Stebbins' harmonia is a rare (CNPS 1B.2) California native annual found in southern Klamath Ranges and northern North Coast Ranges Inland in serpentine slopes at elevations of 1,100 to 1,600 meters. Flowering from May to July, this plant produces white flowers with 4 to 6 ray flowers measuring 4 to 6.5 millimeters long.

Its leaves are primarily concentrated on the central stem and immediately proximal to branches supporting flower heads, with phyllaries that are densely covered in soft white hairs along folded edges. The fruit consists of ray fruits slightly bowed outward and disk fruits with plumose pappus scales 1.2 to 3.5 millimeters long.
