'''''Madia''''' is a [genus](/source/genus) of annual or perennial usually aromatic [herb](/source/herb)s with yellow flowers, in the tribe [Madieae](/source/Madieae) within the family [Asteraceae](/source/Asteraceae).<ref name=w>[https://www.biodiversitylibrary.org/page/41027931#page/142/mode/1up Molina, Giovanni Ignazio. 1782. Saggio sulla storia naturale del Chili  136–137, 354] text in Italian, footnotes in French and Latin</ref>

They are sometimes known as '''tarweeds'''. The species in this genus are native to western [North America](/source/North_America) and southwestern [South America](/source/South_America). The name ''Madia'' is derived from native [Chile](/source/Chile)an name ("Madi") for one of the members of the genus (''[Madia sativa](/source/Madia_sativa)'').<ref name=w/><ref>[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=119433 Flora of North America, Vol. 21 Page 303,  Madia Molina, Sag. Stor. Nat. Chili. 136, 354. 1782. ]</ref> Tarweeds derive their common name from the intense stickiness of the plant.<ref name=USDA>{{USDA}}{{cite web |title=Common Madia |url=https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_mael.pdf |website=USDA |access-date=28 June 2025}}</ref>

==Uses==
Tarweeds produce abundant seed, are agreeably aromatic and oily, and form an important part of the small seeds used in [pinole](/source/pinole). Tarweed and other seeds in pinole formed a staple food in the diet of the Indigenous peoples of the Pacific Coast. In particular, the seeds of gumweed ([''Madia elegans'' ssp. ''densifolia''](/source/Madia_elegans)) were among the most valued by the [Miwok people](/source/Miwok_people) for pinole. The [Hupa](/source/Hupa), [Cahuilla](/source/Cahuilla),
[Diegueño](/source/Diegue%C3%B1o), [Chumash](/source/Chumash_people), [Costanoan](/source/Costanoan), [Kawaiisu](/source/Kawaiisu), and [Maidu](/source/Maidu) tribes in California made pinole from ''Madia''species.<ref name=USDA/>

==Ecology==
The dark seeds ([achenes](/source/achenes)) of tarweeds are used as food by many birds and small mammals, including mourning doves, quail, blackbirds, finches, Oregon juncos, California horned larks, western meadowlarks, American pipits, sparrows, towhees, chipmunks, ground squirrels, and mice. Cottontail rabbits, ground squirrels, and chipmunks eat the plants.<ref name=USDA/>
