--><p><i>Ceratiola</i> was treated formerly within Empetraceae, along with <i>Corema</i> and <i>Empetrum</i>. Phylogenetic studies based on morphological and molecular data (A. A. Anderberg 1994c; K. A. Kron et al. 2002; Li J. H. et al. 2002) indicate that the <i>Empetrum</i> and <i>Ceratiola</i> + <i>Corema</i> lineages form a monophyletic group nested consistently within <i>Ericaceae</i>. The phylogenetic relationship between <i>Ceratiola</i> and the North American species of <i>Corema</i> is not resolved fully, and molecular data suggest possible ancestral hybridization events between <i>Ceratiola ericoides</i> and <i>Corema conradii</i> (Li et al.). <i>Ceratiola</i> differs from <i>Corema</i> by having two to three flowers in leaf axils, petals present, and two seeds per fruit. <i>Empetrum</i> is distinguished readily from <i>Ceratiola</i> by having solitary flowers in leaf axils and six to nine carpels and a corresponding number of seeds per fruit.</p><!--
