypericum 
Androsemum was observed, the only example of this fine species 
noticed by us in all our walks onward and aside, forwards and 
backwards, and these amounted, on a rough calculation, to up- 
wards of 250 miles. 
The absence of wayside (viatical) plants, which abound in the 
south of England, was one of the singular features of all our walks 
in Scotland. A botanist could scarcely walk twenty miles in 
England without seeing some examples of Hypericum perforatum, 
the most common of the genus in the midland and southern
