Baccharis glutinosa
Baccharis brachyphylla
Occurring along the coast and in interior valleys, Baccharis glutinosa is recognized by the erect, simple stems growing in patches from rhizomes, large lanceolate leaves with three veins and blackish glandular dots, heads in dense, compact, terminal, corymbiform arrays and more or less uniform inner phyllaries. G. L. Nesom (1990h) noted that it is similar to forms of the South American species Baccharis pingraea de Candolle, and that the two taxa may be conspecific.

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.
