Mentha arvensis Linn, forma. Banks of stream near 
Houghton Bridge, Amberley, West Sussex, Aug. 9, 1930. 
[Ref. B 30]. — J. E. Lousley. Correctly named. These large 
specimens are sometimes mistaken for M. sativa, but the 
short calyx teeth determine 31. arvensis. The thinly hairy 
state is due to ample moisture. — J. Fraser. 
Mentha arvensis L. var. agrestis (Sole). Cheverell’s Farm, 
Botley Hill, Surrey, Sept. 2, 1929. The principal features of 
this Mint are the sub -rotund, shortly stalked, very hairy 
leaves, that are much wrinkled before pressure in drying. — 
J. Fraser. 
Marrubium vulgare Linn. Sandhills at New Romney 
Warren, East Kent, July 11, 1930. — E. C. Wallace. A plant 
that seems to like the manure of rabbits and other animals, 
judging by its usual habitats. — J. Fraser. I have seen this 
plant about rabbit holes in Surrey, Somerset, Worcestershire 
and at Romney Warren in Kent. — E. C. Wallace. 
Polygonum viviparum L. Winch Bridge, Teesdale, Durham, 
June 3, 1903. — A. 0. Hume. Comm. S.L.B.I. 
Thesium Jmmifusum DC. (1) Chalk hill, above Bratton, 
N. Wilts., June 21, 1930. — H. S. Thompson. (2) Chalky turf 
on the Sheep Leas, Horsley, Surrey, July 27, 1930. — E. C. 
Wallace. 
Euphorbia hiberna L. East Lyn Valley, N. Devon, July 
8, 1930. — H. W. Pugsley. 
Betula alba L. and B. pubcscens Ehrh. ? for confirmation. 
Sharpham Peat Moor, N. Somerset, June 14, 1930. Several 
old trees of the former, with large leaves irregularly serrate, 
grow at the border of a field by the rough road. — H. S. 
Thompson. Seems to me to be B. j^ubescens var. glabrata 
Wahl. The young shoots and leaves are pubescent, the old 
ones are glabrous in both cases. The bracts of the $ catkins 
have the side lobes erect. — J. Fraser. 
Salix cinerea X viminalis f . ferruginea G. Anders. [Ref. 441 ]. 
Chevingum Farm, Godstone, Surrey. The very short and 
thin pubescence, turning rather rusty in autumn, or after 
being dried some years, I attribute to S. cinerea. Wimmer 
quotes an English specimen of S. ferruginea G. Anders, under 
S. cinerea X viminalis. — J. Fraser.
