Lomatium is a genus of about 75 species of perennial herbs native to western North America. In the Apiaceae family and related to many edible species such as carrots and celery, it is also edible. The common names for it are biscuitroot, Indian parsley, and desert parsley, and was extensively used by Indians in the inland northwest as a staple food.

Lomatium Cous Biscuitroot Cousroot Desert Parsley Lomatium cous Synonyms

Roots range from woody taproots to more fleshy underground tuberous-thickened roots. Most lomatiums are desert species or grow on bluffs where water is limited for most of the year. They are green and grow the most during the spring when water is available, then set seed and dry out completely above ground before the hottest part of the year, while storing the energy they gained from photosynthesizing while water was available to them in their deep roots. For most of the year, the plant is not visible; the brown tops often are blown off or easily crushed, but it lies dormant underground for the next spring.

The flowers are arranged in compound umbels, without involucral bracts (or with inconspicuous bracts). The flowers are white or yellow, more rarely a purple or maroon color. As with most Apiaceae, the fruit sets the genus apart from other yellow- or white-flowered look-alikes such as Cymopterus and Oreogenia. Uniquely, they are dorsally flattened and winged, which can be papery or corky, but help the seed to disperse further on the wind. The dorsal ribs may or may not be on the fruit, but are narrowly winged if at all. Leaves are mainly basal and dissected (ternately, pinnately, or ternate-pinnately dissected or compound), many look like ferns or can be mistaken them.

Ecology

Lomatium Lomatium

It grows in a variety of habitats throughout western North America, from coastal bluffs to piles of basalt rock.

Conservation concerns

Many species' habitats are under threat by grazing, development, and wildfires. Also, some concern exists about particular species such as L. dissectum, which is mainly harvested from the wild for herbal uses.

Because the genus is so difficult to identify, but has great genetic diversity, new species are still being found today such as L. tarantuloides, many species often have a very limited range, they exist nowhere else, and are few to begin with.

Cultivation and uses

Several species, including L. cous, L. geyeri, and L. macrocarpum, are sometimes known as biscuit roots for their starchy edible roots. These are or have been traditional Native American foods, eaten cooked or dried and ground into flour. Some Native Americans ground Lomatium into mush and shaped it into cakes and stored them for later use. Their flavor has been compared to celery, parsnip, or stale biscuits.

L. dissectum has been used as herbal medicines for cough and upper respiratory infections, including tuberculosis.
