204 THE FRESH-WATER LOCHS OF SCOTLAND

Castalia speciosa, Sparganium natans, S. minimum, Caltha palustris, 
Heleocharis palustris, Equisetum limosum, Glyceria fluitans, Carex 
rostrata, C. filiformis, C. aquatilis, C. Goodenovii, C. binervis, Erio- 
phorum vaginatum, E. polystachion, Juncus articulatus, J. supinus, 
Triglochin palustre, Ranunculus Flammula, Sphagnum various sp., 
Blindia acuta, Brachythecium rivulare, Hypnum cuspidatum, H. 
uncinatum, Philonotis fontana, Scapania undulata, Nardia emarginata, 
N. compressa, Batrachospermum moniliforme, Zygnema Vaucherii, etc. 
Loch Meiklie is situated in Glen Urquhart, at an elevation of 
365 feet above sea-level. It differs from the lochs of this area 
hitherto considered. Its shores are beautifully wooded, and mostly 
stony or sandy ; but about the embouchure of the river Enrick at 
the west end there is a considerable swamp. Some of the sheltered 
bays, notably towards the north-east, have also swampy margins. 
Besides moorland, this loch also drains a small area of cultivation ; 
its water is, therefore, less peaty than usual, although it contains a 
considerable amount of matter in suspension. At the marsh at the; 
west end of the loch, the pLmts are arranged in succession somewhat 
as follows, proceeding from the drier ground towards the water : — 
Juncus effusus, J. articulatus, Carex rostrata, Phragmites communis, 
Equisetum limosum in water 2 to 5 feet deep, Castalia speciosa in 
water 4 to 8 feet deep, Nymphaea pumila in water 8 to 10 feet deep ; 
beyond the last- mentioned, at the bottom, Potamogeton pusillus, 
var. tenuissimus, P. lucens, Utricularia vulgaris, and Nitella trans- 
lucens. All these associations are of course mixed with other plants, 
but those mentioned are dominant over a certain area. The Castalia 
speciosa association is extremely well developed here, and presents a 
magnificent spectacle. A considerable number of other plants also 
occur at this loch. 
Ascending the hills north of Glen L^rquhart, there are many 
mountain lochs differing somewhat in character from any hitherto 
seen, although some are of the usual mountain type. Many of the 
lochs on these hills have a great abundance of Castalia speciosa in 
its normal form, the associations of which frequently extend in huge 
crescents, chiefly about the western side of the lochs or in bays. 
There is also in many cases a luxuriant swamp of Scirpus lacustris, 
etc. The general vegetation of the lochs, although restricted in
