Combined morphological and molecular data support a clade of Halesia, Melliodendron, Parastyrax, Pterostyrax, and Rehderodendron (P. W. Fritsch et al. 2001). All of these genera share the same type of ovary architecture, with two apotropous distal ovules and two epitropous proximal ovules per carpel, as well as similarities in fruit and seed morphology. The genus is unusual for an eastern Asian-eastern North American disjunct in that more species occur in North America than in Asia. A morphological phylogenetic estimate of Halesia places the two North American taxa as the sister group of the Asian species H. macgregorii Chun. In contrast, DNA sequence data place H. macgregorii as sister to Rehderodendron and the two United States species as unresolved as to their closest relative (Fritsch et al.).
