The submei'sed 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, Hucls., and Myriophyllum spicatum, are fairly abundant, although 

 they do not appear to be thriving very well. Potamogeton pectinatus and 

 Ranunculus peltatus ai-e 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 occui-rence 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 stonj^ 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, Juneus effusus, J. glaucus, J. acutiflorus, Phalaris arundinacea, 

 Deschampsia caespitosa. Spiraea Ulmaria, Cnicus palustris, Pedicularis 

 palustris, Comarum palustre, Carex flacca, C. Goodenovii, Angelica sylvestris, 

 Veronica 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
