Potamogetonpolygonifolius Pourr. Stream near Thursley, Surrey, 
June 27, 1925. — I. A. Williams. These plants came from exactly 
the same spot as those distributed last year as var. pseudo-fluitans 
and gathered in November 1924. In June 1925 the peaty stream 
was very low. The plants appeared fairly typical, though one or 
two shoots showed the long narrow leaves just beginning. On 
November 29 the long leaves were once more in great evidence, 
though not practically immersed as, I think, they were in 1924. 
This was probably due to 1925 being a drier season, and it seems 
as if the form distributed last year was an autumn leaf-form, 
which varies in extremity with the quantity of water and the 
swiftness of the current. — I. A. Williams. Correct. — A. Bennett. 
P. [lucens L.]. R. Wye, near Ross, Herefords., v.c. 36, Aug. 
1925. — F. J. Sheldon. A peculiar Potamogeton, gathered many 
years ago by the late Augustin Ley, and more recently by Miss 
Vachell. For many years both Mr. Fryer and I hesitated as to 
its name. But we came to the conclusion it is a form of P. an- 
gustifolius Bercht. et Presl. = P. Zizii Roth. The semi-fruiting 
is just the state in which it occurs in the Cambridgeshire Fens, 
although the foliage is much narrower. I have many specimens 
from Ross-on-Wye from the late Mr. Ley. — A. Bennett. 
Scirpus nanus Spreng. (1) Brackish lake near Criccieth, 
Carnarvonshire (submerged), Aug. 30, 1925, No. 416. ( 2 ) Muddy 
edge of salt lake, Pwllheli, Carnarvonshire, Aug. 20, 1925, No. 
417. — H. W. Pugsley. No spikelets could be found on this sedge 
in either of these localities in 1925, although at Pwllheli the 
plant was abundant over a considerable area, creeping extensively 
in the wet mud. — H. W. Pugsley. 
S. filiformis Savi. Near Barmouth, Merioneth, July 1923. — 
W. R. Sherrin. 
S. setaceus L. Near Barmouth, Merioneth, July 1923. — 
W. R. Sherrin. 
Eriophorum alpinum L. Near Gorner Gorge, Zermatt, Swit- 
zerland, Aug. 5, 1890. — H. Ward. Comm. W. R. Sherrin. 
Carex disticha Huds. Thursley Common, Surrey, June 27, 
1925. — I. A. Williams. A very rare plant in S.W. Surrey, I 
think. Dunn only records it from Hartmore Bottom. — I.A.W. 
Yes; not at all a common plant in Surrey. — C. E. Salmon. 
Yes; it would be a help if the underground parts were shown, 
or a note added as to their character. — J. E. Little.
