Jacobina is located at the northern end of Chapada Diamantina and is composed by two main mountains: Serra do Tombador in the western portion, and Serra de Jacobina in the eastern portion. The study aims to survey the flora of Asteraceae of the municipality of Jacobina, discuss occurrence and distribution, and provide a key for species. Samples were collected during five field trips (2011‑2012) to different vegetation types and analysis of seven Brazilian herbaria collections. The family is represented by 15 tribes, 61 genera, 80 species, and one hybrid.

Among the studied taxa, ten have Jacobina as type locality. Lepidaploa muricata is a new record for the Bahia State.
