--><p><i>Dionaea</i> has been placed in its own family, Dionaeaceae Rafinesque. This is not without merit, as virtually all of its diagnostic features are different from those of <i>Drosera</i>. Molecular analysis places it in the Droseraceae in the narrow sense (K. M. Cameron et al. 2002; S. E. Williams et al. 1994; F. Rivadavia et al. 2003).</p>
