REPORT FOR I907.

mosana, Lej. — E. F. L. I belive this is E. Esula, L., but in the 
absence of fruit I cannot be certain. — C. Bucknall. This is 
E. Esula, L., a variable species. I have seen it in a similar 
habitat near Milverton, Leamington. — A. B. Jackson. 
E. sp. By the road near Marcham, Berks, doubtless alien, 
June 1907. — G, Claridge Druce. Appears to be the same as the 
last, and equally insufficient for determination. — C. Bucknall. 
Fagns sylvatica, L., var. I send out this as a somewhat 
remarkable leaf variety. Leaves uniformly much smaller, thicker, 
with veins on the under side much impressed; thicker and less 
sticky to the touch than in type. Small, very fructiferous trees on 
the north ridge of Moel-y-golfa, Montgomery, i8th July 1907. — 
Augustin Ley. 
Salix aurita x phylicifolia. Kinnelhead, Moffat, N.B., 19th 
July 1907. — W. R. L. 
.S', rugosa, Lief. Pond, Quenby, Leics., 14th August 1906 and 
April 1907. — A. R. Horwood. A. cimrea x vwiinalis, I believe. — 
E. S. M. Rather a narrow-leaved form, both of S. rugosa, Leefe, 
and of the hybrid S. caprea x viminalis. The older name is 
S. sericans, Tausch. — E. F. L. Not, ,I believe, the willow formerly 
known as S. rugosa, Leefe (a name now dropped), but another of 
the numerous hybrids between vimmalis dx\d the Caprece {Smithiana, 
Wind.). The so-called S. rugosa has broader and more oblong 
leaves than those in Mr. Horwood’s specimen. — D. Fry. 
A", hej'bacea x repens. By stream, about 1,400 ft., Glen Shee, 
E. Perth, y.-c. 89, 14th July 1906. — W. A. Shoolbred. 
S. myrsinites x nigricans, Glen Fiagh. — W. R. L. Yes ; 
nearer to nigricans, but there is good evidence of myrsinites . — 
E. S. M. 
Populus alba, L. Shirley, Derby, 20th April and 5th Aug. 
1907 : planted. — W. R. Linton. Correct. — E. S. M. 
P. canescens, Sm. Wyaston, S. Derbs., 19th April and 30th 
July 1907. — W. R. Linton. Yes; P. alba x tremula. — E. S. M. 
P. nigra, L. These autumnal leaves from the true plant which 
grows in Christ Church Meadow, Oxford, shall be supplemented by 
catkins next year. Sept. 1907.— G. Claridge Druce. I suspect 
that this is more probably P. canadensis. — E. S. M. Yes, the true 
nigra, which may be distinguished at once from the planted 
American tree by its burred trunk, denser foliage and leaves with 
a cuneate base _ and longer more acuminate points. — A. B. 
Jackson.
