564 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Polygonum maculatum , Trim, and Dyer. Taplow, Bucks, 1897. 
New county record. — G. C. Druce. 
Aristolochia Clematitis , Linn. Godstow Nunnery, Oxford, 1st 
July 1892. — G. Claridge Druce. 
Euphorbia hiberna , Linn. Near Lynton, Devonshire, August 
1896. — G. Claridge Druce. 
E. Cyparissias , L. Abundantly in a grassy field, between Lytham 
vicarage and the sea, Lytham, West Lancashire, May 1897. Apparently 
quite wild, and very abundant. I have not found this plant is 
anywhere cultivated in the neighbourhood. — J. Cosmo Melvill. 
“ Correct.” — E. G. Baker. 
E. exigua , Linn., var. retusa (DC.). Cornfield, Whitnash, 
Warwickshire, August 1897. — H. Bromwich. “ Scarcely; I have 
gathered much more retuse-leaved plants than this.” — W. R. Linton. 
Betula pubescens, Ehrh., var . parviflora, “ Wimm.” Near Tongue, 
West Sutherland, vice-county 108, 23rd July 1897.— W. A. Shoolbred. 
Salix triandra , L. forma. Orig. Banks of the River Ouse, St. 
Neots, Huntingdonshire; hort. Bournemouth, 14th April and 29th 
June 1892. The summer-flowering specimens, which are apt to be 
misleading, were thought to be, by the late Dr. White, S. triandra x 
fragilis. — E. F. Linton. 
S. alba , Linn., f. Grown from a plant supplied me by Mr. James 
Fingland, from Thornhill, Dumfriesshire; in the garden, Bournemouth, 
13th May and 5th July 1897. It had been named S. hexandra , Ehrh. 
(S. alba x pentandra , a form on the alba side) by the late Dr. White, 
but observation has convinced me that it is a form of A. alba , L., and 
it is given a place as such in the ‘Set of British Willows,’ Fasc., No. 79. 
— Edward F. Linton. 
S. cinerea , Linn. In the gorge of the Clydach River, between 
Bryn-Mawr and Clydach, in the neighbourhood of Abergavenny, 
Monmouthshire, nth June 1897 . — Charles Bailey. “Sent as a 
new county record for 35, but already recorded in the ‘Report of the 
Botanical Record Club’ for 1881. The specimen is not true S. 
cinerea , as in my opinion it is crossed with aurila , as evidenced by 
the leaf margin being more cut than in the type, and by the more 
prominent auricles.” — G. C. Druce. Also, the type from Gerrard’s 
Cross, Bucks. New county record. — G. C. Druce. 
S. aurita x Caprea. Edlaston Coppy, Derby, April and June 1894, 
Specimens from the same bush were so named in ‘ B. E. C. Report,’ 
1893, p. 423. — W. R. Linton. 
S. aurita x cinerea. Edlaston Coppy, Derby, April and June 
1894. This is mainly as above, though there may be a strain of 
Caprea in it. — W. R. Linton.
