|discussion=<p>Occurring along the coast and in interior valleys, <i>Baccharis douglasii</i> 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 <i>Baccharis</i> pingraea de Candolle, and that the two taxa may be conspecific.</p>
