SALIX

glandular-serrate, up to about 8 or 9 cm. long and about 2 broad but rather smaller as a rule, 
dark green and shining above, glabrous. Catkins on short peduncles more or less leafy especially 
towards the base, variable in size and shape especially in continental examples, usually more or 
less divaricate at maturity, appearing with the leaves ; late March to early May, often a second 
crop of catkins in July and August. Bracts pale greenish yellow, rather hairy at least towards 
the base. Staminate catkins much longer than broad, cylindrical. Bracts obovate. Stamens 3 — 4, 
usually 3. Filaments hairy at the base. Anthers pale yellow. Pistillate catkins shorter, denser, 
and more elliptical. Bracts persistent, more or less elliptical or oblong-elliptical. Ovaries obtuse, 
pedicelled. Style short or absent. Stigmas divaricate, often emarginate at the apex. Capsules 
broad, glabrous, on more or less short stalks ; J une.

Young branches terete. Stipules narrower than in the other varieties, acute. Laminae rather 
cuneate at the base, acute, pale green underneath or rather glaucous when young. Smith {Eng. FI. 
iv, p. 167) states that the seeds have “a long dense snow-white woolly crown.” 
The commonest British form, occurring as far north as Ross-shire, but perhaps not indigenous north of 
Perthshire ; Ireland, co. Cork.

Young branches furrowed. Stipules broad. Laminae narrowly ovate, broad and rounded at 
the base, acute to acuminate, more or less glaucous underneath. Smith {Eng. FI., loc. cit .) states 
that its seeds have shorter and less abundant hairs than in var. genuina. 
Smith (loc. cit.) remarks that as an osier this is inferior to S. triandra. See also Smith (loc. cit.) for some careful 
remarks on the synonymy of S. amygdalina L. 
Rather rare ; we have seen specimens from Dorset, Essex, Suffolk, Huntingdonshire, and Warwickshire.

Shrub or small tree, up to about 3 — 4 m. high. Bark deciduous. Young branches terete. 
Stipules larger and more rounded. Laminae narrowly ovate, rounded at the base, more acuminate, 
pale or even subglaucous underneath, more yellow-green, thinner, shorter (about 37 to 5'o cm. long). 
Smith (loc. cit.) and Borrer (loc. cit.) agree that there is no remarkable difference in the staminate catkins; and 
pistillate plants have not been identified with certainty. 
Local, by stream-sides and in osier-beds, chiefly in southern, eastern, and central England, from Dorset, 
Glamorganshire, and Kent northwards to Shropshire and Derbyshire. 
S. triandra is locally abundant by stream-sides, in marshes and wet woods, in lowland localities ; 
from Cornwall and Kent northwards to the Border; southern and eastern Scotland, northwards 
to Perthshire and Ross-shire (? indigenous) ; southern and south-eastern Ireland. Often planted, 
as it is a valuable osier : many cultivated “ varieties ” are known to osier-growers. 
Europe, to 66° N. in Scandinavia and 67° N. in Russia, ascending to 1527 m. in the southern 
Alps; Asia Minor and the Caucasus to northern Persia (3000 m.), and from the Ural mountains to 
J apan.
