It is widespread across much of Europe.[3] The species was first formally described by Carl Linnaeus in 1753.[4] DescriptionIt is a perennial herb with short runners.[5] The plant is 8 to 60 cm tall.[5] The leaves are lanceolate in shape, pointed, 2 to 8 cm long, with a single vein. They have no hair on top, but are woolly hairy below. The upper leaves become progressively shorter and narrower.[5] The flower heads are 6mm long. The bracts of the flower heads have a green centre, and chaffy brown edges. The florets are pale brown. The achenes are hairy with reddish pappus hairs.[5] It flowers from July until September.[5] References1. ^{{cite web |title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |archive-url=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archive-date=2015-01-25 |accessdate=2014-10-17 |deadurl=yes |df= }} {{Commons category|Gnaphalium sylvaticum}}2. ^[https://books.google.com/books?id=uHdXAAAAMAAJ&pg=PA403 An illustrated flora of the northern United States: Canada and the British possessions from Newfoundland to the parallel of the southern boundary of Virginia, and from the Atlantic ocean westward to the 102d meridian, Volume 3], 1898, p. 403. 3. ^Altervista Flora Italiana, Gnaphalium sylvaticum L. includes photos and European distribution map 4. ^{{IPNI|id=235193-1|accessdate=18 March 2009}} 5. ^1 2 3 4 {{cite book |last=Rose |first=Francis|authorlink=Francis Rose|title=The Wild Flower Key |year=1981 |publisher=Frederick Warne & Co|isbn=0-7232-2419-6 |pages=377–380}} External links
