pusillus, L., var. tenuisswuis, M. and K. — P. Graebner. These 
Brograve plants have a much more flattened stem than typical 
P. pusillus. The form was quite new to me, and Mr. Fryer did 
not know it. — C. E. Moss. This is very like a plant I gathered 
near Eye, and conspicuous by its flattened stem. Mr. Fryer 
thought it was new. — G. Claridge Druce. 
Potamogeto 7 i mtef rupius^ Kit. Brograve Level, Norfolk. Very 
brackish ditch, August 1909. — C. E. Moss. P. pectmatus, L., var. 
tenuifolms, M. and K. — P. Graebner. 
Zannichellia gibberosa, Reichb. Morden Common, Surrey, 
.\ugust 21, 1910. Examples collected at the locality recorded by 
me in ‘Journ. of Botany,’ 1910, p. 77. — C. E. Britton. A few 
only of the lower fruits on my specimen show the character. — G. 
Claridge Druce. Not so characteristic as my Hascombe (W. 
Surrey) sheet, which has many of the fruits muricate on both edges ; 
apparently this only occurs when they are nearly or quite ripe. — 
Edward S. Marshall.

No. 69]. Aberlady Bay, Haddington, v.-c. 82, August 13, 1910.

shall. 
Zostera najia, Roth, [ref No. 447]. Aberlady Bay, Hadding- 
ton, v.-c. 82, August 13, 1910. — McTaggart Cowan, fun- Right.

Scirpus Tabertiaano?ita>ius, Gmel. Marsh Gibbon, Bucks., Sep- 
tember 1910, Ambrosden, Oxon., August 1910. Both new county 
records and in stations (although in two counties) not more than

— G. Claridge Druce. 
Cladium Afarisciis, Br. Holme Moor, near Wiveliscombe, 
V. c. 5 S. Somerset, August 22, 1910. New for the vice-county. 
Plentiful over about an acre. — Edward S. Marshall. 
Carex divisa, Huds. Meadow near tidal river. By the Wye 
near Beachley, W. Glos., v.-c. 34, September 15, 1910. — W. A. 
Shoolbred. 
C. leporina, L., Rhizoma non repens ; utriculi longe rostrati 
marginibus alati ! — G. Kukenthal. I cannot at all understand 
this determination; our plant has no perceptible resemblance to 
C. leporma {ovalis. Good.), from which the inflorescence and tough.
