--><p>Chrysoma pauciflosculosa was originally described within Solidago; it is distinct in anatomy (F. E. Lloyd 1901; K. Phillips 1963; L. C. Anderson and J. B. Creech 1975) and other features. Chrysoma is recognized by its shrubby habit, areolate-resinous leaves, corymbiform arrays of glomerate, cylindric, few-flowered heads, long disc corolla lobes, and papillate style-branch appendages.</p>
