FLORA OF SCOTTISH LAKES

that there is no shore. The water is quite clear and scarcely peaty. 
On the east side there are thin beds of Carex rostrata. On the west 
side there are associations of Scirpiis lacustris and Carex rostrata. On 
grassy bogs, which occur here and there at the margin, the usual bog 
plants occur. Nothing of particular interest was noticed at this loch. 
Loch Brack is a mile north-east of Barscobe Loch, and is similar 
to it in general features, but smaller. Between the grass moor and 
the water a narrow zone of Juncus acutiflorus intervenes more or 
less all round the loch. An average number of common plants occur, 
but nothing of special interest was observed here. 
Loch Howie is two miles north-east of Barscobe Loch, and is 
larger than it, being three-quarters of a mile long, but very narrow. 
In general features it again resembles Barscobe Loch. There are 
associations of Phragmites communis and Scirpus lacustris, whilst 
Carex filiformis occupies situations usually taken up by C. rostrata. 
A number of common plants occur here, but nothing of special 
interest was noticed. 
Loch Skae is a small oval loch about a quarter of a mile long, 
situated half a mile east of Loch Howie. The general flora is similar 
to that of the three lochs just mentioned, but the physical features 
are different. The surrounding moors have more heather and peat ; 
the scenery, particularly on the east, is rocky and wild ; the water 
is a little more peaty, and the east shore is rocky or stony. Isoetes 
lacustris, Utricularia intermedia, and Potamogeton polygonifolius 
are more abundant here than at the other three lochs. The rocks 
on the east shore are overgrown with mosses, chiefly Hypnum 
cupressiforme and Rhacomitrium aciculare. About the margin there 
are associations of Phragmites communis, Carex rostrata, and C. 
filiformis. 
Lochinvar is four miles north-east of Dairy. It is about half a 
mile long and one-third of a mile wide, and is situated at an elevation of 
737 feet above sea-level in a depression of a hilly, grass and heather 
moor. The scenery around is bare, desolate, and, with the exception 
of a few conifers about the gamekeeper's house, treeless. The water 
is very clear, and but slightly peaty. Generally the moorland 
vegetation approaches almost to the water's edge, so that there is 
practically no shore. The bottom is rocky nearly everywhere, and, 
with the exception of a few species which are abundant in some 
parts, the flora is extremely poor. There are no formations of 
marsh plants about the shores ; such of these plants as do occur are 
either as scattered specimens or in a few very small groups. The 
submerged plants are more interesting, although these too are very 
poor in species ; yet four species of Potamogeton are abundant in 
some places.
