Genomic DNA was extracted from leaf material stored in silica gel using a DNA extraction kit  (Qiagen DNeasy Plant Mini Kit) following the manufacturer's instructions. The RAD library was prepared as in Balao et al. (2020. Annals of Botany 125:495-507). Genomic DNA was digested by using high-fidelity sbfI (New England Biolabs) and the resulting fragments were double barcoded.
