40 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Mr. Druce kindly removed any doubts I had. The leaf ribbing is 
not that of A. repens, but intermediate between A. repens and 
jti 7 iceuni. The whole of the gathering sent is part of one large 
circular plant ; the procumbent stems ascending slightly at the 
panicle end are a well marked character. Spikelets 4-5 fld. — H. J. 
Riddelsdell. Coast near Arbroath, Forfkr, loth July 1904. — 
W. A. Shoolbred. Prof. Hackel confirms both of these. — J. G. 
Chara connivens, Braun. Hickling Broad, E. Norfolk, 5th 
July igoi. — G. R. Bullock-Webster. The club is much in- 
debted for the excellent specimens of this and a number of other 
Characese which Mr. Webster has so kindly contributed. 
C. polyacantha, Braun. Peat ditch, Walton Moor, North 
Somerset, loth Sept. 1904. A new plant for Somerset county. It 
has only been found in the Walton valley. Mr. Arthur Bennett 
says the growth is very small compared with that met with in the 
Broads of Norfolk and Cambs. ; but these peat ditches have rarely 
more than a foot of water, and they are raked out at short intervals. 
In consequence, this vegetation has little chance of becoming large. 
— Jas. W. White. “A small state.” — H. and J. Groves. 
C. haltica, Bruzel. Loch Stennis, Orkney, 6th Sept. 1902. — 
F. C. Crawford. “ A good supply of this interesting form, which 
is much closer to the typical Scandinavian haltica than the Cornish 
and Guernsey plants.” — H. and J. Groves. 
C. hispida, L. Peaty ditch, Ken Moor, N. Somerset, 17th 
Sept. 1904. Rare in the West country. — J. W. White.

four feet of water, 6th July, 1898.— G. R. Bullock-Webster. 
Lamprot/iamnus alopecuroides, Braun. In brackish water, clay- 
pit, near Hamworthy Junction, Dorset, roth August 1904. — G. R. 
Bullock-Webster. 
Tolypella. Canal, Brock, near Garstang, W. Lancashire, July 
1904.— Albert Wilson. “ r. prolifera, Leonh.” — H. and J. 
Groves.
