ABSTRACT Aim The outstanding Andean biodiversity has been linked to the occurrence of evolutionary radiations that are common among high‐elevation plant lineages. One most iconic examples is found in species‐rich genus Senecio , with an impressive variation growth forms and habitat preference. Here, we use Hyb‐Seq overcome lack phylogenetic resolution previous studies aim disentangling processes shaping Senecio's hyper‐diversity Andes, including evolution woodiness, form Location Central Northern Andes. Taxon ser. Culcitium. Methods data for 104 accessions were newly generated analysed using a analysis workflow utilises paralogs reconstruction. robustness species tree under different missing treatments was investigated, phylogeny dated. role hybridisation diversification this lineage addressed. morphological key features changes preferences evaluated. In addition, association these rate heterogeneity tested. Results Culcitium monophyletic lineage, likely Pleistocene origin. Hybridisation, possibly promoted by altitudinal range shifts during climatic oscillations, played important its evolution. We evidence several events south‐to‐north migration from puna on Andes páramo migrations resulted dramatic diversification. Habitat montane forest occurred multiple times associated shifts. Main Conclusions With net 2 per million years, fastest diversifying lineages documented so far region. Frequent form, crucial lineage.
