236 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Potamogeton coriaceus , Fryer ; P. lucens , coriaceus , Nolte. Firtrey 
Hall Farm drain, Welches Dam, Cambridgeshire, 6th August, 1888 
(No. 1,160 ).— Alfred Fryer. “Taking the plate in Reichenbach’s 
‘ leones,’ and a type specimen in Nolte’s herbarium (Herb. Mus. Brit.), 
Mr. Fryer’s specimens show the following differences, i.e. the leaves of 
the barren shoots in Nolte’s pi. have shorter petioles and leaves 
than Mr. Fryer’s specimens. The submerged leaves of the Cam- 
bridgeshire plant are also more gradually tapered and less undulate ; 
but there is no doubt Mr. Fryer is correct in naming them as the 
plant of Nolte, and his specimens are the best representation of the 
plant, other than Nolte’s own specimen’s, I have yet seen.” — Arthur 
Bennett. 
P. Zizii, Roth, 1827. Long Drove, Pidley Fen, Hunts, 19th 
August, 1888 . — Alfred Fryer. u P. angustifolius , Presl in Bertch 
et Presl, Rostlin, 1823, is probably Zizii (teste Fieber) but no 
specimens of Presl’s plant are in the herbarium of the German 
University at Prague, or of the Czech University. — Arthur Bennett 
P. zoster cefolius, Schum., Isis, Oxford, August, 1887.— G. C.

Eriocaulon septangulare , With. Bally nahinch, Co. Galway, July,

record; 4th September, 1888 . — Alfred Fryer. 
S. maritimus , L., v, compactus , Koch. Canvey Island, Essex, 
1888. If this be the variety required by the club, I may remark 
that, although scarce in the locality mentioned, I have seen it else- 
where. It seems confined to the marsh ditches in the flats, and does 
not occur, to my knowledge, by the riverside. — E yre de Crespigny. 
The varietal name of conglobatus, Gray, in ‘ Nat. Arr.’ precedes that of 
Koch, 1844, or Reichb. Although figured in Krock’s ‘FI. Silesia,’ 
it has no binomial name given it there. — Ed.
