Chenopodium rubrum L. Seedlings and young plants. 
Blagdon Reservoir, N. Somerset, Sept., Oct., 1933. I am 
doubtful if var. pseudo-botryoides H. C. Wats, is more than an 
inconstant form particularly abundant on dried up lakes and 
reservoirs. — H. S. Thompson. 
Chenopodium rubrum L. Minute half -inch seedlings with 
flower-buds, and one-inch cotyledons (drawn up seeking light) 
from adjoining crack in the mud. Barrow Gurney (top) 
Reservoir, N. Somerset, Oct. 6, 1933. — H. S. Thompson. 
The cotyledons of the smallest seedlings are evidently correct. 
It is difficult to be sure of them when obscured by a number of 
leaves. I prefer to paste down seedlings while fresh, on small 
pieces of white paper, to be mounted on larger sheets. By 
this plan one can spread out the cotyledons in their natural 
form, and they do not shrink in drying. — J. Fraser. 
Salicornia dolichostachya Moss. Bank of R. Axe, near 
Axmouth, S. Devon, v.c. 3, Sept. 27, 1933. — E. C. Wallace. 
Polygonum microspermum Jord. [Ref. E.12]. West End 
Common, Esher, Surrey, Aug. 17, 1933. See Report B.E.C. 
1932, p. 447. — J. E. Lousley. Apparently identical with the 
Polygonum from the same locality that was distributed by 
Mr. Lousley in 1932, and which was the subject of a lengthy 
note in Report B.E.C. 1932, where it was identified by Mr. 
Wilmott as P. microspermum Jord. The West End Common 
plant certainly agrees closely with Rouy’s description (FI. 
Fr. xii, p. 113) of Jordan’s P. microspermum especially in 
dimensions of nutlet (2x1 mm.). The description of this 
micro-species appears to have been first published in Boreau’s 
FI. Centre, ed. 3, p. 560 (1857). The plant distributed agrees 
very well with Boreau’s account. — C. E. Britton. 
Polygonum Hydropiper L. (1) Marshy meadow, Bye Mills, 
N. Somerset ; (2) Shapwick Peatmoor, Somerset, Aug. 22, 
1933. The latter in two distinct forms and colours. H. S. 
Thompson. Correct ; perianth very glandular. — J. Fraser. 
The striking differences exhibited by the specimens are no 
doubt due to variations in nutrition. — C. E. Britton. 
Polygonum [petecticale Stokes], Damp corner of pasture 
near Frenchay, W. Glos., Aug. 5, 1933.— H. S. Thompson! 
I agree. J. Fraser. This is P. Persicaria L. var. datum 
Gren. et Godr. — C. E. Britton.
