Classification of the Relhania generic group (Asteraceae, Gnaphalieae) revisited using molecular phylogenetic analysis

Phylogenetic relationships within the Relhania generic group, a southern African lineage of 45 yellow-flowered daisy species, are examined using parsimony and Bayesian analysis of plastid DNA, nuclear DNA, and morphological characters. The resulting phylogenetic hypothesis indicates that the species fall into two clades, one comprising the genera containing short-lived (annual / biennial) species, and the other exclusively perennial. Within the...
