'''''Salix cinerea''''' ('''Grey Willow'''; also occasionally Grey Sallow) is a species of [[willow]] native to [[Europe]] and western [[Asia]].<ref name=rdm>Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. ISBN 0-901158-07-0.</ref><ref name=kic>Christensen, K. I., & Nielsen, H. (1992). Rust-pil (''Salix cinerea'' subsp. ''oleifolia'') - en overset pil i Danmark og Skandinavien. ''Dansk Dendrologisk Årsskrift'' 10: 5-17.</ref>
It is a [[deciduous]] [[shrub]] or small [[tree]] growing to 4-15 m high. The [[leaf|leaves]] are spirally arranged, 2–9 cm long and 1–3 cm broad (exceptionally up to 16 cm long and 5 cm broad), green above, hairy below, with a [[leaf shape|crenate]] margin. The [[flower]]s are produced in early spring in [[catkin]]s 2–5 cm long; it is [[plant sexuality|dioecious]] with male and female catkins on separate plants. The male catkins are silvery at first, turning yellow when the pollen is released; the female catkins are greenish-grey, maturing in early summer to release the numerous tiny [[seed]]s embedded in white cottony down which assists wind dispersal.<ref name=rdm/><ref name=kic/>
There are two [[subspecies]]:<ref name=rdm/><ref name=kic/>
*''Salix cinerea'' subsp. ''cinerea''. Central and eastern Europe, western Asia. Shrub to 4–6 m (rarely 10 m) tall, with smooth bark. Leaves densely hairy below with pale yellow-grey hairs; stipules large, persistent until autumn.
*''Salix cinerea'' subsp. ''oleifolia'' (Sm.) Macreight (syn. ''S. atrocinerea'' Brot.). Western Europe, northwest Africa. Shrub or tree to 10–15 m tall, with furrowed bark. Leaves thinly hairy below with dark red-brown hairs; stipules small, early deciduous.
There is some overlap in the distributions (not indicated in the map, right), with both occurring in a broad band north to south through France, and scattered specimens of subsp. ''cinerea'' west to Ireland, western France, and Morocco; scattered specimens of subsp. ''oleifolia'' occur east to the Netherlands. Specimens of subsp. ''oleifolia'' in southern Scandinavia are planted or naturalised, not native. Intermediate specimens also occur.<ref name=rdm/><ref name=kic/>
===Ecology===
It usually grows in [[wetland]]s. The two subspecies differ slightly in requirements, with subsp. ''cinerea'' generally restricted to basic marshland and fen habitats, while subsp. ''oleifolia'' is less demanding, occurring in both basic marshes and acidic bogs and streamsides.<ref name=rdm/>
