rot(nnu{ietuii filifonnis Pers. 90, Angus; Jialgavies Lofli, near I or- 
far, lOtli July 1950. — Miss U. K. Duncan. “ Correct.” — J. E. Danjjy 
and G. Taylor. 
(larex vuipinoidea Miclix. 17, Surrey; damp hollow, Tadwortli, 1st 
and 16th July 1950. The plant was discovered here by C. T. Prime Avho 
sent specimens to me for identification at the end of June 1950. There 
were about twenty large clumps, each of some 200 culms, and at the 
time of my first visit the hollow was dry and the culms erect with bright 
green spikes. On July 16th the spikes were turning yellow and the 
clumps sprawling and standing in about a foot of water. No other aliens 
were observed in the vicinity and judging from the size of the plants it 
seems likely that it had been established in this closed community for a 
considerable time. It is difficult to suggest a likely soiii’ce of introduc- 
tion of a North American sedge to this habitat, but U.S.A. foi'ces were 
in the district during the war and may have brought the fruits with 
their stores or vehicles. For a note on previous occurrences in Britain 
see Lousley, B.E.C. 1937 Hep., 459, 1938. — J. E. Lousley. “ Yes, good 
complete specimens of Carex vuipinoidea Michx., a North American 
sedge which Mr. Lousley found near Farnborough, Mh Kent, in 1937. 
It was first found in Britain in 1880 on the banks of the Thames at 
Kew.” — E. Nelmes.
