The genus is represented in Brazil by 256 species, of which 97 are cited for the northeast Region. The Ecological Station Raso da Catarina (ESRC) is one of the largest areas of protected Caatinga and occupies about 105,282.00 ha., delimited by the coordinates 09°39'0.30" to 09°50'98.2" S and 38°26'57.5" to 38°29'32.6" W. The floristic survey of Chamaecrista in the ESRC included analysis of specimens collected from March 2010 and October 2011. The analyses were supplemented with dried collections from the following herbaria: ALCB, EAC, HRB, HUEFS and MBM. The genus is represented in the study area by ten taxa. The most representative taxa in the area were Chamaecrista repens (Vogel) H
