fine. They have no feature of botanical interest beyond a number of such 

 plants as are contained in the other lochs of the neighbourhood, and such 

 need not, therefore, be independently described. 



The plants that flourish in and about this series of lochs, from Loch 

 Enoch to the Dungeon Lochs, are as follows : - Lobelia Dortmauna, 

 Littorella lacustris, Isoetes lacustris, Juncus fluitans, Myriophyllum alterni- 

 florum, Sparganium natans, and Potamogeton polygonifolius, all abundant; 

 Subularia aquatica, Callitriche hamulata, Utricularia vulgaris, U. intermedia, 

 Scirpus fluitans, Sparganium minimum, and Castalia speciosa, var. minor, 

 all more or less scarce. Characea3 are apparently scarce. Batracliospermum, 

 Ulothrix, Mougeotia, Zygnema, Dickieia, etc., are frequently very abundant. 

 Heleocharis palustris, Eriophorum vaginatum, E. polystachion, Carex 

 rostrata, C. Goodenovii, C. filiformis, and Equisetum limosum are all 

 abundant. Menyanthes trifoliata, Juncus eff'usus, J. lamprocarpus, J. 

 acutiflorus, J. supinus, Carex binervis, C flacca, var. stictocarpa, and 

 dwarf forms of Ranunculus Flammula, Caltha palustris, Cardamine 

 pratensis, and Hydrocotyle vulgaris are all more or less scarce. The follow- 

 ing are some of the most conspicuous Brj^ophytes that occur, either in the 

 water or clothing the rocks of the shores. A number are distinctly 

 terrestrial forms, yet they constitute such a feature of the shores and are 

 so inextricably associated with the loch that an enumeration of the flora 

 would be incomplete were they excluded : — Sphagnum sp. abundant on 

 boggy shores, Blindia acuta, Grimmia apocarpa, var. rivularis, Rhacomitrium 

 aciculare, Fontinalis antipyretica, Aulacomnium palustre, Pterygophyllum 

 lucens, Philonotis f on tana, Brachythecium rivulare, Hypnum fluitans, H. 

 revolvens, H. falcatum, H. scorpioides, H. commutatum, H. cuspidatum, H. 

 uncinatum, Dicranella squarrosa, Scapania undulata, S. sub-alpina, Nardia 

 compressa, N. emarginata, and N. scalaris. The foregoing species occur 

 more or less in water, and the following in drier situations : — Dichodontium 

 pellucidurn, Dicranella heteromalla, Dicranum fuscescens, D. Scottianum, 

 Grimmia apocarpa, Rhacomitrium lanuginosum, R. heterostichum, Hedwigia 

 ciliata, Trichostomum tortuosum, Orthotrichum rupestre, Bryum alpinum, 

 Mnium punctatum, Heterocladiura heteropterum, Pterogonium gracile, 

 Plagiothecium undulatum, P. elegans, Thuidium tamariscinum, Hypnum 

 cupressiforme, Frullania tamarisci, Pleurozia cochleariformis, Anthelia julacea, 

 Diplophyllum albicans, Mylia Taylori, Pellia calycina, P. epiphylla, etc. 



Loch Trool is 246 feet above sea level, and is 1.] miles long by ^ mile 

 wide, with a maximum depth of 55 feet. It is approached from Loch 

 Dee through a narrow, rugged, and trackless pass about 3 miles long, 

 This loch affords a splendid piece of highland scenery, which is probably
