from an old tree or bush, and may be placed with those that 
are moderately hairy. Stooled bushes are usually, if not 
always subglabrous. Old trees may be subglabrous or quite 
densely hairy. E. F. Linton does not seem to have seen 
the $ of this variety ; I have seen only one tree in Middlesex, 
and one bush in Surrey. I congratulate the finder. — J.

Salix alba var. vitellina (L.) [S 742]. Planted left bank 
of R. Hiz, Hitchin, Herts., April 20, July 19, 1928. — J. E. 
Little. I agree. The yellow bark of the young twigs, the 
long catkins, and their long bracteoles during anthesis are 
good evidence of var. vitellina. I have for more than twenty 
years entertained the belief that this is a hybrid between 
S. alba and S. fragilis. The serratures of the leaves are 
intermediate, and the ovaries are much wider at the base 
than in S. fragilis. The latter in exposure often has yellow 
or red bark in the autumn and winter. — J. Fraser. 
Salix alba var. vitellina (L.) x triandra ? [549]. (See 
B.E.C.R., 1923, 404.) April 23, Sept. 17, 1928. A planted 
tree, Fairfield, Hitchin, Herts. Of 100 flowers examined 68 
had two stamens, 12 had three, and 28 had four stamens. 
But the proportions are variable. — J. E. Little. Mr. J. 
Fraser (in litt.) writes “ All the forms of the hybrid (i.e. 
S. alba x triandra) have leaves suddenly narrowed to the 
point, which is not long.” If the above naming be ruled out, 
the variable number of stamens has still to be accounted for. 
The flowers with four stamens generally have the filaments 
connate at the base in pairs. Nectaries two. — J. E. Little^ 
I agree. The leaves are better than those of my sheet from 
the 1923 gathering, as they are larger, and take more after 
the lanceolate-elliptic shape of a typical 5. triandra. The 
catkins are not so long as those of Surrey specimens of the 
ordinary S. alba var. vitellina (L.) I have them £ and $, with 
catkins two and a half to five inches long from trees and 
bushes, so that these seem to be shortened by the influence of 
S. triandra. I commend Mr. Little for his great assiduity 
in working out the number of stamens, which furnish valuable 
evidence. — J. Fraser. 
Salix pruinosa Wendland. Cult. Kew, Surrey. Catkins 
Mar. 17, leaves Sept. 29, 1928. Not a British species, but 
it is the 5. acutifolia Willd., recorded in Hooker and Arnott’s 
British Flora (1855), from Cleveland and Wensleydale,
