Baccharis plummerae subsp. glabrata
Baccharis plummerae
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).

Subspecies 2 (2 in the flora).
Baccharis plummerae is recognized by the bushy habit, wandlike, densely villous or glabrate stems, narrowly oblong leaves with sharply serrate margins, and densely villous or glabrate leaves, phyllaries, and cypselae. It is morphologically similar to B. malibuensis.
