528 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Rumex acut-us , L. On a small common by the Straight Mile, near 
Dunchurch Avenue, Warwickshire, 20th July 1896, among a dense 
growth of R. crispus and R. obtusifolius. No other docks were present, 
and its position in conjunction with its coarse growth and apparent 
sterility, both of pollen and most of the fruit, strongly confirm its 
hybrid origin. — S. T. Dunn. 
Euphorbia Esu/a, L, ; var. Pseudo-cyparisias , Jord. Cote One, 
Egremont, Cumberland, May 1896. — Joseph Adair. 
E. exigua , L. ; var. retusa, (DC.) This variety apparently includes 
obtuse- and retuse-leaved forms. The species is common about 
Stockton, Warwickshire, 10th July 1896, and these forms (together 
with all the intermediate series) are found to be growing with it. — 
S. T. Dunn. 
Ul/zius. Near Besilsleigh, Berkshire, May 1896. Some large 
fine trees occur, and I refer them with some doubt to Ulmus glabra, 
Huds. ‘FI. Angl.,’ p. 95, 1762. Mr. J. G. Baker, when I pointed 
them out to him some years ago, agreed to the name. — G. Claridge 
Druce.

Hampshire, 16th May and 30th August 1895. — E. F. Linton. 
S. aurita x cinerea. Yeldersley, Derby, nth April and 8th July, 
1896. A curiously glabrate form, the main element being aurita. 
Uncommon so far as I have observed. — W. R. Linton. 
A. Caprea x cinerea. Edlaston Coppy, Derby, 23rd April and 30th 
June 1896. A rare hybrid in Derbyshire, this being the first 
pistillate plant that I have found. — W. R: Linton.

Willows,” as far as the material would go. — E. F. Linton.
