• Astronium urundeuva

In 1968, F.A. Barkley describes the genus Astronium as composed of 13 species.

• Subgenus Euastronium

1. Astronium ulei
2. Astronium lecointei
3. Astronium glaziovii
4. Astronium obliquum

11. Astronium urundeuva
12. Astronium balansae
    • Subgenus Myracrodruon, Section Macrocalyx
13. Astronium concinnum

More recently, Santin and Leitão-Filho (1991) elevated the status of Myracrodruon from subgenus to genus. Apparently, Santin also placed Astronium concinnum into a new genus; Hermogenodendron. Further, Santin (1991) added a new species to the genus Astronium; Astronium nelson-rosae. Pell et al. (2011) lists the genus as having seven or more species.
