Salix triandra
''Salix triandra'', with the common names almond willow or almond-leaved willow, is a species of willow native to Europe and Western and Central Asia. It is found from southeastern England east to Lake Baikal, and south to Spain and the Mediterranean east to the Caucasus, and the Alborz Mountains. It usually grows in riparian habitats, on river and stream banks, and in wetlands.〔Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4.

==Description==
''Salix triandra'' is a deciduous shrub or small tree growing to tall, usually multistemmed, with an irregular, often leaning crown. Young bark is smooth grey-brown, becoming scaly on older stems with large scales exfoliating (like a plane tree) to leave orange-brown patches. The leaves are broad, lanceolate, 4–11 cm long and 1–3 cm wide, with a serrated margin; they are dull dark green above and green to glaucous-green below, with a 1–2-cm petiole with two conspicuous basal stipules.
The flowers are produced in catkins in early spring at the same time as the new leaves, and pollinated by insects. They are dioecious, with male and female catkins on separate trees; the male catkins are 2.5–8 cm long, the female catkins 2–4 cm long. The male flowers have three stamens, a useful identification feature with most other willows having two or five stamens.〔〔
