==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 (stipules) 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.<ref>{{Cite web|title=Drosera linearis Goldie|url=http://www.worldfloraonline.org/taxon/wfo-0000945999|access-date=2020-12-15|website=www.worldfloraonline.org}}</ref><ref name="CoffinPfannmuller1988">{{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}}</ref>
==Distribution and habitat== ''Drosera linearis'' range is centered around the great lakes region with scattered populations in western Canada and the maritime provinces. 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; where it grows in minerotrophic water originating from groundwater or nearby uplands.<ref>{{Cite journal|date=October 1925|title=The Name "United States of America"<xref ref-type="fn" rid="fn1"><sup>1</sup></xref>|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}}</ref> Because of its rareness and its restrictive habitats, it is listed as a threatened species in Minnesota.<ref name="CoffinPfannmuller1988"/>
