Description

Ecological Indicator Information: "A very shade-intolerant, submontane to montane, Western North American forb distributed equally in the Pacific and Cordilleran regions. Occurs in cool temperate and cool mesothermal climates on excessively dry to very dry, nitrogen-medium soils. Its occurrence increases with increasing precipitation and elevation. Grows in non-forested, grassy communities very shallow, on water-shedding sites; often inhabits disturbed sites. Characteristic of moisture-deficient sites." [E-flora]

"Another possibility is for small-scale production of the major acetylenes produced by the roots; root cultures of Eriophyllum lanatum have been used in this way." [Bajaj MAPS 3]

Ray flower: 0 or generally ± 1 per phyllary; ray entire to lobed, generally yellow (white). Disk flower: (3)10–300; corolla yellow; anther tip ovate, deltate or awl-shaped; style tips ± ovate, papillate.

Local Species;

Food Use

"Eriophyllum seeds were parched and ground into a flour by Cahuilla and Luiseno Indians in California. The seeds were also incorporated into pinole." [Vizgirdas WPSN]

Phytochemicals

"Seven species have been studied for flavonoids by Rarborne and Smith (1978): E. ambiguum, E. confertiflorum, E. lanatum var. obovatum, E. multicaule, E. pringlei, E. staechadifolium, and E. wallacei. Quercetin 5-0-glucoside, quercetagetin 7-0-glucoside, and patuletin 7-0-glucoside were identified, although not all taxa exhibited all three compounds." [Bohm FSF]
