plant still occurs near Woodmansterne, Surrey. Hooker 
and others have regarded it as a naturalized escape, but 
this is not the view taken in the last edition of the London 
Catalogue.- — J. E. Lousley. If this conspicuous montane 
and subalpine plant had been known to grow wild in several 
English counties in the late 18th and early 19th century, more 
botanists would have mentioned it, whatever they con- 
sidered its origin. I can find no earlier British record than 
1837, Eng. Bot. Suppl. tab. 2799. “It . . . is remembered 
by the older people of the neighbourhood (Woodmanstone, 
Surrey) to have flourished truly wild in that locality for more 
than half a century.” Factors against it being more than a 
denizen in England are that it has appeared occasionally 
in several counties in increasing numbers, and that it was 
never recorded from near Henburv, in well-worked countrv 
close to Bristol, until 1901, and when first seen by the late 
C. Bucknall in 1910 there were quite 200 plants in several 
patches and covering a considerable area. See White, 
Flora of Bristol, p. 585.— H. S. Thompson. 
Potamogeton gramineus x lucens ( P . Zizii M. et K.) Alt- 
Ausseer See, Stiria, ca. 700 m., 21 viii 1926. — Dr. K. Rechinger. 
Correct. But the reference to M. et K. is not correct, as 
in their Deutsch. Flora, 1823, the name occurs only in the 
Index. They named it “ P. heterophyllus 8 latifolius.” 
And in 1824, Dr. Koch sent to De Candolle a set of specimens 
to show what they meant by the names in their Flora. A 
specimen is named “ P. heterophyllus 8 latifolius fl. nostr. 
ex Palatente. Mons. Koch 1824.” The first to take up 
Zizii as a valid name was Roth. (Enum. PI. Germ. 1, 531, 
1827). But this was antedated by Berchtold and Presl in 
their Rostlin, 1, p. 19, (1821) under the name of P. angusti- 
folius. This work was published in parts from 1819 to 1822, 
and the whole in 1823. It is written wholly in the Bohemian 
language. — A. Bennett. 
Potamogeton densus L. In fluvio Eischa, prope Enzersdorf, 
Austria, Juni 13, 1926. — Karl Rechinger. Correct. This form 
is between the type and var. rigidus Opiz. — A. Bennett. 
Cyperus fuscus Linn. Peaty ditch, Walton-in-Gordano, 
N. Somerset. Oct. 4, 1908. — C. Bucknall and Jas W. White. 
Eleocharis acicidaris Roem. and Schult. Canal Banks, 
Woking, Surrey, Aug. 27, 1927. — W. Biddiscombe. Correct. 
—A. Bennett.
