Chenopodium ficifolium Sm. [No. 427]. Wimbledon Park, 
Surrey, Oct. 9, 1928. This plant and C. polyspermum were 
formerly almost as abundant about Wimbledon as C. album, 
but have now been nearly extirpated by building. — H. W. 
Pugsley. 
Atriplex glabriuscula Edm. (Fruits). Aldeburgh, E. Suffolk, 
Sept. 17, 1928. — K. D. Little. Comm. J. E. Little. 
Polygonum heterophyllum Lindman. [Ref. Z 28]. East- 
fields, Mitcham, Surrey, Oct. 15, 1928. In these specimens 
there is not as much contrast between the two types of leaves 
as in the more typical plant. — J. E. Lousley. 
Polygonum aequale Lindman. [Ref. Z 19]. Eastfields, 
Mitcham, Surrey, Oct. 15, 1927. Not appearing quite typical, 
but the lax growth is largely due to the late date at which 
the plants were collected.— J. E. Lousley. 
Polygonum aequale Lind, x P. heterophyllum Lind. [Ref. 
Z 58]. Intermediate in flowers, fruit, and leaves, but with 
the influence of the last named parent predominant. Leg. 
ipse. Sandbanks, Poole, Dorset, Oct. 1927. — J. E. Lousley. 
Polygonum minus Huds. Ditch near Amberley Castle, 
W. Sussex, Aug. 19, 1928. — E. C. Wallace. I agree. The 
narrowly lanceolate-accuminate leaves are ciliolate, with 
fringed stipules that clasp the stem tightly. The small 
sepals have some small glands at the base, and the jet black 
nutlets are very glossy.- — J. Fraser. 
Polygonum nodosum Pers. [1277]. Ditch by Amberley 
Castle, W. Sussex, Aug, 19, 1928. — E. C. Wallace. Very 
nice specimens, beautifully prepared. — C. E. Salmon. 
Polygonum . [Ref. 1278]. Edge of dried-up pond 
near Blackbrook, Dorking, Surrey, Sept. 8, 1928. Is this a 
hybrid ? I cannot put it to either P. Persicaria, P. nodosum, 
or P. lapathifolium. — E. C. Wallace. Mr. Wallace suggests 
this may be a hybrid. If one compares the nuts of (1) P. 
Persicaria, (2) lapathifolium, and (3) nodosum ( maculatum ), 
it will be seen that in (1) the nut is circa 2\ mm. long x 2 mm. 
broad, is almost black, ovate, and tapers to apex without 
any obvious shoulder and equals or slightly exceeds perianth. 
In (2) the nut is larger, c. 3 mm. long x 2f mm. broad, and 
thus almost orbicular with a very obvious shoulder, almost 
black and equals or exceeds perianth. In (3) the nut is just
