The tips of the leaves at the base of the flowering catkins are 
discoloured. In 1923 the catkins expanded better, but remained 
small (1 — T8 cm. long). — J. E. Little. I suppose this is right; 
but the stipules are as narrow as in S. viminalis. — E.F.L. Probably 
correct, but the few ovaries on my sheet are too young for stable 
determination. — W. H. Pearsall. The few remaining linear, 
small and scarious stipules, soon fugitive, show this to be 
S. purpurea x viminalis (S. rubra Huds.). The leaves are longer 
than average specimens of S. hippoplidefolia (Thuill.), which I 
have seen, and they are glaucous green beneath, showing the 
influence of S. purpurea , as do the small slender catkins. — J.F. 
I do not see S. triandra in this, and should think it to be 
S. purpurea x viminalis ( S . rubra Huds.). Its stipules are linear- 
lanceolate and not in the least cordate. — H. W. Pugsley. 
S. alba var., coerulea x fragilis 5 [50 3 ] Little Wymondley, 
Herts., v.c. 20, June 11, 1922. — J. E. Little. I agree. — E.F.L. 
Yes — alba x fragilis. Most of the leaves are quite glabrous, but 
the few young ones present clearly show the alba pubescence. — 
W.H.P. I agree with this. The broad finely attenuate leaves, 
glaucous beneath, + silky when young, are quite characteristic. 
The length of the catkins is splendid, but they should have been 
gathered in May, as mine have opened their capsules, which are 
pedicellate and correct for the hybrid. — J.F. 
S. viminalis L. $ Hedgerow on peat, Greenodd, N. Lancs., 
69 b. FIs. April 17, 1922; Ls. Oct. 5, 1922. — W. H. Pearsall. 
Yes. — E.F.L. Shows splendid vigour on peat. I have seen 
S. cinerea, S. aurita, S. caprea, and S', repens on such formations ; 
but S. caprea least often. — J.F. 
S. caprea x viminalis ( S . mollissima Sm. $ [504] Swamp, 
right bank of River Hiz, between Grove Mill and Hyde Mill, 
Hitchin, Herts., v.c. 20, Feb. and June 1921, March and July 
1922. — J. E. Little. I think undoubtedly correct. — E.F.L. I 
would prefer to name this S. cinerea x viminalis ( S . Smithiana 
Willd.). The relative silkiness of the younger leaves would ally 
it with S. velutina Schrad. and S. holosericea Willd. The older 
leaves are assuming the rusty hue of S. cinerea. The narrow 
entire stipules, the pubescence of the buds, and the few short 
striations under the peel all point to S. cinerea x viminalis. — J.F. 
S. aurita x caprea 2 [505]. Yicarsgrove Wood, St. Ippolyts, 
Herts., v.c. 20, March 11, 1921, and Sept. 29, 1922.— J. E. Little. 
A small tree about 12 ft., with central stem about 3 in. diameter, 
and branches spreading all round like a standard plum tree.
