|discussion=<p>The earliest botanical name for the plants here called <i>Trixis inula</i> is <i>Inula</i> trixis Linnaeus, 1760. In 1763, Linnaeus changed the name from <i>Inula</i> trixis to Perdicium radiale, which was based on the same type and is illegitimate under today’s rules of botanical nomenclature because the epithet trixis should have been used in 1763. The name <i>Trixis</i> radialis (Linnaeus) Kuntze, 1891, was based on Perdicium radiale of Linnaeus and has been used by some botanists; it is superfluous and illegitimate under today’s rules.</p>
