design: DNA was extracted from 10-30 mg silica dried leaf tissue or herbarium material using the E.N.Z.A SP Plant DNA Mini Kit (Omega Bio-Tek, Norcross, Georgia, U.S.A.). Libraries were pooled and enriched with the COS 1061 bait kit (Mandel et al. 2014) designed for the Asteraceae family. Unenriched libraries were mixed with target-enriched libraries in a ratio of 3:2.
