serratures. This form often loses much of its silkiness by August, 
and blackens in drying. There is nothing in the catkins of 
<S. repens to separate the forms. — J. Fraser. 
S. repens Linn., var. [Ref. No. 2849.] Epsom Com- 
mon, Surrey, Sept. 20, 1925.— C. E. Britton. Yes; S. repens 
Linn., f. fusca (Linn.). It produces rather long, ascending or 
sometimes suberect branches. The leaves are mostly nearly 
glabrous beneath, though usually silky white in May and June. 
I have it from Epsom Common. This is the second flowering — 
J. Fraser. This seems to be our more frequent form of the 
species, with oblong-lanceolate leaves, which by September have 
lost a good deal of the silky clothing on the underside. — J. E. 
Little. Distributed from S. Lond. Bot. Inst. 
S. Andersoniana x phylicifolia. Det. J. Fraser. Bank of 
ha-ha, Kew, Surrey, v.c. 17, May 16 and July 11, 1925. — D. G. 
Catcheside. The broadly oval leaves, with sub-cordate base, the 
blackening and the serrations running to the apex make this 
close to S. Andersoniana ; but the quick glabrescence and foliage 
of the twigs, as well as the pubescence of the ovaries, show the 
presence of S . phylicifolia. Not native in Surrey. — J. Fraser. 
Populus canescens Sm. $ Clifton, West. Glouc., March 20, 
1912. 9 Mangotsfield, West Glouc., March 26, 1913. Fol. 
Mangotsfield, July 1915.— J. W. White. Yes, characteristic 
P. canescens Sm., illustrated by well selected specimens. The 
female tree appears to be much rarer than the male —A. B. 
Jackson. Male and female catkins having been placed on the 
same sheet, I am not sure from the label of the origin of the 
leaves. The two pieces with leaves appear to be P. canescens, in 
which the nerves run out more distinctly to the tips of the lobes 
than in either P. alba or P. tremvla. The male catkins, which 
are without any stem-piece, are less silky hairy than in P. tremula, 
and are apparently P. canescens. On one leaf-piece the outer 
bud-bracts are partly glabrescent and shining at the tips ; this 
indicates P. canescens. The material might be a little more 
generous. When trees are dioecious it is safer not to put $ and 
2 on the same sheet. As Prof. Henry remarks of P. tremula , so 
also, both in P. alba and in P. canescens, glands (1, 2, or I think 
even 3) are occasionally found at the junction of blade and petiole. 
Mr. White’s leaves show them here and there. — J. E. Little.
