--><p><i>Geocaulon</i> is one of only two genera named by M. L. Fernald (the other being Alcoceria, Euphorbiaceae, now treated as a synonym of Dalembertia Baillon). Fernald stated that many features of <i>Geocaulon</i> are similar to <i>Nestronia</i> (Santalaceae); however, molecular data clearly indicate that <i>Geocaulon</i> is sister to <i>Comandra</i>.</p>
