--><p><i>Bigelowia</i> is recognized by its leaves basally disposed or in basal rosettes, slender, subscapiform stems, and densely corymbiform arrays of small, cylindro-turbinate, discoid heads with phyllaries in vertical ranks and yellow corollas. Karyotypes of <i>Bigelowia</i> species, as well as various floral features, resemble those of <i>Euthamia</i> (L. C. Anderson 1970, 1972), and a hypothesis of relationship has been tentatively confirmed by molecular evidence (M. A. Lane et al. 1996). G. L. Nesom (1994) placed <i>Bigelowia</i> closest to <i>Chrysoma</i>, <i>Euthamia</i>, <i>Gundlachia</i>, and Xylothamia on the basis of morphologic evidence.</p>
