Resumen:
Phylogenetic analyses of 131 terminals of Paspalum
and related genera, based on both plastid and nuclear markers, were performed
under maximum parsimony and Bayesian methods. The total evidence analyses
generated a hypothesis showing that Paspalum would be monophyletic if Spheneria,
Thrasyopsis and Reimarochloa are included within the genus. Paspalum
inaequivalve and P. microstachyum, two species of the Inaequivalvia
group were related to genus Anthaenantiopsis, excluded from Paspalum,
or nested within it by plastid and nuclear markers, respectively. Subgenera Anachyris
and Harpostachys were partially recovered as monophyletic
assemblages, while subg. Ceresia and Paspalum resolved as polyphyletic.
Within subgenus Paspalum, some informal groups were recovered as
monophyletic, while others were resolved as paraphyletic or polyphyletic.
Phylogenetic relationships among species of Paspalum were partially
recovered possibly due to reticulation events among species,
autopolyploidization and apomixis; being all these processes common in Paspalum,
hence obscuring the infrageneric classification.
