--><p><i>Peraphyllum</i> shares with <i>Amelanchier</i> and <i>Malacomeles</i> the feature of false partitions within the carpels that partially divide the locules and make the fruit appear to have twice as many locules as the number of carpels (G. N. Jones 1945; K. R. Robertson et al. 1991; J. R. Rohrer et al. 1991). Sequences from multiple chloroplast and nuclear genes indicate that <i>Amelanchier</i> and <i>Peraphyllum</i> are sister taxa (C. S. Campbell et al. 2007).</p>
