--><p><i>Astraea</i> was treated as a section of <i>Croton</i> by G. L. Webster (1993). However, the molecular phylogeny of P. E. Berry et al. (2005) showed that it represents a lineage distinct from <i>Croton</i>. Morphological characters that support this separation include the markedly rectangular seeds, the often deeply lobed leaves, and the mixture of simple and stellate hairs. <i>Astraea</i> is most diverse in southeastern Brazil.</p>
