Discussion
Genus 1, species 29 (1 in the flora).
Iteaceae, which has been included in Grossulariaceae (A. Cronquist 1981) or Escalloniaceae (R. F. Thorne 1992b), has a disjunct distribution, with Itea virginica in southeastern North America and other species in southeastern Africa and southeastern Asia. Molecular data place it sister to the Mexican genus Pterostemon S. Schauer within the core Saxifragales (M. Fishbein et al. 2001).
