'''''Drosera linearis''''', commonly called the '''slenderleaf sundew''',[{{PLANTS|taxon=Drosera linearis|symbol=DRLI|accessdate=7 July 2009}}] is a [sundew](/source/sundew) found in the [Great Lakes region](/source/Great_Lakes_region_(North_America)) of North America, in Canada and the United States, such as [Michigan](/source/Michigan), and in [Montana](/source/Montana). It is usually no more than four inches tall.[D'Amato, P. 1998. ''[The Savage Garden: Cultivating Carnivorous Plants](/source/The_Savage_Garden%3A_Cultivating_Carnivorous_Plants)''.

==Description==
''Drosera linearis'' is a herbaceous perennial with gland-tipped hairs covering long linear leaves. Plants form rosettes that are 6–15 cm wide. The stalks ([stipule](/source/stipule)s) of the leaves are 5 mm wide and hairless. The leaf blades are linear-shaped, 1–6 cm long, and 1.5–3 mm wide with edges lined with hair-like glands. The flower scapes are hairless, 6 to 13 cm long, ending in 1 to 4 white flowers. The flowers are 6–8 mm wide with obovate shaped petals. The seed capsules are 4–5 mm long and when ripe have black, oblong-obovoid to rhomboidal-shaped seeds that 0.5–0.8 mm long. The seeds are densely and irregularly pitted with craters. The diploid (2N) chromosome count is 20.[{{Cite web|title=Drosera linearis Goldie|url=http://www.worldfloraonline.org/taxon/wfo-0000945999|access-date=2020-12-15|website=www.worldfloraonline.org}}][{{cite book|author1=Barbara Coffin|author2=Lee Pfannmuller|title=Minnesota's Endangered Flora and Fauna|url=https://books.google.com/books?id=wfWNq91AjeoC|year=1988|publisher=U of Minnesota Press|isbn=978-0-8166-1689-3|page=88}}]
==Distribution and habitat==
''Drosera linearis'' range is centered around the [great lakes](/source/Great_Lakes_region) region with scattered populations in western Canada and the [maritime provinces](/source/The_Maritimes). It is rare over most of its range, and only locally common in specific habitats. It is found in remote peat-lands in the northwestern and north central part of [Minnesota](/source/Minnesota); where it grows in minerotrophic water originating from groundwater or nearby uplands.[{{Cite journal|date=October 1925|title=The Name "United States of America"1|url=http://dx.doi.org/10.1086/ahr/31.1.79|journal=The American Historical Review|doi=10.1086/ahr/31.1.79|issn=1937-5239|url-access=subscription}}] Because of its rareness and its restrictive habitats, it is listed as a [threatened species](/source/threatened_species) in Minnesota.
