binding nature, forms a coarse-grained calcareous sandstone—of 
which considerable “quantities are carted to a lime-kiln, near 
Aranagour, and burned as lime for building and agricultural 
purposes. 
As the surface of the island is broken up by numerous small 
lochs and peat-mosses, and by many small streams, and as there 
are numerous sheltered bays and inlets, it is evident that 
there is a great variety of soil and situation favourable to many 
different plants. So that the more one extends his researches the 
more is he surprised at the comparative richness and variety of 
the flora. 
I will now proceed to enumerate a few of the more interest- - 
ing species. 
Thalietrum minus is plentiful along the sandy shore of the west 
coast. Mymphaea alba grows in a small loch not far from the over- 
seer’s new house, near Aranagour. Papaver (sp.?) I noticed in a 
corn-field near the Free Church. Avrabis hirsuta was found in a 
meadow, not far from the school-house. Geranium sanguineum, in 
most beautiful profusion, was found growing on the banks of a 
stream, not very far from Major Stewart’s house, and I felt fain to 
linger beside this lovely spot. Geranium sanguineum is one of 
our finest wild flowers, and is also one of those that are never so 
beautiful as when growing in the wild freedom of their native 
habitat. Long-leaved Sundew was very plentiful beside a small 
loch about a mile-and-a-half from Aranagour. I did not get it in 
flower, but from the lengthened petioles I have marked it Drosera 
anghca. Veronica anagallis was found completely filling the bed 
of a stream flowing west, not very far from the school-house, and 
I never saw finer plants; they were just beginning to flower, and 
at that time would be fully two feet in height. Ajuga pyramidalis 
I found in a few places, and it seemed to favour rocky situations. 
This plant seems to be very restricted in its distribution as far as 
the British Islands are concerned, being confined to the North of 
Scotland and West of Ireland. The number of counties set down 
for it in the London Catalogue is 9, while some of our commonest 
plants reach as high as 103. 
The next I have to notice is one of the interesting insectiverous 
plants, Utricularia (sp.1), which was frequent in ditches having an 
outlet into the small loch already mentioned as situated behind the 
overseer’s new house. The plants were very attenuated, and
