190 THE FRESH-WATER LOCHS OF SCOTLAND 
Diplophyllum albicans, Dum.^ IV. Sometimes covers the shore 
rocks of the hill lochs. 
EPIGONIANTHE.E 
Chiloscyphus polyanthos, Dum.^ V. Occasionally abundant on wet 
shores, and in the pools. 
Mylia Taylori, G7\ Benn.^ IV. On wet shore rocks, or on wet 
sandy shores. Large patches of it a^re occasionally abundant at 
the hill lochs. 
Nardia compressa, Gr. Beim.^ I., IV. Abundant on wet and 
submersed rocks, chiefly at the higher lochs. Sometimes a 
considerable area of submersed rocks and stones, to a depth 
of 3 feet, is covered with a dense carpet of this hepatic : instance 
Lochs Enoch, Dungeon, etc. 
Nardia emarginata, Ehrh., I., IV. On wet rocks and shores, and 
often in the water ; rather less abundant than the last- 
mentioned. Chiefly at the hill lochs. 
Nardia scalaris, Gr. Be?m., IV. On wet sandy-peaty shores of hill 
lochs ; often abundant. 
The following species are frequently found covering wet places 
about lochs, particularly on shady banks, under rocks, etc., in all 
the Areas, especially IV.: — Pellia calycina {Tayl.)\ P. epiphylla, 
Lindh. ; Conocephalus conicus, Diim. ; and Marchantia polymorpha, 
L, The last-mentioned is often found in the water of bogs as well 
as in drier places. 
Several species of Jungermannia are met with on the shores of the 
more elevated lochs, but always in small quantities. 
Amongst the mountains of Area IV. many lochs are bordered 
more or less by great rocks which are frequently covered in a most 
prolific manner with masses of lichens. A description of the flora 
of these lochs would be incomplete were it not, under such circum- 
stances, to notice the most predominant and conspicuous species of 
these lichens. They are as follows : — Platysma glaucum, Nyl. ; 
Cetraria aculeata, Fr. ; C. muricata, Ach. ; Parmelia lanata, Wallr. ; 
P. omphalodes, L. ; Alectoria jubata, Nyl. ; Lecanora tartarea, Ach. ; 
Sphaerophoron coralloides, Pers. ; Lecidea geographica, Sclioer.

Batrachospermum moniliforme, Rotli.^ I., IV. Abundant ; very
