352 The Scottish Naturalist. 



Growing singly in muddy places, an Isoetes was seen, but on 

 examination proved to be only lacustris, instead of the hoped- 

 for echinospora. 



Elatine hexandra grew in little patches here and there, and 

 amongst Nuphar the pale green leaves of a Sparganium tried 

 in vain to reach the surface. Failing by a long way to do so, 

 the plants refused to flower, but appeared from the character 

 of the leaves to belong to S. minimum. A few plants of Utri- 

 cularia were fished up, but to what species they belong puzzles 

 me to say. It is certainly not intermedia, and besides being 

 too stout for minor, has the segments of the leaves furnished 

 with spines. Possibly it may be vulgaris, but it is much less 

 robust than that plant. In Perthshire I have met with at least 

 three species of Utriculai'ia, viz., minor, which is not very un- 

 common, but which I have only once found in flower ; inter- 

 media, which is much scarcer, and of which I have not found 

 the flowers ; and a third species (also not found in flower, and 

 hence difficult to refer to its proper position) much stouter than 

 minor, and with spiny teeth on the segments of its leaves. 

 This species is less (usually very much) robust than lowland 

 vulgaris and inhabits small lochs and pools on the hills, often 

 at an elevation of about 2000 feet, Loch Clunie being the lowest 

 situation in which I have seen it. I have not seen typical 

 vulgaris, nor indeed any species but minor (and in one locality 

 intermedia), in lowland Perthshire. 



In the Journal of Botany for May, 1876 (p. 142), Mr. F. M. 

 Webb has an article "on Utricular ia neglect a, Lehman ; and on 

 U. Bremii Heer, as a British Plant," in which he arrives at the 

 conclusion that U. Bremii (which was described from Switzer- 

 land) h'as been found in the Moss of Inshoch, Nairnshire, and 

 in Loch Spynie, in Moray. Referring to this plant, Dr J. T. 

 Boswell, in the " Botanical Exchange Club Report for 1876," 

 impresses on botanists visiting Moray the desirability of search- 

 ing for the Loch Spynie plant. I cannot say whether our 

 plant has any connection with U. Bremii, but it is desirable 

 that attention should be called to it, in hope that some one may 

 find flowers. 



Taken as a whole, the great feature of Loch Clunie is 

 the richness and variety of its aquatic vegetation. The 

 margins of the loch are occupied with great beds of Phragmites, 

 Scirpus lacustris, Equisetum pf //via tile, Ny/nplnca alba var. 

 mi?ior, Nuphar lutca, AlenyaJithes, Polygon urn amphibium, &c,
