Lomatium triternatum var. macrocarpum

Large fruited lewis' lomatium

Family: Apiaceae · Type: perennial · Native

Large fruited lewis' lomatium is a California native perennial found in the Klamath Ranges, northern Coast Ranges, and Great Basin in sagebrush-juniper and pine woodland habitats at elevations of 200 to 1,500 meters. Flowering from April to July, this plant produces white to cream-colored flowers in delicate umbels characteristic of the Lomatium genus. Growing with slender stems 10 to 40 centimeters tall, it has a delicate, branching structure emerging from a deep taproot. Its finely divided leaves are ternately compound, with each leaflet deeply dissected into narrow, thread-like segments. The fruit is notably large, reflecting its varietal name, with densely puberulent ovaries that help distinguish this variety.
