9e. Eriophyllum lanatum (Pursh) J. Forbes var. lanceolatum (Howell) Jepson, Man. Fl. Pl. Calif. 1118. 1925.

Eriophyllum lanceolatum Howell, Fl. N.W. Amer., 355. 1900

Perennials (± taprooted). Proximal leaves alternate; blades lanceolate to ovate, margins coarsely serrate or entire, plane, faces densely woolly. Heads usually borne singly, sometimes 2–3 per array. Peduncles mostly 3–10(–15) cm. Involucres 12–15 mm diam. Ray florets 10–15; laminae 7–10(–15) mm. Cypselae (1.9–)2.5–3.2 mm; pappi 0.5–1.4 mm. 2n = 16, 32.

Flowering May–Aug. Dry, rocky sites, oak/conifer forests; 200–2200 m; Calif., Oreg.

Although individuals of var. lanceolatum usually differ strikingly from most members of the other northern Californian varieties of the complex, sometimes they are similar. For example, L. Constance (1937) cited specimens of var. lanceolatum with features of varieties integrifolium or achillioides and we have found that most members of var. lanceolatum closely resemble plants of var. obovatum of southern California.
