Ericameria gilmanii is a rare North American species of flowering plants in the family Asteraceae known by the common names Gilman's ericameria,[3] Gilman's goldenbush,[4] Gilman goldenweed,[1] and whiteflower goldenbush.[5] It is endemic to California, where it has been found in and east of the southern Sierra Nevada, in Inyo County and on Owens Peak in northeastern Kern County.[6] It is a poorly known plant. There are six known populations, but only one has been observed in the last 20 years.[1] Updating as of 2023, several observations of at least two populations have been observed since 2011.

Ericameria gilmanii is a shrub growing up to 50 centimeters (20 inches) tall.[5] The foliage is aromatic.[3] The leaves are up to 1.2 centimeters (0.5 inches) long, curved backward, and glandular and resinous. The inflorescence is generally a single flower head, or sometimes more than one. The head has a bell-shaped base with curving phyllaries which are green to tan. The head contains a few white ray florets and has white disc florets at the center. The fruit is a hairy achene which is roughly a centimeter long including its pappus.[5]

Ericameria gilmanii grows in forests. The one known population is on United States Forest Service land. Other occurrences presumed to still exist are also on federal land.[1]
