Parryella filifolia, the common dunebroom,[2] is a species of flowering plants in the family Fabaceae.

[3][4] It is native to Arizona, Colorado and New Mexico.

[5] Its ashes were sometimes used by members of the Hopi tribe in the maize nixtamalization process  and helped to retain the blue color of cornmeal used to make piki bread.

[6] The genus name of Parryella is in honour of Charles Christopher Parry (1823–1890), who was a British-American botanist and mountaineer.

[7] The genus and the species were circumscribed by John Torrey and Asa Gray in Proc.
