Lomatium (name refers to the bordered or winged fruit). Umbelliferae. Under this name of Rafinesque's are now separated the American plants that have been referred to Peucedanum. More recently, however, the name Cogswellia has been substituted, although lacking priority, because Lomatium is held to be too much like the older Lomatia of Robert Brown. Lomatiums are mostly W. American plants, of about 60 species, growing in dry soil. They are mostly low or stemless perennial herbs from tuberous or fusiform roots, and compound (ternate, pinnate or dissected) lvs. From Peucedanum the genus differs, according to Coulter & Rose, as follows: "Peucedanum consists of tall and branching mesophytic plants of low fertile meadows of the Old World, with several umbels, conical stylopodium, and solitary oil-tubes; while Lomatium consists of low xerophytic plants of acaulescent habit belonging to the arid regions of W. N. A., with usually single umbels terminating simple elongated peduncles, no stylopodium, and often several oil-tubes." Horticulturally, the lomatiums are of small value, and they have not been cult, sufficiently to have given rise to cultural forms. A few of the species have been offered by dealers in native plants. They seem to thrive well in dry exposed places. They are interesting for the front row of hardy borders and for colonizing in wild open places, and for use in rockwork. Two of the species come as far East as Nebraska and Iowa.
