Polygonum dnmetorum Linn. Most luxuriant in a copse 
near Henley Park, near Normandy, Surrey, Sept. 1, 1929. 
E. C. Wallace. A good find. In my experience it does not 
appear a second year in the same spot, though it fruits abun- 
dantly. — J. Fraser. Excellent fruiting dumetorum. — E. 
Drabble. 
Polygonum dumetorum L. [No. 463]. Wimbledon Wood, 
Surrey, Sept. 21, 1929. This plant was distributed from this 
station in 1924, but a few later specimens may be acceptable. 
The habitat is now being destroyed by building. — H. W. 
Pugsley. 
Polygonum minus Huds. [A. 71.] Dried up pond on W^eston 
Green, Thames Ditton, Surrey. August 17, 1929. — J. E. 
Lousley. 
Polygonum mite Hook. (P. laxiflorum Weihe. [A. 68]. 
Very damp ground by Thames, near Teddington, Surrey. 
Sept. 7, 1929. — J. E. Lousley. Yes, P. mite, according to seed 
characters. — E. C. Wallace. I agree, the leaves, stipules and 
sepals are right. — J. Fraser. Yes ; fruits 2\ mm. in length, 
much larger than those of P. minus var. datum. — E. Drabble. 
Polygonum petedicale Stokes. Pond near Guildford, Surrey. 
Aug. 25, 1929. — R. J. Burdon. Yes, I gathered this plant a 
week later at Briton’s Pond. See Report, Vol II, page 553. — 
E.C. Wallace. 
Polygonum Persicaria Linn. (A. 70) Moist ground near 
Thames, Bourne End, near Cookham, Bucks. Aug. 25, 1929. 
Ocrea close, fringed. Perianth smooth. Perhaps var. elatum 
Gren. et Godr. I should place this under the var. biforme 
(Wahlenb.) Fries. (= var. elatum G. & G.) although it is 
not very typical. — A. E. Wade. 
Polygonum lapathifolium Linn. [A. 69]. Waste ground by 
Teddington Lock, Surrey, Sept. 9, 1929.— J. E. Lousley. P. 
lapathifolium var. viride forma latifolium Asch. and Graebn. 
— A. E. Wade. The material is young, but by a couple of 
fruits, which are small, and concave, I should say this is 
rather P. maculatum (Trim, and Dyer) Bab. (P. nodosum auct.) 
But there is, as sometimes occurs in this plant, an absence 
or at least great scarcity of glands upon the stalks. In P. 
lapathifolium the racemes are obtuse-tipped ; in the present 
plant they are tapered upwards, and the flowers have a rosy 
tinge, instead of the (usually) white turning green of P. 
lapathifolium .
