|discussion=<p><i>Pyrrocoma linearis</i> is easily distinguished by its linear, entire, grasslike leaves, and terminal, single heads. This species is similar to <i>P. uniflora</i> and was formerly included there as a subspecies. <i>Pyrrocoma uniflora</i> differs in having lanceolate or oblanceolate leaves with dentate margins.</p>
