Genetic relationships in the Galactia-Camptosema-Collaea complex (Leguminosae) inferred from AFLP markers

Some species belonging to the genera Galactia, Camptosema and Collaea from southern Brazil, Paraguay, Argentina, and Uruguay are grouped into a complex based on exomorphological affinities. The diagnostic morphological features sometimes overlap among species of different genera and dissimilar crite...
