Eriophyllum jepsonii Greene

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.

Eriophyllum jepsonii

provided by wikipedia EN

Eriophyllum jepsonii is a rare North American species of flowering plant in the family Asteraceae known by the common name Jepson's woolly sunflower. It is endemic to California, where it has been found in the Central Coast Ranges and adjacent hills from Contra Costa County to Ventura County.[1][2]

Eriophyllum jepsonii grows in dry habitat such as chaparral and oak woodland. This is a small shrub producing woolly, whitish stems 50 to 80 centimeters (20-32 inches) tall. It is lined with lobed oval leaves each a few centimeters long and coated in woolly fibers. The inflorescence produces one or more flower heads containing many glandular or bristly yellowish disc florets surrounded 6 to 8 yellow ray florets each up to a centimeter long. The fruit is an achene tipped with a pappus of approximately 8 scales.[3][4]
