Abstract

We describe and illustrate two new species of Jatropha from Bahia State, Brazil: Jatropha longibracteata and Jatropha paganuccii. The two new species occur on limestone outcrops in seasonally dry tropical forests. We also provide a distribution map and IUCN conservation status, as well as morphological comparisons with the closely related species J. calcarea, J. martiusii, and J. palmatipartita.
