Hymenoxys brandegeei is a species of flowering plant in the daisy family known by the common names Brandegee's four-nerve daisy,[3] Brandegee's rubberweed or western bitterweed.

[4][5] Hymenoxys brandegeei grows at elevations of 2,800–4,100 meters (9,200–13,500 ft) in the mountains, often above timber line.

[6] The oldest available name for this plant is Actinella grandiflora var.

[7] In elevating the taxon to species status, Asa Gray opted to forgo the common but not mandatory custom of using the varietal epithet as a species epithet.

He chose instead to call the species Actinella brandegei.
