Tricky Morphology: A New Species of Chamaecrista (Leguminosae) Shows Strong Morphological Convergence Among Not Closely Related Species Found in Similar Habitat
Abstract:Abstract— Plants from Brazilian campos rupestres usually present morphological strategies that allow them to survive in extreme environments. However, in Chamaecrista (Leguminosae, Caesalpinioideae), one of the most diverse genera in the campos rupestres, needle-like
leaflets are rare. Reviewing the species that present such leaf morphology, we describe Chamaecrista acicularis, a new species from the Canastra Range, in the southwestern region of the state of Minas Gerais, Brazil. Phylogenetic analyses reveale… Show more
