Resumen:
Abstract 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 criteria have been adopted to
delimit them, thus generating great taxonomic uncertainty.
The aim of this work was to clarify the genetic relationships
of the species within the complex as well as to analyze the
infraspecific variability by means of analysing the AFLP
band patterns. We examined 378 AFLP markers generated
after amplification using six primer combinations. The
monophyly of Collaea was supported, corroborating the
present morphological classification. On the other hand, the
results are not congruent with the current circumscription
of Galactia and Camptosema, in agreement with previous
phylogenetic hypotheses based on morphological
characters and karyological studies, as both genera are
polyphyletic.
