P. heterophyllum Lindm. var. — A. E. Wade. 
Polygonum lapathifolium L. Arable field, Lurgashall, 
West Sussex, Sept. 13, 1931. — G. M. Ash. The seeds are 
black in colour, and measured when fresh gave an average 
of 3mm. in length and 2.6mm. in breadth. Among them 
were a few trigonous ones. The inflorescence is rather short, 
very stout, obtuse-ended and erect. The perianth as well as 
the peduncle and pedicels are glandular. The pink-flowered 
form of P. lapathifolium is a good deal more unusual than the 
white turning green. — J, E. Little.

Salix triandra L. var. discolor And. Walton Moor, N. 
Somerset, Aug. 2 and 24, 1924. — J. W. White. As the leaves 
are glaucous beneath, this would come under var. discolor. 
N. J. Andersson says the glaucous form of the type is the 
wild one, and the green-leaved forms are the cultivated ones. 
— J. Fraser. 
Salix fragilis L. x<$. [739=768], Wallington Park, W. 
Norfolk. Leaves Sept. 23, 1927. FI. May 6, 1929.— J. E. Little 
and K. D. Little. This broad-leaved tree was determined by 
J. Fraser (See Report 1927, p. 418) as S. fragilis xtriandra : 
and by Herr R. Gorz (Brandenburg-am-Havel) as S. albax 
fragilis f. excelsior Host, sub-form discolor Kerner, sub-sub-
