Baccharis malibuensis
Baccharis brachyphylla
Of conservation concern.
Baccharis malibuensis is known only from the Malibu Creek drainage area in the Santa Monica Mountains (Los Angeles County). It is distinguished by its narrow, often conduplicate and glabrate leaves, cylindric arrays, and summer flowering. According to Beauchamp and Henrickson, it appears to be closely related to and possibly derived from B. plummerae, from which it differs primarily in leaf size, teeth, and indument.

Baccharis brachyphylla is characterized by the densely branching habit, narrow stems, and small, linear-lanceolate leaves, and hispidulous hairs on stems, leaves, phyllaries, and cypselae.
