OCCURRENCE OF CLADIUM GERMANICUM, SCHRAD., IN BUTE. 167 
Occurrence of Cladium germanicum, Schrad., in Bute. 
By J. BatLantyNneE, Rothesay. 
[Read 30th October, 1894. ] 
In the north end of the Island of Bute, between the Black, Sight, 
and Mulich Hills, at an elevation of some 433 feet, is a sheet of 
water known as the Bull Loch. The loch is said to derive its 
name from bull-headed fish which have been caught in it. The 
name more probably refers to the bull trout, Salmo trutta, which 
could obtain easy access to the loch by the Lagganbeg Burn, which 
flows from the western end, and empties itself into the Kyles of 
Bute. It may be that char or alpine trout, Salmo salvelinus, are 
caught in it, and are termed bull trout, as is sometimes the case in 
Highland districts. 
Accompanied by Mr. James iiagle, M.A., Rothesay, I visited the 
loch for the first time on the 4th of August last (1894), and as we 
passed along its south side, we noticed a plant, which was new to 
us, growing amongst large quantities of the common reed, Phrag- 
mites communis, Trin. The plant we afterwards ascertained to be 
Cladium germanicum, Schrad., recorded in Hooker’s “Student’s 
Flora,” third edition, as obtained in Scotland in Sutherland, Berwick, 
and Wigtown shires only. As it has not previously been recorded, 
so far as we know, for the Clydesdale District and West of 
Scotland I have pleasure, at the request of Professor King, in 
submitting it for your inspection. 
It was found growing in from 2 to 3 feet of water, at a distance 
of 5 to 10 feet out from the margin of the loch, which is not 
sloping on this side but about 2 feet deep. The plants were 
growing on a soft mossy bottom in some eight or nine different 
spots, from near the outlet of the loch, along its southern side for 
a distance of a half to two-thirds of its length. 
Not knowing at the time that the plant is so rare in Scotland, 
we simply took specimens from the upper part of the stem, and 
therefore I cannot say anything about its root-stock; but the 
following is a description from the specimens obtained :— 
Stems obscurely trigonous, and 3 to 4 feet in length. Leaves 
_very long, the points triangular and about half the length of the
