[Ref. No. 523]. Whyteleafe, Caterham Valley, Surrey. Leaves 
Sept. 14, 1924, catkins, April 19, 1925. S. caprea rather asserts 
itself in the large crenatures of some of the leaves. The finer 
serratures of most of the leaves, the partial glabrescence of the 
younger leaves, the small catkins, intermediate bracts, late date 
of flowering, and the twiggy habit of the bush, about five feet 
high, suggest S. aurita. — J. Fraser. 
S. cinerea x viminalis f. fe?ruginea (G. And.) [Ref. No. 495]. 
Tilburstow Hill, Godstone, Surrey. Leaves, July 6, 1924,. 
catkins, March 29, 1926. The short pubescence on the under- 
surface of the leaves, and the rusty or ferruginous colour when 
getting old, are my chief reasons for considering S. cinerea as one 
of the parents. — J. Fraser. 
S. Anclerssoniana x pliylicifolia $ [624]. Eelmire, near 
Jervaulx, N. Riding, Yorks., June 2, 1925. Alt. circ. 400 feet. 
— J. E. Little. Very close to S. Anclerssoniana Sm. ( nigricans 
Sm.) ; but since many of the leaves have entire points, and there 
is considerable polish on the one-year-old twigs, there is evidence 
that it is the hybrid S. Anclerssoniana x pliylicifolia. It is difficult 
to get the two species pure Avhen both grow together. — J. 
Fraser. 
S. Anclerssoniana x pliylicifolia $ [625]. Sowden Beck, E. 
Witton, N. Riding, Yorks., June 3, 1925. Leg. J. E. Little. 
Leaves, Oct. 18, 1926. Leg. Rev. G. Garrod. Yes; the green 
colour of the dried leaves, with entire points in many cases, and 
the amount of polish on the one-year’s shoots, indicate relations 
to S. pliylicifolia. The partial polish of the one-year-old shoots, 
and the quantity of pubescence on both sides of the young leaves 
and shoots indicate S. Anclerssoniana. — J. Fraser. By the kind- 
ness of the Rev. Canon G. Garrod, vicar of E. Witton, who 
gathered the leaves from the same two bushes, I have been 
enabled to complete the set. — J. E. Little. 
Populus canescens Sm. [672]. The Willows, Hitchin, Herts, 
v.c. 20, March 20, 1926.— VV. J. Housden. Comm. J. E. Little.’ 
A belated catkin enabled me to ascertain that the colour of the 
stigmas was light purple. Moss (Camb. Brit. Flora) states that 
the colour of the stigmas in P. canescens is yellow, and I believe 
he would regard the purple stigmas as evidence of hybridity 
with P. tremula. But Babington makes the stigmas of P. canescens 
purple. Such enlarged figures of the stigmas as I have seen are 
in general very inaccurate, being drawn hot from fresh bnt from 
shrivelled specimens. — J. E. Little.
