S. cinerea x viminalis $ [510]. Spinney near Sootfield Green, 
Offley Holes, Herts., May 2 and Sept. 4, 1922. See W.E.C.R. 
1921, p. 182. Comparing the wood under the peel of [510] with 
that of [504], it will be seen that the striation in the former is 
well marked ; in the latter there is no evident striation. — J.E.L. 
Correct, I should say. — W.H.P. I quite agree to this, which is 
a form of the polymorphous hybrid S. cinerea x viminalis , many 
or most of which have originated in Britain. — J.F. 
S. cinerea L. 1 Edge of outlet from Esthwaite Lake at Ees 
Bridge, N. Lancs., v.c. 69 b. FIs. April 18, Is. Sept. 30, 1922. — 
W. H. Pearsall. S. aurita x cinereal — E.F.L. I consider this 
quite an ordinary form of the species. The catkins are small, 
but they are very imperfectly fertilised. — J.F. 
S. cinerea L., f. oleifolia (Sm.). Ditch bank, Wraxall, N. 
Somerset, v.c. 6, April 13 and Aug. 23, 1922. — Ida M. Roper. 
Probably S. aurita x cinerea. — E.F.L. This much resemldes 
forms common on our lake margins, one of which I sent in this 
year tentatively labelled S. cinerea ? In Miss Roper’s plant there 
is little evidence in the foliage — except the narrow ly-reflexed 
margins — of the presence of aurita. The catkins, however, are 
very small, and their ovaries less subulate and more nearly 
cylindrical than those of cinerea. The ovaries too are evidently, 
though very shortly, styled ; but this is a character frequently 
found in the hybrid aurita x cinerea , and I am inclined to this 
determination in the case in question. — W.H.P. Not distant 
from Smith’s S. oleifolia in size and shape of leaf ; but teeth too 
large, and I have rejected quite a number of similar ones. My 
specimens, both $ and $ , have a close and beautifully netted 
venation with very rusty hairs, the catkins being large. I prefer 
to call this simply S. cinerea L., a very polymorphic species apart 
from hybrids. — J.F. 
S. cinerea L., abnormal var. Field near Salt Hill, Fishbourne, 
Sussex, v.c. 13, March 29 and July 10, 1922. — R. J. Burdon. 
S. cinerea , androgynous form, in the main, with a strain in it, I 
think, of S. aurita . — E.F.L. This condition is not a variety. I 
have always presumed it to be galled by a species of mite 
( Eriophyes ). It is what is termed androgynous. The stamens of 
the $ plant are converted into very long-stalked ovaries more or 
less perfect, but presumably never fertile This monstrosity 
occurs in S. aurita, S. cinerea, S. caprea . — J.F. 
Populus tremula L. $ Bank of Avon, Bristol, N. Somerset, 
v.c. 6, March 11 and Oct. 20, 1922. The staminate plant is very 
rare in Somerset. — Ida M. Roper. In every way typical. — J.F.
