SUMMARY
This work is a taxonomic revision of the species in the genus Vataireopsis Ducke (Leg. Fab.). This genus is found only in the neotropical region and is limited to Perenial Broadleaf Evergreen Hylean Forest. The taxonomic treatment includes descriptions, illustrations, discussions about the degree of affinity, the geographic distribution and fenological data.
The most significant characters in delimitation of species are the morphology of calyx, androecium, bracteas, bracteolas and fruits. A dichotomic key for identification of species has also been presented. A new species has been included and another excluded.
Also included is a table showing differential characteristic among the genus Vatairea, Vataireopsis (Dalbergieae) and Luetzelburgia (Sophoreae).
