consisting of stones, sand, and other detrital matter brought down by 
the river. Although this little spot is swept by every considerable 
flood, yet it has a great variety of plants, some of which are 
alpines, brought down by the river. Fig. 9 illustrates this 
apparently barren spot, which, however, contains sixty-two species 
of flowering plants, as follows : — Ranunculus Flammula, R. acris, R. 
repens, Trollius europseus, Yiola palustris, Cardamine palustris, 
Sagina procumbens, Cerastium vulgaris, Geranium molle, G. 
Robertianum, Spiraea Ulmaria, Alchemilla vulgaris, A. alpina, Rosa 
canina, Potentilla Tormentilla, P. anserina, Galium saxatile, G. 
palustre, G. horeale, Trifolium procumbens, Veronica scutellata, 
Brunella vulgaris, Myosotis palustris, Peplis Portula, Epilobium 
montanum, E. alpinum, E. tetragonum, Euphrasia officinalis, Crepis 
paludosa, Beilis perennis, Centaurea nigra, Senecio vulgaris,. 
Leontedon autumnalis, Tussilago Farfara, Plantago media, P. 
lanceolata, Rumex Acetosella, R. Acetosa, R. obtusifolius, Polygonum 
viviparum, Betula glutinosa (young), Alnus glutinosa (young), 
Salix. two sp. (young), Triglochin palustre, Juncus squarrosus, J. 
articulatus, J. bufonius, J. trifidus, J. effusus, Luzula campestris, 
L. sylvatica, L. multiflora, Carex rigida, C. aquatilis, C. rostrata, 
Eestuca ovina, Lolium perenne, Deschampsia flexuosa, Alopecurus 
geniculatus, Anthoxanthum odoratum, Glyceria aquatica (terrestrial 
form). 
The plants dominating this hank are of the tenacious rooting 
type, as Rumex, Juncus, etc. In the shallow water hereabout are 
quantities of Batrachospermum moniliforme attached to the stones. 
The Caledonian Canal entrance into Loch Ness has a luxuriant 
aquatic flora upon its embankments, but almost limited to Lobelia 
Dortmanna, Juncus fluitans, Callitriche hamulata, and Myrio- 
phyllum alterniflorum. From here, past the river Oich embouchure 
to the point beyond the railway pier, the flora is extremely scanty 
(p. 987). There is practically no shore; the rocks have occasional 
patches of Nardia emarginata or Scapania undulata, and are 
sometimes green with Zygnema. Rounding this point we enter 
Inchnacardoch Bay. The water over a considerable area here is 
under 20 feet deep, with a sandy or muddy bottom, bearing a 
luxuriant vegetation. The only island of Loch Ness is at the 
entrance to this bay — Cherry Island (fig. 10). The aquatic flora.
