Phylogenomics recovers monophyly and early Tertiary diversification of Dipteronia (Sapindaceae).

Dipteronia (Sapindaceae) is an ancient relict woody genus, and contains just two extant species endemic to Southwestern and Central China. As sharing numerous morphological characters, Dipteronia and Acer have long been considered as sister groups forming the traditional family Aceraceae. However, molecular phylogenetics has generally not resolved the phylogenetic placement of Dipteronia, especially not in its expected position as sister to Acer.
