Ceratophyllum demersum Linn. Specimens in flower from 
Dorking Millpond, Surrey, July 21, 1929. Gathered in the 
company of the late C. E. Salmon who remarked at the time 
that he had never seen this plant fruiting in the Millpond. 
No fruits were seen when I visited the pond some two months 
later. — E. C. Wallace. Yes. — W. H. Pearsall. Yes. — H. S. 
Thompson. Correct ; the leaves are only once or twice 
forked. — J. Fraser. Correct ; no fruit, but it can be dis- 
tinguished by the four segments of the bifurcate leaf. — 
I. M. Roper. Correct ; good specimens but without ripe 
fruit. — H. W. Pugsley. 
Ornithogalum pyrenaicum Linn. Trindledown Copse, near 
Froxfield, Wiltshire, July 5, 1912. — C. P. Hurst. Comm. 
S.L.B.I. 
J uncus triglumis L. Perthshire (1 specn. Argyll.) — W. A. 
Shoolbred. Comm. Nat. Mus. of Wales. 
Typha angustifolia L. Marsh ditches about New Romney, 
E. Kent, July 10, 1930. — E. C. Wallace. Yes, good examples 
of this. — W. H. Pearsall (and others). 
Damasonium Alismci Mill. Pond near Guildford, Surrey, 
Aug. 7, 1930. — R. J. Burdon. Presumably from Briton’s 
Pond, Stringers Common. This plant is getting scarce in 
Surrey. — E. C. Wallace. 
Potamogeton coloratus Horneiu. Ditch on Ken Moor, N. 
Somerset, Sept. 10, 1930. — H. J. Gibbons and J. W. White. 
The habit of this pondweed is variable, leaning sometimes 
towards P. lucens or to P. alpinus. — J. W. White. Correctly 
named. As many of the upper leaves are 80-85 mm. x 30 mm. 
they would come under Hagstrom’s f. grandifolius. Irish 
examples (Portarlington, July, 1896, R. L. Praeger) possess 
leaves 95x56 mm., and the English fens often produce even 
longer leaves, up to 150 mm. As a general rule the apex of 
the leaves of this species shows little pointing, but occasionally, 
as in these specimens, some of the upper leaves are markedly 
cuspidate. — W. H. Pearsall. , 
Potamogeton alpinus Balb. var. Palmeri Druce. In deep 
water under a small bridge over the Basingstoke Canal, 
near Odiham, N. Hants, Sept. 13, 1930. — E. C. Wallace. 
These line specimens are very acceptable. They are un-
