Plants 60–80 cm. Stems glabrate, glandular. Leaves linear to narrowly oblanceolate (principal 1-nerved or 3-nerved), 8–35 × 1–2 (–3) mm, margins entire or sharply serrate.

Elevation: 0–100 m

Discussion

Of conservation concern.

Known only from coastal scrub in the Santa Lucia Range, northwestern San Luis Obispo County, subsp. glabrata is generally reduced in most characters than subsp. plummerae, with smaller heads and fewer florets (R. M. Beauchamp and J. Henrickson 1995).
