Callitriche palintris^ Linn. Old brickpit, Church Stretton, 
Salop, v.-c. 40, July 18, 1909. — S. H. Bickham. In C. vernalis, 
Koch, the fruit is longer than broad; here it is broader than long, 
and the lower leaves have the emarginate hooked tip characteristic 
of C. intennedia^ Hoft'ni. (Jiamiilata, Kuetz.), to which I feel sure 
that Mr. Bickham’s plant must be referred. The name C. palustris^ 
L., should be dropped, as being quite vague and uncertain of 
application ; just as in the case of Rosa viilosa, L., cited as an 
e.xample in the Vienna Code. — E. S. Marshall. Hegelmaier in 
his monograph of the genus insists that ripe fruit is essential for 
correct determination of specimens — the fruit on these is not ripe. 
C. palustris has the fruit distinctly contracted from the middle 
to the base, and the section is very different. I agree with 
Mr. Marshall that it is C. intermedia, Hoffm. — A. Bennett. 
Astrantia major, Linn. Wood near Stokesay, Salop, v.-c. 40, 
July 20, 1909. — S. H. Bickham. I see no reason against its being 
native ; aiiparently it occurs plentifully in two or three woods of 
long standing. — E. S. Marshall. I doubt its being native. — • 
G. C. Druce. 
Ammi majiis, L. Near Letcombe Camp, on the downs above 
\V^antage, Berks., v.-c. 22, Oct. 16, 1909. — H. J. Riddelsdell. 
Correct. — S. H. Bickham, A. Lev, G. C. Druce. 
Daucns Carota, \.. Pasture near Seer Green, Bucks., v.-c. 24, 
Sept., 1908. I thought this autumnal condition might be acceptable 
to members. — G. C. Druce. 
Sambucus nigra, Linn. Seedlings, to show the simple early 
leaves. Walton, S. Lancs., v.-c. 59, Sept. 1909. — J. A. Wheldon. 
Galium verum, L., var. littorale, Breb. Sand hills, Wallasey, 
Cheshire, v.-c. 58. July, 1909, and sands, Cleethorpes, Lancs., July, 
1909. — E. and M. D. This is the usual sand-dune and seaside 
form and is I think correctly named as above. ^Vhether it is var. 
maritimum, DC. 1 am not sure, but suspect it is not extreme 
enough. — E. Drabble. 'Lhis agrees exactly with Rouy’s descrip- 
tion ; but it also corresponds with the description in the Prodromus 
of var. maritimum, DC. (‘ El. Er.,’ iv. 248), first observed in Brittany, 
which is an earlier synonym, and supersedes de Brebisson’s name, 
— E. S. Marshall. Correct. — G. C. Druce, A. Ley. 
Galium erectum x verum. Woodwalton Een, Hunts., v.-c. 31, 
Coll. E. W. LIunnybun, Aug. 26, 1909 ; Comm. S. H. Bickham. 
Mr. Hunnybun states that G. Mollugo does not grow' there. Mr, 
Druce passed all the sheets. — S. H. Bickham.
