sometimes, however, to a depth of 3 or 4 feet, in which case the 
plants are much elongated and flowerless. 
Scirpus fluitans, L. IV., VI. Common in the peaty lochs of these 
Areas, and sometimes very abundant (fig. 25). 
Scirpus setaceus, L. VII. On sandy shores, scarce. 
Scirpns lacustris, X. “ I., II., III.,” IV., V., VI., VII. Widely distributed 
and abundant in both peaty and non-peaty lochs (figs. 23, 32, 33, 
89, etc.). 
Eriophorum vaginatum, L. “ I.” IV., VI., VII. Sometimes found upon 
the peaty shores of hill lochs. 
Eriophorum polystachion, L. ( = EJ. angustifolium, Roth.). “I., II.,” IV., 
V., VI., VII. More frequent than the last mentioned, especially upon 
the more or less peaty shores of lowland lochs ; less abundant amongst 
the mountains. 
Carex canescens, L. VII. Rare at the lochs. 
Carex disticha, Huds. VII. On sandy-muddy shores, scarce at the 
lochs. [In meadows at the head of Loch Ken and near Carlingwark 
Loch.— J. M‘A.] 
Carex paniculata, L. VII. Forms large tussocks, and occupies a 
considerable area of deep bog at the west end of Otterston Loch 
(fig. 103). [VI. Dowalton Loch. — J. M‘A.] 
Carex aquatilis, Wahl. “ I., II.,” IV., VII. Both the small and the 
large lowland forms (elatior, Bab.) are sometimes very abundant ; at 
the head of Loch Ken specimens over 6 feet high were observed. 
The appearance of this plant in Fife has been queried. It was first 
recorded there by Professor J. H. Balfour at Loch Fitty in 1862. 
There it still exists in abundance, especially at the west end of the 
loch, where it grows 3 feet high in the water and 1 foot high on the 
boggy shore. It has also spread to Burntisland Reservoir, but is 
likely to be destroyed there when the proposed alterations are 
carried out (fig. 104). 
Carex Goodenovii, Gay. “ I., II.,” IV., V., VI., VII. Widely distributed 
and often very abundant about the shores of both lowland and sub- 
alpine lochs ; on drier parts of the shores of the latter, very dwarf 
forms are frequent. By accidentally overlooking a sheet of notes, this 
plant was omitted from Areas I. and II. ( Proc . Roy. Soc. Edin., 
vol. xxv., pt. xi.). It is very plentiful, particularly in Area I. 
Carex flava, L. “ I., III.,” IV., V., VI., VII. The type and its varieties 
are frequent upon the shores of lochs, but seldom in abundance. 
Carex flacca, Schreb. “ II.,” IV., VII. Not uncommon, thriving chiefly
