SALIX 
To the same hybrid (S. alba x triandra ), White (op. at., p. 355) refers a Perthshire plant which he names x S. subdola. 
Of this, he gives a very unconvincing account. He states that “whilst the dwarf stature and general facies of the bushes 
incline me still to think that S. triandra and S. alba have both something to do with the parentage of this plant, 
more recently obtained leaves (from young shoots) strongly recall S. fragilis. It may be, therefore, possibly a form of 
[x] S. viridis [= .S. alba x fragilis], though that seems to me improbable ; or, perhaps, S. decipiens x alba (i.e., S. fragilis 
x S. triandra x S. alba).” The Rev. E. F. Linton regards x 5 . subdola White as a form of S. alba x fragilis. We have 
seen White’s specimen ; and it does not agree with the figure, cited above, of MM. Camus.]

Tree, attaining a height of about 20 m. Young branches long, weeping. Leaves remaining 
on the tree much longer than in any other of our deciduous trees, and indicating that the 
tree is from a region with a very different climate from our own (cf. Populus italica, page 9). 
Pistillate catkins on peduncles at least half as long as the catkins themselves, about 3 cm. long 
and 4 mm. broad, appearing with the leaves ; late March and April. Nectaries one to each 
pistillate flower. Style rather long. Stigmas more or less divided or emarginate. Ovaries 
subsessile, shortly stalked ; May. 
Planted, by the sides of rivers and ponds chiefly, in the lowlands of southern, eastern, and central 
England. Staminate plants are apparently unknown, but androgynous ones are said to occur. The hybrids 
A. alba x babylonica and A. babylonica x fragilis also occur as planted trees. 
Variously stated to be indigenous from the Caucasus to northern Persia, and in China.

Shrub about 4 or 5 m. high, or rarely a small tree about 8 or 9 m. high. Bark flaking 
off in autumn like that of the plane-tree ( Platanus ). Young branches glabrous. Stipules usually 
persistent, large especially on the coppiced shoots. Petioles about 1 — 2 cm. long, glabrous, minutely 
glandular at the top at least when young. Laminae variable, usually narrowly oblong-elliptical,
