Other: The genus name, “Lomatium”, comes from the Greek "loma" for "bordered or fringed" and refers to the prominent winged fruits. The species name, “parryi”, honors Charles Christopher Parry (1823-1890), the first official botanist for the U.S. Department of Agriculture and a collector with the Pacific Railway Survey.
The family identification depends on anatomical details of fruits and seeds.
