absolutely certain on this point. I am inclined to think that the 
form found is the var. guestphalicum Bugh., but, as I have not seen 
examples of that variety, I cannot be sure. On a wet bank, at about 
300 feet elevation above sea level, Saxifraga stellaris was seen. 
Although another of the mountain saxifrages (S. aizoides) is 
frequently brought down by the streams from its home on the hills, 
I never before saw S. stellaris at so low an altitude. Our other finds 
included several forms of Thalictrum minus , as well as Poly gal a 
vulgaris , Symphytum officinale , and a naturalised bush of Cornus 
sanguinea —the latter being noteworthy as, though not unfrequently 
planted, we had not before seen it in a semi-wild condition. 
A little time was devoted to an examination of Ballinluig Island, 
near Logierait. The island is mostly covered with fir trees, amongst 
which Silene maritima and Alchemilla alpina grow in some abundance 
—rather a curious-looking locality for these species, which, though 
common on the shingles, usually disappear when these become over¬ 
grown with trees and bushes. 
The next excursion took place on July 5th. Starting from Killie- 
crankie Station, we crossed the river and explored some marshy 
ground near the head of the Pass. Here Tofieldia palustris is not 
uncommon, though the altitude is only about 600 feet, the lowest at 
which we have seen it. Amongst other plants here were Saxifraga 
aizoides , Eriophorum lat folium, the orchid we have been accustomed 
to call Orchis incarnata , and Gymnadenia Co 7 iopsea with white flowers 
—a state we had not noticed previously.* 
Leaving the marsh, we turned our attention to the rocky slope of 
the hill which forms the western boundary of the Pass of Killiecrankie. 
These rocks we knew, from past experience, to be rather rich, pro¬ 
ducing, amongst other things, Lychnis Viscaria in some abundance.

not included. Additions to the list will be welcome.
