Salix triandra x viminalis b. Trevirani Sprengel [Ref. 
No. 452;. Cultivated at Kew from Mortlake, Surrey, v.c. 
17. Catkins 17th April, leaves 15th August, 1927. By 
cultivating this hybrid I have been able to get rather better 
specimens than from the wild bush that gets broken by people 
gathering catkins they call palms. The stipules of the 
hybrid are very distinct from those of the hybrids S. rubra 
and S. undulata, which the leaves resemble. — J. Fraser. 
Salix [fragilis x cinerea ?]. Near Chertsey Bridge, 
Woking, Surrey. Catkins April 7, Leaves Sept. 22, 1927. 
I think this must be a hybrid, possibly with cinerea as there 
are pretty distinct striations on the stems. — W. Biddiscombe. 
Mr. Little says no such hybrid has hitherto been recorded : 
the leaf-piece sent to him is typical fragilis ; and after boiling 
out a couple of catkins and dissecting the flowers he finds 
the number of stamens was three. This might have been 
ascertained in five minutes when the catkins were fresh. 
The flowering piece is .S', triandra. “There is no record for 
such a hybrid as S. fragilis x cinerea nor S . cinerea x fragilis, 
so far as 1 can find. The specimens are 5. triandra x 
viminalis var. Trevirani Sprengel. However it is a first- 
class find for Surrey, where little of it occurs. The leaves 
are much broader, longer and more attenuate-acuminate 
than those of the sister hybrid, var. hippophaefolia Thuill. 
The small, very hairy catkins, and short stamens quite 
conform to those of all the specimens 1 have seen.’’ — J. Fraser. 
Salix fragilis L. (Det. J. Fraser) $ [714]. Gt. Wymondley 
Springs, Herts., June 11, Aug. 3, 1927.— J. E. Little. Many 
of the serratures approximate in pairs. The young leaves 
are more hairy than those of the more common state of 5. 
fragilis, but different trees vary in the amount of hairiness. 
The pedicels of the ovary are too long for the hybrid 5. alba 
X fragilis ; and the ovary itself is subulate and gradually 
attenuate into the short style. That of the hybrid is ovoid 
and ends abruptly below the style, in this respect agreeing
