and on this occasion the atmospheric conditions produced some 
curious effects. We did not see very much of interest in the bota¬ 
nical way, though one or two somewhat local plants were observed. 
The geology seems to be worth attention, especially the conglomerate 
hills and hillocks near Comrie and the great quantity of erratics on 
the moor at the highest part of the road. The distance from Green- 
loaning to Comrie is about 13 miles. 
On 13th August Mr. Barclay and I made another traverse, going 
from New Scone, by Rait and Kinnaird, to Inchture. The day was 
one of those very hot ones which have made the weather of this 
August so remarkable. Nothing particularly noteworthy amongst 
plants was observed till we got to Rait. Here the Sweet Briar (Rosa 
rabiginosa) began to occur not uncommonly, but in nothing like the 
vast profusion with which it grows between Fingask and Kinnaird, 
the road between these places being lined on each side to the 
exclusion of almost every other rose. At Fingask Cynoglossum 
montanum was seen in the station where it has been known for many 
years, and in a quarry Mentha sylvestris and M. viridis were found. 
Mentha sylvestris was afterwards seen in very great abundance in 
several places near Kinnaird. On hedge banks near Fingask Malva 
sylvestris assumes more of the character of a wild plant than it usually 
does, but is doubtless only an escape. In a beanfield near Ballin- 
dean Anthemis Cotnla was gathered. This is a rare plant in 
Perthshire, and sporadic only. 
As Professor Trail of Aberdeen wished to see the Roman Camps 
at Ardoch, Mr. Barclay and I accompanied him thither on 19th 
August. After “ doing ” the camps and finding Vaccinium oxycoccos 
in a marshy place in one of them, we took the road to Blackford by 
Orchill. Within sight of the road are various small marshes which 
at an earlier period of the year would probably repay examination. 
In one of these spots, close to Orchill, Veronica Anagallis was seen, 
and in a ditch a small bed of Glyceria plicata. Another marsh pro¬ 
duced Carex limosa , and the pastures near it Habenaria viridis. 
When within about a mile from Blackford we struck across the fields 
to the river Allan, finding in another marsh Orchis incarnata , or 
what appears to be that species from the hooded leaf-tips. In a field 
near the river some curious forms of Polygonum Persicaria attracted 
our attention. 
Veronica Anagallis was again observed, and seems to be common 
on the banks of the Allan. I forgot to mention that Rumex con- 
spersus was gathered near the site of the “Great Camp” at Ardoch. 
On 23rd September—a day whose low temperature was in marked 
contrast to what we had experienced in Glenartney three weeks pre¬ 
viously—Mr. Barclay and I went over some old ground, and were 
not unrewarded. Our route was the left bank of the Tay from Barn¬ 
hill to Darry Island, thence inland past Ivinfauns Manse to the 
Balthayock Road, and thence by Pepperknowes Farm to Glencarse 
Station. The bank of the river did not yield anything new, but 
exhibited a number of plants in flower for the second time. This
