Fern leaved lomatium is a California native perennial found in northern coastal, Klamath Ranges, and central Sierra Nevada Forest regions in deep mesic soils and wooded or brushy slopes at elevations of 150 to 2,000 meters. Flowering from May to July, this plant produces maroon-red or occasionally yellow flowers in compound umbels with 10 to 30 spreading rays. Growing 3 to 14 decimeters tall with a stout taproot and a base covered in scarious sheaths, it develops erect stems with few cauline leaves.

The fruit is an oblong-ovate structure 12 to 16 millimeters long with thick wings and obscure oil tubes.
