Dichelostemma capitatum

Dichelostemma is a genus of seven species of flowering plants in the order Asparagales. The genus is native to the western United States, especially in northern California, but also east to Utah and north to Oregon and southern Washington.

The genus is placed in family Asparagaceae, subfamily Brodiaeoideae,^[1] in the latest Angiosperm Phylogeny Group classification (2009).^[2] The family used has varied considerably over time. Older sources may still place it in the in the family Liliaceae, in the order Liliales; earlier versions of the APG classifications used the family Themidaceae.

These plants grow from perennial corms that produce a raceme or umbel-like inflorescence. The flowers are bell- or tube-shaped and produce capsules with black seeds. The name, from the Greek for "toothed crown", refers to the stamen appendages.

Dichelostemma was once included as part of the genus Brodiaea.
