<5. fragilis L. (Broad leaves) [629.] Digswell, Herts., June 
13, 1925. — J. E. Little. This is identical with No. 589, and 
some of the shoots show the broad stipules of S. triandra. I 
name it S. fragilis x triandra ( alopecuroides Tauseh.). The $ 
S. fragilis has always been a scarce tree, for Smith had never 
seen it. The above named hybrid is most often $ . — J. Fraser. 
S. fragilis L. $ . Form producing a proportion of branched 
catkins, about one to each shoot. From a tree growing on the 
Surrey-Hampshire border at Hammer, near Haslemere, May 23, 
1925. I found one trifid catkin, the rest were normal or bifid. — 
I. A. Williams. It is S. fragilis x triandra , which is widely dis- 
tributed in Surrey. Besides the bifurcate catkins, the flowers 
are often very erratic, and additional stamens and ovaries some- 
times grow from the nectaries. The primordial leaves and catkins 
are veiy shaggy when half grown — too hairy for S. fragilis. — 
J. Fraser. 
S fragilis L., Subsp. decipiens (Hoffm.). Redhill Marsh, 
Surrey, v.c. 17, May 17 and August 16, 1925. [Ref. No. 562.] 
The leaves of Hoffmann’s species bear a considerable resemblance 
to those of S. fragilis , and the twigs are also very brittle in spring ; 
but the tree is very much smaller, and the twigs very short on 
old trees. Only the $ plant is known for certain in Britain, 
and the catkins never more, perhaps, than six on a twig, usually 
1 — 3. — J. Fraser. 
S. alba L. $ . [622.] Purwell, Hitchin, Herts., May 12 and 
July 9, 1925. — J. E. Little. Yes; S. alba so far as the leaves 
show their characters in July. I like to gather the leaves of this 
species in September, when they show whether or not it is the 
var. caendea (Sm.). Even Essex trees of it can be as hairy as 
this in July. — J. Fraser. 
S. alba x pentandra Chilmead Farm, Redhill, Surre}', v.c. 
17, May 17 and July 25, 1925. The specimens are from a large, 
wide spreading bush, which may have been cut down some years 
ago. — J. Fraser. 
S. aurita x cinerea. Mitcham Common, Surrey, v.c. 17, Sept. 
1925. These specimens show very late catkins taken from a bush 
1 believe to be S. aurita x cinerea. I have seen no explanation 
of them. Are they especially characteristic of hybrids ? I have 
them from S. undulata Ehrh. — D. G. Catcheside. I should prefer 
to call this S. cinerea L. The hybrid takes on many and curious 
forms, being often more like one parent than the other. I like
