Eriophyllum lanatum - Woolly eriophyllum

Family: Asteraceae (Aster family) [E-flora]

Description

  • General: "Perennial herb from a fibrous root; stems woolly, few- to much- branched from the base, 10-60 cm tall." [IFBC-E-flora]
  • Leaves: " Basal leaves few, soon deciduous; stem leaves alternate to opposite, entire to narrowly lobed, 1-8 cm long." [IFBC-E-flora]
  • Flowers: "Heads with ray and disk flowers, solitary on long stems; ray flowers 8-13, yellow, 1-2 cm long; involucres 9-12 mm tall; involucral bracts firm, erect, embracing the ray achenes." [IFBC-E-flora]
  • Fruits: "Achenes slender, 4-angled, glabrous to hairy; pappus of 6-12 translucent scales, or a toothed crown." [IFBC-E-flora]
  • Status: Native [E-flora]
  • Habitat / Range: "Dry meadows and rocky slopes from the lowland to the montane zones; common on Vancouver Island and the adjacent mainland, rare in SC and SE BC; S to MT, WY, UT and CA." [IFBC-E-flora]

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]

Eriophyllum Sp. - Woolly Sunflower

"Annual to shrub, ± woolly. Leaf: generally alternate, proximal sometimes opposite, entire to nearly compound. Inflorescence: heads 1–many, generally radiate; often in ± flat-topped clusters; involucre obconic to hemispheric; phyllaries 4–13(15) in 1 series, free or ± fused; receptacle flat to columnar, smooth or pitted (occasionally 1–6 palea-like scales at tip). 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. Fruit: 4(5)-angled or outer fruits flattened, inner fruits generally club-shaped; pappus of 0–15 ± jagged or fringed scales.

Local Species;

  • Eriophyllum lanatum var leucophyllum - Woolly eriophyllum [TSFTK][PCBC][E-flora]

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]
