Revised taxonomy of the Arctotis Annual Clade (Arctotideae, Asteraceae) from Southern Africa: integration of molecular phylogenetic and morphological evidence
<p>Previous phylogenetic analysis of ITS nrDNA sequence data for Arctotidinae species resolved a highly supported clade containing all but one of the showy annual <i>Arctotis </i>species (informally designated the '<i>Arctotis</i> Annual Clade')<i>.</i> In the present study, phylogenetic relationships in the <i>Arctotis </i>Annual<i> </i>Clade were investigated by Bayesian inference and maximum parsimony analyses of cpDNA (<i>trnT-trnL-trnF</i> and <i>trnH-psbA</i>) and nrDNA (ITS) sequence data. The cpDNA and nrDNA phylogenies were notably incongruent. <i>Arctotis venusta </i>and a putative unnamed species<i> </i>('sp. B') were highly supported as monophyletic by both datasets. The monophyly of <i>A. leiocarpa </i>was strongly supported by the ITS dataset, whereas the remaining accessions formed a poorly resolved complex (the '<i>A. fastuosa </i>complex'). Within the <i>A. fastuosa </i>complex, <i>A. hirsuta </i>was monophyletic with high support in the ITS phylogeny. A statistical parsimony-derived cpDNA haplotype network resolved five broad groups of haplotypes and showed no consistent geographical structure, but species-specific haplotype lineages<i> </i>for<i> A. venusta </i>and sp. B were resolved. <i>Arctotis fastuosa </i>accessions were distributed among four haplotype groups. Incongruence between the datasets and poor resolution within the <i>A. fastuosa </i>complex may reflect reticulate evolution, ancestral polymorphism, and incomplete lineage sorting, in tandem with the low information content of the datasets. The greatest phenotypic diversification in the clade is in cypsela morphology. Comparison of cypsela morphology with the phylogenies suggests a general trend for reduction in the sizes of the cypsela, abaxial wings, and pappus scales, and loss of pubescence during diversification. A revised taxonomy, integrating currently available evidence, accompanied by full descriptive accounts and a key to the taxa are presented. Eight species are recognized, including the nomenclatural novelties <span><b><i><span>Arctotis chrysantha</span></i></b></span> (sp. nov.) and <span><b><i><span>Arctotis namibiensis</span></i></b></span><i> </i>(sp. nov.). The names <i>Arctotis karasmontana</i>, <i>Venidium fugax</i>, and <i>Venidium macrocephalum</i> are lectotypified.</p>
