Shrubs, 50–80 cm. Stems erect (densely white-woolly). Leaves (proximal alternate): blades ovate, 3–6 cm, 1-pinnatately lobed (lobes 5–7, linear), ultimate margins entire, revolute, abaxial faces woolly, adaxial glabrate (distal leaves gradually reduced in size and lobing). Heads 2–4 per array. Peduncles mostly 5–10(–14) cm. Involucres broadly campanulate, 5–7 mm diam. Phyllaries 6–8, distinct (ovate, carinate, apices acute). Ray florets 6–8; laminae yellow, 6–10 (× 4–5) mm. Disc florets 35–50; corollas 3–5 mm. Cypselae 2–3 mm; pappi of 8 lanceolate to lance-linear, erose scales 1–1.5 mm. 2n = 64.
Phenology: Flowering Mar–May.
Habitat: Dry sites, oak woodlands
Elevation: 200–500 m
Discussion
Of conservation concern.
Eriophyllum jepsonii occurs in Inner Coast Ranges and D. P. Tibor (2001) treated it as uncommon. It combines characteristics of E. lanatum and E. confertiflorum var. confertiflorum. Populations have been found as close as 10 m to either species. L. Constance (1937, p. 106) commented that it might be an “evolutionary link” between them.
