A new species of the genus Chamaecrista (Leguminosae, Caesalpinioideae) from Chapada dos Veadeiros, Goiás, Brazil

Researchers have identified and described a new species of the genus Chamaecrista, named Chamaecrista frondosa, from the Chapada dos Veadeiros National Park in Brazil. This discovery contributes to the understanding of biodiversity within the Cerrado Protected Areas, specifically highlighting its restriction to Cerrado sensu stricto and rocky fields. The species is morphologically similar to C. psoraleopsis but distinct due to unique traits such as caespitose, subshrubby habit, glandular trichomes on young branches and inflorescence axis, resin-dotted leaflets, and flowers with 10 fertile stamens. A key to the species of Chamaecrista sect. Absus series Microphyllae in the region is also provided, aiding future taxonomic studies. The study underscores the notable endemism and ecological significance of this area within UNESCO World Heritage Sites.
