The submersed aquatic plants are uninteresting and comparatively scarce. 
Littorella lacustris is abundant, and in many places forms a sward on the 
shore when the water has fallen. Potamogeton crispus, as well as the f. 
serratus, Huds., and Myriophyllum spicatum, are fairly abundant, although 
they do not appear to be thriving very well. Potamogeton pectinatus and 
Ranunculus peltatus are scarce. Enteromorpha intestinalis is scarce, whilst 
Cladophorse abound. In the paucity of submerged plants this loch agrees 
with some others in which “ water-bloom ” occurs in early summer, and, ex- 
cepting for the occurrence of this phenomenon, the loch would probably 
support a rich aquatic flora. 
This loch was one of the first recorded stations for Potamogeton Zizii in 
Britain, the spot, indeed, where Mr Boswell (Syme) collected the specimens 
which he distributed under the name of “ P. lucens with floating leaves,” 
subsequently referred to P. Zizii. This plant, however, now appears to be 
extinct in the loch. 
Loch Camilla is a small oval sheet of water about 4 miles east of 
Cowdenbeath. The water, which is not peaty, is rather turbid, and is 
surrounded by meadow -land which approaches almost to the margin of the 
water. The narrow shore on the east, south, and north is stony and bears 
but few plants, but at the west end there is a considerable development of 
marsh vegetation. A large association of Equisetum limosum, mixed here 
and there with patches of Hippuris vulgaris, stands out in the water. 
Nearer the land there is a large association of Carex rostrata, behind which 
there is a wide stretch of bog gradually merging into meadow, and this bog 
is covered with the following plants : — Menyanthes trifoliata, Heleocharis 
palustris, Radicula officinalis, Caltha palustris, Cardamine pratensis, Mentha 
sativa, Galium palustre, Myosotis palustris, Ranunculus Flammula, Alisma 
Plantago, Juncus effusus, J. glaucus, J. acutiflorus, Phalaris arundinacea, 
Deschampsia csespitosa, Spiraea Ulmaria, Cnicus palustris, Pedicularis 
palustris, Comarum palustre, Carex flacca, C. Goodenovii, Angelica sylvestris, 
V eronica Beccabunga, Ranunculus hederaceus, and a curious semi-terrestrial 
form of R. peltatus, with purple blotches on the peltate leaves, which 
suggests a crossing with R. hederaceus. A number of Bryophytes are also
